 Introduction

RTK15D series products are compact portable devices that can quickly equip smartphones with centimeter-accurate RTK. They are easy to use and do not require any complicated wireless or Bluetooth paring and connection operations. For the first-time use, just install the mobile APP on your smartphone, enter NTRIP settings, and you are ready to use. After that, as long as the device is plugged into the smartphone, the APP will automatically pop up and start high-precision RTK positioning.
RTK-15D which supports GNSS frequency L1+L5.
Getting started

1. Download the mobile APP named RTKFox-15D from Play Store and install it.

2. Open the RTKFox-15D APP, touch the “Configuration” button, and allow it to access data as below pictures.
   

3. Touch the button in the upper right corner. Then select “Configuration”.

4. Select Role as Rover. Enter NTRIP settings including IP, Port, User, and Password. Then touch the “Get List” button and select “Mount Point”. You can touch “Key in” button to enter Mount Point, too. If you want to log data of RTK position and GNSS raw data, turn on the switch of “Enable Log”. The data will be saved to the smartphone in the directory “Local storage>Device Storage>RTKFox-15D”. After finishing the settings, touch the button “Back”. All settings on this page will be saved.

5. Connect the USB cable to both the device (RTK15D series product) and your smartphone. Check the items and press OK as below pictures. These operations allow the APP to automatically pop up and start RTK positioning when the device (RTK15D series product) is plugged into your smartphone.

6. Now you can go outdoors to get a centimeter-accurate RTK position.

How to configure the device to be a base station?

In addition, to be a rover that provides RTK positioning, RTK15D series products can also be configured to be a base station. The steps are as follows.

1. Touch the button in the upper right corner. Then select “Configuration”.

2. Select Role as Base. Enter NTRIP settings including IP, Port, User, Password, and Mount Point. Scroll down and enter the Latitude, Longitude and Height of the device’s (RTK15D series product) antenna location. Note that it must be the actual correct location of the device’s antenna. If you want to log GNSS raw data, turn on the switch of “Enable Log”. The data will be saved to the smartphone in the directory “Local storage>Device Storage>RTKFox-15D”. After finishing the settings, touch the button “Back”. All settings on this page will be saved.

3. Now the device performs as a base station. The location shown below is what you entered in step 2 above.

Please note GNSS antenna of the base station should be mounted where a 360° unobstructed clear view of the sky (at 10° angle from the horizontal) is available. And away from motors and high-power transmitters, such as telecommunication base stations and radar antennas.

Service of NTRIP caster

If you have two devices (RTK15D series products), you can configure one as the base station and another as the rover. Then use LOCOSYS’s free service of NTRIP caster to link them. Below is the information of LOCOSYS NTRIP caster.

| For base station| For rover| Remark
---|---|---|---
IP| 59.124.229.95| 59.124.229.95|
Port| 2101| 2101|
Mount Point| V8DM7C8z2cnD| V8DM7C8z2cnD| The user enters Mount Point named by himself. In order to work correctly, the name must be different from others. Mount Point of the base station and the rover must be the same.

After completing the settings, the rover can receive the correction data from the base station to get RTK positioning.
Please note the entered location of the base station must be the actual correct location of its antenna. RTK fix rate of the rover may decrease with the distance between the over and the base station.
Satellites Information
Satellite information shows the satellite’s signal strength and satellite number. The Upper left corner provides a combo box to switch rover or base satellite information. The histogram shows the signal strength in each satellite. The L1 satellite’s signal strength is shown by solid lines. The L5 satellite’s signal strength is shown by dotted lines. The number of “VIEW” means how many satellite data is received by RTK15D. The number of “USED” means how much satellite data is used by the RTK algorithm.

Track
To track position trajectory in a centimeter-level map. It’ helps you realize the distribution situation of fixed position point. Each point is a fixed position point. When you are in static status, you can see the point distribution like a circle around you.

Map: Open google Maps to display the current position on the map.
Mock Reset: Reset the android mock location.
