3.2.3. Device Charging
A single external power supply with a 3.5mm DC connector or SAE connector is necessary to operate the TRIUMPH-3NR. If external power supply has only an SAE connector, the Receiverto-SAE power cable is be used. The external power supply needs to be approved for the US and EU, and have an output rated for 10 – 30 V DC, 3A. This may not be the same range as other JAVAD GNSS products. To avoid the introduction of hazards when operating and installing, before connecting the TRIUMPH-3NR to the supply, make sure that the supply meets local and national safety ordinances and matches the equipment’s voltage and current requirements.
Warning: Never attempt any maintenance or cleaning of the supply while plugged in. Always remove supply from AC power before attempting service or cleaning.
If the voltage supplied is below the minimum specification, the receiver will suspend operation. If the voltage supplied is above the maximum specification, the receiver may be permanently damaged, voiding your warranty.
Make sure cords are located so that they will not be stepped on, tripped over, or otherwise subjected to damage or stress. Do not operate the TRIUMPH-3NR with a damaged cord or plug – replace immediately. To reduce the risk of damage to the TRIUMPH-3NR, pull by the plug body rather than the output cord when disconnecting the equipment.
Warning: Do not operate the power supply if it has received a sharp blow, been dropped, or otherwise damaged. Do not disassemble the power supply.
The TRIUMPH-3NR comes from the factory with the batteries charged and ready to use so you can begin exploring its interface and familiarizing yourself right away while reading this manual.

RTK / Post-Processing Configuration

When configuring receivers for RTK surveying, use the following list to ensure the receivers are properly set up:

• Configure one receiver as an RTK Base station and the other receiver as an RTK Rover.
• Configure the communication data link for transmitting and receiving corrections.
• Set up the Base receiver over a known point to begin collecting static observation data and transmitting corrections. Set up the Rover receiver to begin collecting RTK data.

When configuring receivers for post-processing surveying, use the following list to ensure the receivers are properly set up:

• Configure one receiver as a Rover.
• Set up the Rover receiver to begin collecting measurements data.
• Configure RTPK parameters and source for post-process surveying.
• Apply RTPK calculations for the measurements made with the Rover.

5.1. RTK Setup for Base and Rover
The following Base and Rover configurations are recommended for the most common applications. However, you can select configuration parameters as needed for your particular jobsite.
Note: Do not make other changes without consulting the NetView&Modem Software Manual.

serial number. By default, the prefix is log
REC (FN) key mode| (starts/stops the data recording when FN button is used)
Select LED blink mode switch for Static data| Select Occupation mode switch (for RTK)
Initial dynamic mode| –| Select Dynamic (for trajectory survey)

1. Connect the receiver and computer, start NetView&Modem and establish the connection as described above.

2. Click Receiver>Parameters on the left panel.

3. In the General tab check antenna status of the parameter Antenna Input to be Internal (External antenna input is not available for TRIUMPH-3NR).

4. Open the Log files tab and then TriPad tab and set the following parameters, click Apply.

5. Open the Positioning tab and set the Elevation mask (15° is recommended).

6. To set up the base station, open the Base tab and set the following parameters:
   Antenna Phase Center Position (APC) – enter latitude, longitude, and altitude (ellipsoidal height) values of the antenna position. Do one of the following:
   • If known, type in the values.
   • Click Get from receiver to use the current antenna position.

7. Restart your receiver. Open the Base tab and check coordinates. Click Refresh, to refresh the parameters.

8. To set up the rover, open the Positioning tab and set the Position Computation Mode
   – this drop-down list box allows selecting the mode of position computation:
   • pd -carrier phase differential (RTK) with fixed ambiguities
   • pf – carrier phase differential (RTK) with float ambiguities
   • cd- code differential (DGPS) mode
   • wd – wide area code differential mode (WDGPS)
   • sp – single point positioning mode1

9. Open the Rover tab and set up the following parameters:
   • RTK Position Computation Mode – select Extrapolation for RTK float (kinematic), or Delay for RTK fixed (static). If Extrapolation is selected, the rover will extrapolate the base station’s carrier phase measurements when computing the rover’s current RTK position. If Delay is selected, the rover will not extrapolate the base station’s carrier phase measurements to compute the current rover position.
   Instead, the RTK engine will compute either a delayed RTK position (for the epoch to which the newly received RTCM/CMR message corresponds) or the current stand-alone position (while waiting for new RTCM/CMR messages coming from the base).
   • Confidence Level for Ambiguity – list box governs the process of the RTK engine fixing integer ambiguities. Low, Medium and High correspond to the indicator’s 95%, 99.5% and 99.9% states, respectively. The higher the specified confidence level, the longer the integer ambiguity search time. This is the price one pays for the higher reliability of the ambiguity fixed solution.

10. For RTK survey, open the Ports tab and set up the parameters according to the table below, then click Apply.
    Note: For the survey with the post-processing keep default parameters. Parameter| Base| Rover
    ---|---|---
    Input| –| The same correction type as Base
    Output| Select the correction type| –
    Period (sec)| Set the period of correction output| –
    Baud rate| Baud rate for the corresponding receiver port
    RTS/CTS| Enable| Enable

11. Open Advanced tab, and then Multipath Reduction subtab. Activate Code multipath reduction on base and rover for DGPS mode. For RTK mode activate Carrier multipath reduction as well.

12. Click Apply, to save the made changes and settings into receiver’s memory and close the dialog window. The receiver configuration will be kept in the receiver until changed or the NVRAM is cleared.
    Note: For detailed description of settings and parameters, please see the NetView&Modem Software Manual.

Setup and Survey

After configuring the receivers for surveying, each receiver needs to be setup up and the receiver’s height measured before the survey can begin. The MinPad provides quick access for logging data, changing receiver modes, and viewing general data logging and satellite information during a survey.
A typical GPS survey system consists of a Base station set up over a known point and a Rover receiver set up to be a mobile data collector. After setting up the Base and Rover receivers, the antenna height must be measured.
Before collecting data, make sure the Base and Rover receivers contain a current almanac and current ephemeris data.
The Base station must be set up, logging data, and transmitting data before setting up the Rover receiver. Receiver setup for either post-process or RTK surveys is the same.

6.1. Antenna Height
The location of the antenna relative to the point being measured is very important for both surveys in which the elevation of the points is important and in surveys for horizontal location only. Horizontal surveys are often larger in area than can reliably fit on a flat plane, therefore the antenna adjustment must be done in three dimensions and then projected onto a twodimensional plane.
The receiver calculates the coordinates of the antenna’s phase center. To determine the coordinates of the station marker, the user must specify the following:

• Measured height of the antenna above the station marker
• Method of measuring the antenna height
• Model of the antenna used.

Antennas have two types of measurements:

• Vertical – measured from the marker to the antenna reference point (ARP) located on the bottom of the receiver at the base of the mounting 1/4 thread.
• Slant – measured from the marker to the lower edge of the antenna slant height measure mark (SHMM) located on the side panel of the receiver (green triangle).

The point to which surveying with GNSS measures is called the Antenna Phase Center (APC).
This is analogous to the point at which a distance meter measures in a prism. A user must enter the prism offset to compensate for the difference in distance from the surface of the prism to the center of the object measured. For a GNSS antenna, the offset is entered depending on the type of measurement taken.
To prevent tilting of the receiver, you can use embedded IMU module, which determines deviations from the vertical (relative Earth surface) in real time.
For vertical, the offset is simply added to the measured vertical height to produce a “true” vertical height. For example, surveying poles can be set on specific height. In this case the “true” height will be summary of pole length set and adapter height (if you use one).
For slant height, the vertical height must first be calculated using the radius of the antenna, then the offset can be added.
The offsets are different because of the difference in location between the slant measuring point and the vertical measuring point.
Measure the antenna height to the control point or marker edge, either the slant height or the vertical height.

6.2. Data Logging
See the remaining sections in this chapter for more information on data logging.

• Turn on the receiver.
• Once the receiver has locked onto eight or more satellites the SAT light will green.
• The red color of POS LED indicates that the receiver has not solved a position. Four or more satellites provide optimal positioning.
• Once the red POS LED is green, the receiver has a position and surveying can begin; wait for green light before beginning data collection. This ensures that the receiver has the correct date and time and is locked on to enough satellites to ensure good quality data.
• The process of locking onto satellites normally takes less than one minute. In a new area, under heavy tree canopy, or after resetting the receiver, it may take several minutes.
• To begin collecting data, press and hold the Record (FN) button (for more than one second and less than five seconds).
• Release the Record button when the REC (recording) LED turns green. This indicates that a file has opened, and data collection has started. The REC LED blinks each time data is saved to the internal memory.

When finished, press and hold the Record button until the REC LED light goes out.
To turn off the receiver, press and hold the power button until all lights go out, then release.

6.3. Static Survey
Static surveying is a classic survey method, well suited for all kinds of baselines (short, medium, long). At least two receiver antennas, plumbed over survey marks, simultaneously collect raw data at each end of a baseline. These two receivers track four or more common satellites, have a common data logging rate (5–30 seconds), and the same elevation mask angles. The length of the observation sessions can vary from a few minutes to several hours. The optimal observation session length depends on the following factors:

• The length of the baseline measured.
• The number of satellites in view.
• Satellite geometry (DOP).
• The antenna’s location.
• The ionospheric activity levels.
• The types of receivers used.
• The accuracy requirements.
• The necessity of resolving carrier phase ambiguities.

Generally, single-frequency receivers are used for baselines whose lengths do not exceed 15 kilometers (9.32 miles). For baselines of 15 kilometers or greater, use dual-frequency receivers.
Dual-frequency receivers have two major benefits. First, dual frequency receivers can estimate and remove almost all ionospheric effect from the code and carrier phase measurements, providing much greater accuracy than single- frequency receivers over long baselines or during ionospheric storms. Secondly, dual-frequency receivers need far less observation time to reach the desired accuracy requirement.
After the survey is complete, data the receivers collect can be downloaded onto a computer and processed using post-processing software (for example, JAVAD GNSS Justin3).

6.4. Kinematic Survey
In a kinematic or a stop and go survey, the stationary receiver (Base station) is set up at a known point such as a survey monument, or an unknown point. The receiver continually tracks satellites and logs raw data into its memory. The Rover receiver is set up at an unknown point and collects data in static mode for 2 to 10 minutes. When finished, assign the Rover to kinematic status, and move to the next survey point. At this point, and each subsequent point, the receiver is changed to static mode to collect data. So, while moving, the Rover is in kinematic mode, and while collecting data, the Rover is in static mode.

• Set up the Rover at an unknown point and press the Power button.
• Allow the Rover to collect static data for two to ten minutes. The REC LED will be yellow.
• Check the SAT light for satellites tracked.
• When finished, press the Record (FN) button for less than 1 second to assign the Rover to kinematic.
• Move the Rover to the next location (survey point) and press the Record (FN) button for less than a second to collect the data in static mode for two to ten minutes.
• Repeat the two previous steps until all points have been surveyed. The occupation time for the points depends on the same factors as for the static survey method.

When finished, press the Record (FN) button for one to five seconds to stop logging data. Turn off the Rover if needed. This method of GNSS survey allows the operator to reduce the point occupation time, thus permitting field crews to survey many more points compared to the other methods available.

6.5. RTK
With RTK surveying, as with kinematic surveying described above, one receiver serves as the reference station and conducts observations with its antenna affixed to a stationary tripod or some other device. The other receiver functions as a rover and conducts observations (using an antenna) affixed to a mobile pole and moved to observation points.
Unlike post-processed kinematic surveys, RTK surveys utilize a communications link between the Base and Rover. Using a radio modem link, the Base receiver transmits its measurement and location data to the Rover receiver. The Rover, based on the transmitted data and its own observation data, immediately conducts a baseline analysis and outputs the results.
Usually, the receiver will start to output the coordinates of the antenna’s phase center along with the solution type within 10–30 seconds. However, UHF radios and GSM phones may take as long as 60 seconds to synchronize. The geodetic coordinates displayed on the Location tab are always computed in WGS84 and have four solution types.

1. Standalone – where the receiver computes 3D coordinates in autonomous mode without using differential corrections.
2. Differential (DGPS) – where the Rover receiver computes the current relative coordinate in differential mode using only pseudo ranges.
3. Float RTK – where the Rover receiver computes the current relative coordinates in differential mode using both pseudo ranges and phases; however, with a float solution, the phase ambiguity is not a fixed integer number, and the “float” estimate is used instead.
4. Fixed RTK – where the Rover receiver computes current relative coordinates, with ambiguity fixing, in differential mode. The LQ field reflects the status of the received differential messages and contains the following information:
   • Data link quality in percentage.
   • Time (in seconds) elapsed since the last received message.
   • Total number of received correct messages (dependent on the message type received).
   • Total number of received corrupt messages (dependent on the message type received).
   • If the receiver is not (for some reason) receiving differential corrections, or if none of the ports has been configured to receive differential corrections, the LQ field will either be empty or it will look like this: 100% (999,0000,0000).

6.6. File Maintenance
If post-processing the data after completing a task, the data in the receiver’s memory will need to be downloaded to a PC. Downloading and deleting files will also prepare the receiver’s memory for the next task. Occasionally, the receiver’s NVRAM may need to be cleared to eliminate communication or tracking problems. As project expectations expand, the receiver’s OAF may need to be updated to provide expanded operation and functionality. The receiver requires firmware to properly operate and provide  appropriate functionality. As JAVAD GNSS releases firmware updates, loading these updates into the receiver will ensure that the receiver operates at its full potential.
When measuring is complete, download the files to a PC for storage, post- processing, or backup. Also, the memory holds a finite amount of data, so downloading the files to a computer ensures that no data is lost or overwritten. Download files as soon as possible after collecting data at the jobsite.

• Connect your receiver and computer. Start NetView&Modem. Establish a connection between NetView&Modem and receiver.
• Click Files on the left panel. On the right panel appears the list of files, saved in receiver’s memory. Select the file(s) to download:

Click the Download button. During the download, status indicators display each file.
To delete files from your receiver click Delete. Click Yes at the delete files confirmation dialog box. NetView&Modem will delete the selected files.

Troubleshooting

Warning: Do not attempt to repair equipment yourself. Doing so will void your warranty and may damage the hardware.

8.1. Prior to Contacting Support
Before contacting JAVAD GNSS support, check the following:

• Check all external receiver connections carefully to ensure correct and secure connections. Double check for worn or defective cables.
• Check all power sources.
• Check that the most current software is downloaded onto the computer and that the most current firmware is loaded into the receiver. Check the JAVAD GNSS website for the latest updates.

Then, try the following:

• Reset the receiver using NetView&Modem: Receiver name (on the left panel) 4Actions 4Reset.
• Restore default settings using NetView&Modem Receiver name (on the left panel).
• Clear the NVRAM.

If the problem persists, see the following sections for other solutions.
For NVRAM cleaning do the following:

• Turn the device off.
• Press and hold Record (FN) button.
• While Record (FN) button is held, press Power button for 1-2 seconds to turn the receiver on.
• Wait until both first and last LEDs turn green.
• In five seconds, both LEDs will blink orange.
• Release Record (FN) button while LEDs are blinking. Note that you have only five seconds while orange-blinking state is on to clean NVRAM.

FAQ

The following are some of the most common receiver problems.

The receiver port used for connection is not in Command mode.

• Connect your receiver and PC using a free port and start NetView&Modem. • Change the Input for the port used for connection to “Command”.

The receiver does not lock on to satellites for a long period of time.

• Check current OAF options. • Order a new OAF with the desired options activated to enable or extend validity of the corresponding receiver options. Contact your dealer or visit the JAVAD GNSS website for details. • Refer to the NetView&Modem Software Manual for a detailed description of options.

The receiver tracks too few satellites

• The elevation mask value is too high. • Lower the elevation mask.

The measuring is conducted near obstructions (tree canopy, tall buildings, etc.).

• Check that the Multipath Reduction boxes have been enabled. • Connect your receiver and PC using a free port and start NetView&Modem. • Click enable Multipath reduction and click Apply. • Move to an area free of obstructions, if applicable.

The receiver cannot obtain Code Differential and/or RTK solutions.

• Incorrect Base coordinates entered. • Specify the correct coordinates for the Base station using NetView&Modem or another suitable field data collection software.

The receiver is not configured as a Base or Rover.

• If the receiver should function as a Base, ensure it has the proper configuration. • If the receiver should function as a Rover, ensure it has the proper configuration. • The corresponding receiver options may be disabled or expired. • Order a new OAF with the desired options activated to enable or extend validity of the corresponding receiver options. Contact your dealer or visit the JAVAD GNSS website for details. • Refer to the NetView&Modem Software Manual for a detailed description of options.

There are not enough common satellites.

• In order to obtain a fixed solution, the Base and Rover should track at least five common satellites. • Ensure that both the Rover and Base receivers use the same, and updated, almanac. • Check the elevation masks of the Rover and Base receivers; they should be the same.

A discrepancy exists between the differential standards used at the Base and Rover receivers.

• Ensure the Base and Rover receivers use the same corrections input/output format: • Connect your receiver and a computer and start NetView&Modem. • Click the Ports tab. Use the same input/output format for both receivers.

Poor satellite geometry (PDOP/GDOP values are too high).

• Conduct your measuring when PDOP values are low.

The transmitting and/or receiving antenna may be improperly connected.

• Check that the radio modem’s antenna is securely and properly connected to the antenna connector. • Check that the radio modem’s antenna is undamaged. If damaged, contact your JAVAD GNSS dealer to replace the antenna.

The specified baud rate is incompatible with the baud rates the receiver supports.

• The baud rate is the rate at which the receiver transmits differential messages to the receiver and vice versa. Change the baud rate to that which your receiver supports.

The Base and Rover receivers use different radio link parameters.

• Configure the Base and Rover radio receivers according to the procedures listed in the applicable section.

The distance between the Base and Rover is too far.

• Close the distance between the Base and Rover. • Use repeaters to increase radio coverage. • There may be a source of radio interference that disrupts radio communications. • Change the RF channel (if possible). • Use a spectrum analyzer to detect the radio characteristics of the interfering signal and change your system’s configuration accordingly. • Remove the source of jamming signal or relocate your radio antennas (if possible).
