GPS channel list:
Channel
Description
gps.latitude
Latitude
gps.longitude
Longitude
gps.height
Height above sea level
gps.status
0
Disconnected
no GPS module data (no connection)
1
No fix
unable to fix position
2
IMU
position is fixed using the built-in accelerometer and
gyroscope
3
GPS 2d
position is fixed in 2D space using GPS/Glonass
satellite data
4
GPS 3d
position is fixed in 2D space using data from GPS or
Glonass satellites
5
GPS + IMU
position is fixed in 3D space and corrected using the
built-in accelerometer (the highest accuracy)
gps.fusionStatus
0
Initialization
initialization and calibration of inertial sensors
1
Fusion
the device is using inertial sensors to correct the
vehicle’s position
2
Suspend
temporary error of the inertial sensors
3
Disabled
error of the inertial sensors; they are not taken into
account when determining the vehicle’s position
gps.speed
Speed of the vehicle in km/h
gps.headingMotion
Direction of the vehicle motion. When the vehicle is skidding, the
headingMotion value will be different from the headingVehicle value.
gps.headingVehicle
The direction in which the vehicle is heading. When the vehicle is
skidding, the headingMotion value will be different from the
headingVehicle value.
gps.accX
The longitudinal acceleration (longitudinal g)
gps.accY
The lateral acceleration (lateral g)
gps.accZ
The vertical acceleration (vertical g)
gps.gyroX
The angular velocity of the vehicle’s longitudinal axis
gps.gyroY
The angular velocity of the vehicle’s lateral axis
gps.gyroZ
The angular velocity of the vehicle’s vertical axis
gps.noise
The average noise level of the satellite signal. The lower the value the
better
gps.numSatelites
The number of satellites used to fix position
