Is there a way to be able to arm when the GPS is not used? I want to demonstrate Mission Planner and ArduCopter indoors where I will not get a GPS fix. I want to ARM and DISARM so folks can see the states on the HUD. However, I cannot ARM because it complains of having no 3D fix - even though I configured MP/AC to disable the pre-arm checks. Please advise. Thanks, Paul
@philip i am using latest mission planner 1.3.66 and arducopter 3.6.8. i was trying to connect here 2 GPS via can protocol for that i have switched here 2 from i2c to can and followed your steps. but mission planner couldn’t detect the GPS and no GPS lock also.and here 2 led always cyan blue light blinking (both green and blue partially) .
QGC shows no GPS fix, i have enable all the GPS parameters (both the GPS enable but has connected only one … Can someone tell me how to get GPS fix in pixhawk 4 module. I am using the GPS module that comes with pixhawk 4. 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.
Just do MP–>Flight Plan–>MP Tool–>Prefetch by doing Alt+select area (while PC is connected to Internet). This will save the map in C:\programdata\mission planner\gmapcache. Now take the same laptop/PC to selected area (where there is no internet). Open Laptop/MP and connect to Pixhawk via Mavlink. MP will automatically load gmapcache map
The autopilot (Pixhawk etc.) should be housed within a case (which includes foam over the barometer) and should be mounted with the white arrow pointing directly towards the front of the vehicle. It should be placed close to the center of gravity of the vehicle (both horizontally and vertically). Generally this means it should be placed within
Connect the LiPo battery. Connect the autopilot to the Mission Planner using a USB cable or telemetry. Open the Mission Planner’s Initial Setup >> Optional Hardware >> Motor Test page. Increase the “Throttle %” field and push each of the “Test motor” buttons to determine what percentage is required for each of the motors to spin.
An Extended Kalman Filter (EKF) algorithm is used to estimate vehicle position, velocity and angular orientation based on rate gyroscopes, accelerometer, compass, GPS, airspeed and barometric pressure measurements. The advantage of the EKF over the simpler complementary filter algorithms (i.e. “Inertial Nav” or DCM), is that by fusing all
Installing APM Planner 2. APM Planner 2 is a ground control station based on the Qt cross-platform development framework. Currently it runs on Windows, Linux, Mac OS X. For platform-specific installation instructions, see the links below: Windows. Mac OSX.
Mission planner gimbal settings were removed. This would allow pan and tilt. Since upgrading to 3.5 its all gone wrong! As the parameters have changed I am not sure if the SBUS option will work. I have gone back to putting tilt on AUX1 and configuring mission planner camera gimbal, Sero9 for tilt and Input Channel set to 8. Nothing happens. The bad thing is, that it also loses the GPS signal in Mission Planner. I took a look at the "Full Parameter List" in Mission Planner and saw, that I can change the GPS protocol to NMEA. As this gave me stable and good signals in u-center, I configured the M8N again in u-center to the out protocol NMEA with a baudrate of 38400 at 5Hz
Mission planner screenshots. Mission Planner Settings for DO_JUMP command ¶ In the example above the vehicle would fly back-and-forth between waypoints #1 and #2 a total of 3 times before flying on to waypoint #4. MAV_CMD_JUMP_TAG¶ Supported by: Copter, Plane, Rover.
Vehicle: normal setup for serial GPS (GPS_TYPE = 1) or DroneCAN GPS (GPS_TYPE = 9) Attach RTK GPS via USB to PC running Mission Planner or QGC. You first must “survey-in” the GPS, in Mission Planner. After the GPS is attached to the PC, start Mission Planner, enter the COM port to which it is attached and press “Connect”.
When Mission Planner reports NO GPS it means there is no gps. That could be a defective GPS or a bad connection to the GPS. No fix means it has not received enough satellites or a good enough reception to get a 3D fix and establish location but it does “see” the GPS.
