GPS not working for Starling 2 Max
-
Hello,
Has there been any resolution on this? I have a brand new Starling 2 Max, with 5G and have let the drone sit for over an hour and no GPS.

@Kory4Drone sadly there has been no update.
@Zachary-Lowell-0 is there anything ModalAI can do to support? -

I have two drones and one does work so we havent chased the other one down much. I will be interested to hear what steps the team will have for you

How far away is the gps from the 5g hat? Also have you leveraged faraday tape around the fuselage of your drone so the signal for the gps doesnt get interfered. Odds are the issue isnt from the 5g hat but from the USB3.0 port if you are leveraging. Multiple studies show there is quite a lot of interference from usb3.0 that can disrupt GPS - the solution for this is taking faraday tape and wrapping it around the right spots to cut the signal:

@Zachary-Lowell-0 I don't know if there is another way to mount the 5G board (see picture - we sticked the antennas to the arms in the meantime).
.We assumed since all of the components are official ModalAI products, that they would work together.

@Bernhard When we released the 5G version of the Starling Max we also moved the GPS to the back of the drone and specified smaller LTE antennas which those landing gear were designed to fit. I'll reach out to you via PM regarding updating your Starling Max.
We just discovered a source of EMI which is the cable running to the optional Lepton sensor socket. For a number of reasons we've not offered Lepton as an option of Starling 2 Max yet so you can safely disconnect the 8-pin JST SH connector on the front left side of your camera breakout board next to the barometer cap. This will improve GPS performance. Please see picture below.

@James-Strawson is this sensor on the sentinel as well?
@groupo It is not on Sentinel.

@James-Strawson sadly that did not help.

@James-Strawson, @Zachary-Lowell-0 can we expect an update in the near future?

@Bernhard @James-Strawson @Zachary-Lowell-0 @Alex-Kushleyev @nuallaino
I have a brand new Starling 2 Max (received 3 days ago), and I'm having the same problem described by nuallaino and Bernhard (no GPS even when outside for a long time).
My system info and results of px4-listener are pasted below.
I did unplug the Lepton 8-pin JST SH connector as suggested by James Strawson, but that had no effect.
Everything else seems to work fine (haven't tried 5G comm yet), but I'm hesitant to fly without GPS functioning properly, so at this point I'm stuck.
Any suggestions would be most welcome.
Thanks for your help !
