A less intrusive way is to run: ubuntu-location-serviced-cli --bus system --get --property visible_space_vehicles
which gives you all the visible gps satellites: Visible space vehicles: (type: gps, prn: 2, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 23 deg, elevation: 235 deg) (type: gps, prn: 5, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 54 deg, elevation: 291 deg) (type: gps, prn: 6, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 1 deg, elevation: 197 deg) (type: gps, prn: 7, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 61 deg, elevation: 69 deg) (type: gps, prn: 9, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 28 deg, elevation: 91 deg) (type: gps, prn: 10, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 49 deg, elevation: 161 deg) (type: gps, prn: 13, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 27 deg, elevation: 272 deg) (type: gps, prn: 16, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 7 deg, elevation: 23 deg) (type: gps, prn: 20, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 65 deg, elevation: 199 deg) (type: gps, prn: 28, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 11 deg, elevation: 155 deg) (type: gps, prn: 30, snr: 0, has_almanac_data: 0, has_ephimeris_data: 0, used_in_fix: 0, azimuth: 73 deg, elevation: 163 deg) In addition, you could also run a standalone, cli-based gps test case (please note that you need to restart your device after having run it): phablet@ubuntu-phablet:~$ sudo GLOG_v=1000 GLOG_logtostderr=1 ubuntu-location-serviced-cli --bus system --test The test will try to acquire a fix from GPS only 3 times from cold start, and print out diagnostics together with a summary containing the mean/std.dev. of time to first fix. You will receive example output like: http://pastebin.ubuntu.com/10729507/ Hope that helps, Thomas On Fri, Apr 3, 2015 at 11:35 AM, Thomas Voß <thomas.v...@canonical.com> wrote: > Hey there, > > glad to hear you like the phone.
