I would be inclined to steal the opentracks code, assuming that's licensing ok (and maybe ask if not), and align with geographiclib. I didn't really notice when opentracks got bigger...

Now you are just being rude. I didn't say that the US national datums were unimportant for US users and surveying. But it is all outside the scope of GPSTest,...

As a first step, how about having the code in a library where the calls just error at first (no data), and then if you manually invoke "get the file"...

I wonder if you download the EPSG dataset and look at the SQL if you will find a URL. Also check the latest roj and proj-data. NGA has reorganized their...

hey bot still valid!

Bordering on pedantic, but the Android API does not provide "WGS84 Altitude" -- it provides WGS84 Height above Ellipsoid. The other height reference is "WGS84 Orthometric Height" often called AMSL,...

It strikes me that DTM and looking into local datums is a red herring. Everything I've seen indicates that GNSS chips in Android phones operate in WGS84. I have not...

If this is about the phone not GPSTest, that's fine, but perhaps would be good to edit the issue title to "Samsung A71 GNSS receiver has strange/wrong output". As it...

It seems @vkbellis has already done this, more or less confirming that the HAE computed off-phone by raw observables matches the HAE inferred from the phone's NMEA ortho height and...
