Basic Operation
This part shows user some basic operations to start work.
3.1 Insert SIM card
SV1 supports network working mode. Open the cover and insert SIM card.
3.2 Charge the battery
SV1 is equipped with Type-C charger which support maximum 45w PD quick charge.
Fully charge the battery will take 4 hours typically. The battery indicator is
red when charging, will turn green when fully charged.
3.3 Measure antenna height
To get correct elevation value, we need to know the correct phase center
height of the receiver. However, it is almost not possible to measure the
phase center directly. Normally, the software will read the receiver antenna
offset parameters. Once user input the measurement height, software will
calculate the phase center height automatically. Typically, there are two ways
to measure the height:
A: Slant height (to measurement line)
-
Centering and leveling the tripod on known point, then measure slant height from the ground point to the arrow at the side of the receiver.
B: Pole height (straight height to device bottom) -
Read the straight pole height.
3.4 IMU Sensor
STEC SV1 is integrated with powerful calibration-free IMU sensor to give
better experience in the real field work.
3.4.2 IMU Tilt Survey
To initialize the IMU sensor, receiver must be in Fixed solution.
In SurPad4.0 software, connect device and click “Device” -> “Device Settings”,
enable “Pole Tilt Correction” function. Then, go to “Survey” -> “Point Survey”
page. The software will guide user to calibrate the sensor.
- Input the correct pole height.
- Draw circle on the ground using the pole.
- Follow the guide and shake the pole back and forth for around 5-10 seconds or walk in straight line around 10 meters until it shows “Ready.”
3.5 AR Stakeout
STEC SV1 is integrated with high resolution camera to support AR stakeout
function, which give very useful guide for stakeout in the real field work.
