Wrong timestamp for GPS location.

Odpad Android

I turned on continous tracking every 5 minutes between 15:49 and 16:48 (Poland, GMT +2). On the web page in GPS Coordinates I can find both GSM and GPS coordinates. Those for GPS Source have wrong timestamps, they should be 1 hour younger. Because of this track on the Locator Map has no sense.

Here goes my coordinates:

  1. 13.6.2014 16:37:27 GSM 50°19’15.973" 18°41’39.130" 33 meters
  2. 13.6.2014 16:03:57 GSM 50°15’56.394" 19°0’58.405" 50 meters
  3. 13.6.2014 15:57:21 GSM 50°15’55.735" 19°0’58.591" 59 meters
  4. 13.6.2014 15:52:21 GSM 50°15’55.829" 19°0’58.242" 60 meters
  5. 13.6.2014 15:49:36 GSM 50°15’55.735" 19°0’58.591" 59 meters
  6. 13.6.2014 15:48:32 GPS 50°19’14.603" 18°41’39.728" N/A
  7. 13.6.2014 15:42:51 GPS 50°19’17.403" 18°41’39.158" N/A
    8.13.6.2014 15:32:44 GPS 50°18’58.666" 18°41’41.944" N/A
  8. 13.6.2014 15:27:43 GPS 50°18’19.333" 18°44’24.76" N/A
  9. 13.6.2014 15:22:46 GPS 50°17’40.785" 18°46’15.540" N/A
  10. 13.6.2014 15:17:39 GPS 50°17’44.403" 18°49’46.468" N/A

The correct order should be like this:
6. 13.6.2014 15:48:32 GPS 50°19’14.603" 18°41’39.728" N/A
7. 13.6.2014 15:42:51 GPS 50°19’17.403" 18°41’39.158" N/A

  1. 13.6.2014 16:37:27 GSM 50°19’15.973" 18°41’39.130" 33 meters
    8.13.6.2014 15:32:44 GPS 50°18’58.666" 18°41’41.944" N/A
  2. 13.6.2014 15:27:43 GPS 50°18’19.333" 18°44’24.76" N/A
  3. 13.6.2014 15:22:46 GPS 50°17’40.785" 18°46’15.540" N/A
  4. 13.6.2014 15:17:39 GPS 50°17’44.403" 18°49’46.468" N/A
  5. 13.6.2014 16:03:57 GSM 50°15’56.394" 19°0’58.405" 50 meters
  6. 13.6.2014 15:57:21 GSM 50°15’55.735" 19°0’58.591" 59 meters
  7. 13.6.2014 15:52:21 GSM 50°15’55.829" 19°0’58.242" 60 meters
  8. 13.6.2014 15:49:36 GSM 50°15’55.735" 19°0’58.591" 59 meters

So coordinates no 6. have timestamp: 15:48:32 but in fact they were sent at 16:48:32 (GMT +2). I will try to set up another timezone at my phone to test it more.

BTW, I really like this app :slight_smile:

OK, I figured out: that is my phone and it’s GPS module. For Samsung ACE it works fine and for Spica it is wrong, both have custom ROMs. Maybe there should be option not to use GPS time for measurements?
