[Bug 1426307] Re: location is inaccurate

 

Sorry for my poor English.

There is a way to view Satellite information.

https://wiki.ubuntu.com/Process/Merges/TestPlan/location-
service#Forensics

Execute this command in terminal

ubuntu-location-serviced-cli --bus system --get --property
visible_space_vehicles

Visible space vehicles:
	(type: gps, prn: 5, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 41 deg, elevation: 186 deg)
	(type: gps, prn: 13, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 74 deg, elevation: 24 deg)
	(type: gps, prn: 15, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 50 deg, elevation: 310 deg)
	(type: gps, prn: 17, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 8 deg, elevation: 119 deg)
	(type: gps, prn: 18, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 8 deg, elevation: 321 deg)
	(type: gps, prn: 19, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 6 deg, elevation: 58 deg)
	(type: gps, prn: 20, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 52 deg, elevation: 267 deg)
	(type: gps, prn: 21, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 5 deg, elevation: 297 deg)
	(type: gps, prn: 24, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 23 deg, elevation: 257 deg)
	(type: gps, prn: 28, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 51 deg, elevation: 67 deg)
	(type: gps, prn: 30, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 24 deg, elevation: 57 deg)

I think snr: 0 is the signal range. I'm in home, so all satellites have
signal 0, but almost I can view satellite information.

If I disable Here positioning the command output is always empty:

Visible space vehicles:
<empty>

So it seems aGps is performed by Here. Without aGps it takes about 10-20
minutes to fix. My old Android Samgung Galaxy S+ without Wifi nor Sim
takes this time to fix.

Is it possible to use information from the command in apps to show
total/used in fix satellites? It would very good.
