Problems with GPS USB tongle - SkipperEarly - 2016-04-02 Have just received the GPS dongle. Inspector shows: $GPRMC,112742.00,V,,,,,,,020416,,,N*7F $GPVTG,,,,,,,,,N*30 $GPGGA,112742.00,,,,,0,03,2.49,,,,,,*59 $GPGSA,A,1,20,17,05,,,,,,,,,,2.68,2.49,1.00*03 $GPGSV,3,1,11,05,25,208,23,07,08,079,,08,05,024,,13,84,283,*7F $GPGSV,3,2,11,15,43,301,21,17,16,132,26,18,11,324,12,20,36,264,25*70 $GPGSV,3,3,11,24,13,267,,28,67,086,,30,36,074,19*46 $GPGLL,,,,,112742.00,V,N*49 but underneath in the detailed view only the Date/Time is shown, not Lat/Lon I am using English language setting but German-Austrian keybord setting. Have tried various language settings as I suspected the . vs , in the decimal setting to cause this issue but makes no difference. Any suggestions what I can try now? Thanks for help! should have added that I connected the OP output to various programs like OpenCPN but got no position reading. RE: Problems with GPS USB tongle - Vamonos - 2016-04-03 It appears that you don't have a "fix". Perhaps your GPS dongle doesn't have a good view of the sky. All of those empty fields, where you see commas next to each other, is missing data.

Should have noticed the many ,,,, myself but guessed the last few numbers to be the lat/lo already - mea culpa. BTW did not expect to take nearly 20 minutes to get a first-time-fix! RE: Problems with GPS USB tongle - Sailoog - 2016-04-03 If you are starting a GPS for the first time, or after it has been powered off for more than a few weeks, this is a 'cold start'; it needs to get a new satellite almanac to do its job. The satellites broadcast this information very slowly (at 50bps) on a fixed schedule, and it can take up to 20 minutes. More details. |
