Antenna Tracker Build Thread

Racing Quads, Self-builds & FPV

Thanks Steve. I needed to use loads of holiday up so I have time to mess about.

If anyone builds this, I can give some help.

I just tested it in the back yard and it didn’t work! But I had the magnetometer configured the wrong way round (its the opposite to Inav for some reason). It follows my 5" now.

I’ll strap a camera to the tracker and try to get some video later. Hopefully tracking my quad or a plane.

There is a slight possibility that the mag needs to be slightly rotated a few degrees. I wont know until later.

Excellent, very interesting, if I do get the time I’ve got a one of two shelved projects that could work well with this… :thinking:

43

Why are the GPS wires not conceiled in the the 3D printed parts :thinking: :thinking:

44

Poor planning. They will be on the final build which will have full 180 tilt :+1:

45

Did you put in the declaration

46

I put in 90 CW flip. I’m not sure if I can put in, say 95 etc?

// Select compass declination. Consult http://www.magnetic-declination.com/ to check your zone declination value.
#define Compass_Declination -0.34

48

Yes I have done that for the uk. But I think I may be able to enable a debug line to check with a compass

49

I’ll do a proper check at a field where there is no interference.

Struggling to get it talk to my self built Bluepill drone

Is the tracker the ap or is the bluepill?

53

The tracker is the ttgo and I was hoping it could receive the telemetry from the drone (Bluepill)

54

There is no push button on pin 12 (pulled down to gnd)? Are you using a gps and mag?

55

Did try one but made no difference

Yes using gps and mag

Having problems myself
My mag was the wrong way round and the pan servo back to front. Easy fix.
But the latest crossfire fw doesn’t give altitude as far as I can see unless I try to find it. Altitude is available on fw 4.11, but the mavlink is not stable.
I’m going to reload the latest fw and try to find the altitude.

Back in the days, I had to set my tracker facing magnetic north, once the tracker had enough GPS, then set that position as the zero heading which tied GPS and Magnetic North.

Here is my first attempt at getting this to work……I abandoned it in the end as I spent too many a weekend at it instead of going “shopping”….:rofl:

Wrong video but I’ll leave it for your entertainment…:grin:

I have altitude and heading on my crossfire now with the latest fw. But still not on the tracker. Gumble

…but you are getting there…:clap:
