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
