In Mission Planner’s full parameter list or full parameter tree, set the FS_GCS_ENABLE parameter to: Disabled (Value 0) will disable the GCS failsafe entirely. Enabled Always RTL (Value 1) will switch the copter to RTL Mode. If the GPS position is not usable, the copter will change to Land Mode instead. Mission Planner: Live Compass Calibration Hold the vehicle in the air and rotate it slowly so that each side (front, back, left, right, top and bottom) points down towards the earth for a few seconds in turn.

NO FIX means that the FC can communicate with the GPS but it does not receive enough signal to establish a location. Installation links for some of the more popular GCS systems are provided below: Mission Planner (Windows, Linux, Android): Install Mission Planner This GCS is the most compatible and closely tracks new features and updates in ArduPilot. It is recommended for first-time users and power users alike. It functions best in the Windows environment. So now I am still getting “Prearm: Fence requires position” even though it seems as though I have a 3d fix. Here’s the Mission Planner warning, note my GPS status. I’m using two blended gps’s. I don’t understand why when I started using the two blended, the first gps always shows as “3d dgps” From ardupilot/AP_GPS/AP_GPS.h /// GPS status codes enum GPS_Status { NO_GPS = GPS_FIX_TYPE_NO_GPS, ///< No GPS connected/detected NO_FIX = GPS_FIX_TYPE_NO_FIX, ///< Receiving valid GPS messages but no lock GPS_OK_FIX_2D = GPS_FIX_TYPE_2D_FIX, ///< Receiving valid messages and 2D lock GPS_OK_FIX_3D = GPS_FIX_TYPE_3D_FIX, ///< Receiving valid messages and 3D lock GPS_OK_FIX_3D_DGPS = GP… hey guys, I have a Pixhawk cube orange with 4.0.3 and the GPS works only on CAN1. The GPS is attached and the parameters were changed to take the GPS input from CAN1 port but the carrier board doesnt detects a GPS it doesnt hold its position in position hold mode or loiter mode. Mission planner telemetry shows that there is 3D fix and locked but the copter doesnt hold its position. After Rectangular Missions Tutorial. Open Autel Explorer App, click on Misssion. In Misssion missions, waypoints, rectangles and polygons will be seen. If there are any saved missions, they will be shown in the Misssion history. Click on Rectangle Task Options. By default the item's location will be your phone's current gps location. Logical Serial Port to Physical UART Assignment. ArduPilot Serialx Port numbering is logical, rather than physical. Which UART or USART port is assigned to a Serial Port is determined by the autopilot’s hardware definition file. Serial Port 0 is always assigned to the USB port, but others can vary. Check its description page. I have a Rover with dual F9P GPS in moving baseline with a local base station feeding RTCM through mavlink configured for GPS yaw. The Current Heading is not updating to match the GPS Track, and the GPS Track is correct. Often during a mission the Rover icon in Mission Planner will be pointing 20-45 degrees away from the direction of travel. Any help is appreciated. 🙂 Parameter File udDXQwB.
