I am struggling a little bit with integrating my RTK with Pixhawk4. Currently, I am continuing a project from students who worked on it for the last year. Therefore I am not sure which things I can change without messing up the software. From the following manual (https://docs.emlid.com/reach/ardupilot-integration/) it became clear how I can integrate the RTK module with Pixhawk. However, I cannot find the parameter “GPS_TYPE2” on my Pixhawk software. This parameter allows a 2nd GPS module on the Pixhawk. I tried finding the parameter via Qcontrol and Mission Planner but both did not give me this parameter. I tried implementing the full parameter list from (https://ardupilot.org/plane/docs/parameters-Plane-stable-V3.9.10.html) but I did not know how I can do this. However there are multiple parameters missing from my RTK.
After searching a little bit further I found a list of the exact parameters which were listed inside Mission Planner which can be found here: https://hamishwillee.gitbooks.io/ham_px4userguide/content/en/advanced_config/parameter_reference.html .
I am wondering if the wrong set of parameters is implemented into my Pixhawk or if an other type of software is used inside this Pixhawk. I am struggling for over a week now and I really want this to work. Could someone help me out?
