imei:XXXXXXXXXXXXXXXX, your IMEI tracker, this is position message 1206081637, UTC Date and Time : YYMMDDHHMM , not identified, always saw this one as empty F, F:Fix (GPS is locked and has position) L: Lost (GPS is unlocked) 193729.000, Time : HHMMSS.mmm Probably local time. Have you configured a time-zone ? I haven't and in my case this is also UTC A, not identified, always saw this one as "A" 1249.9238,S, 12° 49.9328' South 03816.1788,W, 003° 16.1788' West 0.01, speed in notch (nautic miles per hours) 303.36; This one is empty on my tracker. May be altitude ? feet or meters ?
Are you sailing ? This is in 1500 km west of Angola shores So definitively not 303 m height !
Edit moderator: Please do not quote the message just above. Thanks.
Hi barbudor!! Thank you very much!!
Unfortunately I'm not sailing... The position is wrong, and maybe you can help me. My tracker always send the same coordinates, all the time. Do you know how solve this?
Have you left the tracker out on open sky for a few minutes ? How are the leds flashing ? On my Coban TK102, the leds flash as below : - 1 sec period, half on, half off : powering up, no GSM network, no GPS - 2 sec period, 1 short pulse on : GSM network ok, but yet GPS satellites - 2 sec period, 2 short pulses : both GSM and GPS ok
Yes, this is very strange. I did several tests, but on GPRS always get wrong coordinates. A curiosity, the difference between the distances is about 60Km (by car)
Could you be more precise and give me an exact sample of both SMS and GPRS coordinates for the same location ? It may be a conversion error in the interpretation of the results.
