GPS signal is very weak. Like trying to see a single 40W light bulb from space ! So in order to make it work well it is important to. a) keep antenna away from any source of interference (best to avoid all other electronics and even the main wiring as it also will create a magnetic field during flight)After completion, click on the CONNECT on top right corner of the window to connect the APM board to PC. Now it will show the Device as "Quadrotor". Step 2 - Calibrating Compass and Accelerometer. Now again go to the Initial Setup tab and click on Mandatory Hardware.
hey:) I have a setup on the quadcopter with dual RTK for position and heading using “simpleRTK2B Pro”, “simpleRTK2B lite” and “Pixhawk cube orange” with 4.2.3 ver. The correction is external and passes throw “Mission Planner” to the cube and then to the Ardusimple boards. I have encountered two issues: The “Mission Planner” is sending the message “PreArm: GPS 1: not
Upload scripts (files with extension .lua) to the autopilot’s SD card’s APM/scripts folder. If this folder does not exist, you can create it by setting SCR_ENABLE to 1 and rebooting. This folder can also be created manually on the SD card. If using Mission Planner, this can be done using MAVFTP. This mode requires communication between Ground Control Station (such as Mission Planner) and flight controller. In the Mission Planner Flight Data screen map, try right-clicking on a nearby spot and select “Fly to Here”. You will be asked for a guided mode altitude. Enter an above home altitude in meters.Also, using tera term and an ftdi cable, I can see NMEA messages, that indicate a 3D fix with an HDOP of 0.9. However, I’ve never seen better than a 2D fix on Mission Planner, and the HDOP is always reported as “100.0” with about 10 satellites. These are my parameter values: GPS_AUTO_CONFIG 1 GPS_AUTO_SWITCH 1 GPS_GNSS_MODE 3
