The GPS module is OK. We reach GPS fix relative fast Fix Type "3D position", later it switches to "DGPS/SBAS aided 3D position" which is the best you can get without RTK capability.

The backup battery on the GPS module as reason of problems is a myth. The backup battery is only for faster GPS fix, not for better one.

No, I think, the GPS support is switched off by intention. Can you please double-check GPS setting in ST16?

In a relative early phase the parameter EKF2_AID_MASK is set to 0x20. That means, GPS is not part of the calculation. All following symptoms are related to this (no home position, GUIDED_ENABLED in MAVmode, reject Angle mode and so on).

In case Angle Mode is allowed, the parameter EKF2_AID_MASK is set 0x21=0010 0001 (bit 0 means use GPS).

I have compared two flights:
- With Angle mode: 00410, related sensor files 00356+357
- Angle Mode denied: 00468, related Sensor file 00410.

The following parameter setting are shown in the Sensor file 00356:
1504 00:01:07 COM_HOME_SET : Type: 6, Index: 134, Count: 802, Value: 0
1505 00:01:07 RTL_RETURN_ALT : Type: 9, Index: 610, Count: 802, Value: 35
1506 00:01:07 LNDMC_ALT_MAX : Type: 9, Index: 290, Count: 802, Value: 120
1507 00:01:07 RC_TESTPILOT : Type: 6, Index: 604, Count: 802, Value: 0
1508 00:01:07 EKF2_AID_MASK : Type: 6, Index: 165, Count: 802, Value: $21=0010 0001
1510 00:01:07 COM_LED_MODE : Type: 6, Index: 136, Count: 802, Value: $01=0000 0001
1515 00:01:07 COM_HOME_SET : Type: 6, Index: 134, Count: 802, Value: 0
1517 00:01:07 RTL_RETURN_ALT : Type: 9, Index: 610, Count: 802, Value: 35
1518 00:01:07 LNDMC_ALT_MAX : Type: 9, Index: 290, Count: 802, Value: 120
1519 00:01:07 COM_LED_MODE : Type: 6, Index: 136, Count: 802, Value: $01=0000 0001
1520 00:01:07 RC_TESTPILOT : Type: 6, Index: 604, Count: 802, Value: 0
1524 00:01:07 EKF2_AID_MASK : Type: 6, Index: 165, Count: 802, Value: $21=0010 0001
1533 00:01:07 COM_LED_MODE : Type: 6, Index: 136, Count: 802, Value: $01=0000 0001

And in contrast in Sensor file 00410:
1792 00:01:10 COM_HOME_SET : Type: 6, Index: 134, Count: 802, Value: 0
1793 00:01:10 RTL_RETURN_ALT : Type: 9, Index: 610, Count: 802, Value: 20
1794 00:01:10 LNDMC_ALT_MAX : Type: 9, Index: 290, Count: 802, Value: 120
1795 00:01:10 COM_LED_MODE : Type: 6, Index: 136, Count: 802, Value: $01=0000 0001
1796 00:01:10 EKF2_AID_MASK : Type: 6, Index: 165, Count: 802, Value: $20=0010 0000
1797 00:01:10 RC_TESTPILOT : Type: 6, Index: 604, Count: 802, Value: 0
1800 00:01:10 RTL_RETURN_ALT : Type: 9, Index: 610, Count: 802, Value: 20

1815 00:01:10 COM_LED_MODE : Type: 6, Index: 136, Count: 802, Value: $01=0000 0001

3920 00:01:44 EKF2_AID_MASK : Type: 6, Index: 165, Count: 802, Value: $20=0010 0000
3925 00:01:44 COM_LED_MODE : Type: 6, Index: 136, Count: 802, Value: $01=0000 0001

Maybe a PX4 Autopilot expert can say more about the GPS handling.
However, my eyes are directed to the ST16...

Thank you for your help. But how can I recheck the GPS settings? I've never done that. Mike.

I do not have a H Plus. I do not exactly know, how to switch the GPS. Isn't there something like "Switch off GPS" ?

When you boot up the controller and aircraft, click on the little white cog wheel in the upper right of the screen.

With the aircraft highlighted (green drone), scroll to the bottom under 'Advanced Settings' there is the 'Manual' button that allows you to turn off the GPS. Selecting this turns off the GPS. In my example you can see I am not in manual mode so GPS is On.

Update

To my previous post. It's been a while since I flew in manual and discussed all the nuances of the Plus but if I remember correctly, putting the Plus in 'Manual' essentially tells the software to not USE the GPS however - it is still on - just not being used for position holding.

I think there is somewhere else to literally turn off the GPS - will report back with what I find.

This is exactly what the parameter means: GPS will not used for positioning the drone. But it is always on, provides coordinates to telemetry and is used to compute distance between RC and drone. We have GPS sensor bit set, GPS is working, GPS fix is there, we have coordinates but will not use GPS data because parameter EKF2_AID_MASK exclude GPS data from computing attitude of the drone.
Those parameter settings probably come from ST16 flight mode app.

My firmware versions page.
This might be useful. Your system is on Build 829. I am not familiar with this build, but the notes copied below make it sound suspect.
Does anyone have any information on this Build? Especially information to either confirm or dispute the apparent bad review attached below.

Mike,
Do you know how your system came to be loaded with Build 829?

I just checked and now I'm remembering. I got one of the first H Plus models and that firmware had another page where you could literally turn off the GPS. Within a month of getting my Plus an update came out and after updating that choice was gone - I think. I just went through all menus and cannot find the GOS Off switch - only the 'Manual' switch.

I see @WTFDproject just made a post about an old firmware. that was what was on my H Plus when I got it that is the original firmware for the H Plus.

Thats it! Thats the second switch I was referring to. When I got my Plus - that is how my menu looked - that switch was removed in later firmware versions - it is not on my Plus anymore.

It is there, but very arbitrary. The drone and the ST16s controller stand side by side, and shows, for example, 5 m or whatever she wants. Only the height shows correctly - 0.
Did you try what will happen without camera?

@WTFDproject I am trying to remember all of the early stuff and then it hit me - I started a thread about the Plus when I first got it. That thread details some of the firmware and updates to the early Plus's. If you want to check it out and see if it makes any sense out of things HERE is a Link to that thread.

PS. In that thread I talk about the first update and it is the only update I ever did - here it is still to this day.

А я думаю, зачем же два переключателя GPS?

In the copter menu is a software switch about the GPS. Do you talk about it?

On mine, it is turned on. For sure my controller is with the last available update.

This switch should not prevent arming in angle mode. Here is night now. Tomorrow I'll check and write the result.

@Mike Halkin, are you sure, you didn't select in the menu the mode switch to be manual in the upper position instead of sport?
