3.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.

SV1 User Manual
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.”
