Hello everybody,
I recently created my own GPS board for the Lassen IQ Gps module. After getting it rigged up and connected to my computer I got me some data! I was so amazed. No magic smoke was lost and all the components(-1 blue LED) worked! Within a few minutes of sitting outside under a night sky I even got some actual GPS data! NMEA strings, I was so happy.. That is until I put them into google maps.. My Lat/Long seem to be off.. Not very far off mind you, but off. I appear to be several(~30 miles) SW of my actual position. I don't really feel comfortable giving out my GPS location so suffice it to say: I'm getting data. I'm tracking 4,er 5, satelites and my GPS fix is "1"(See full NMEA string below). Anybody have an suggestions?
NMEA STRING(Minus GPS Lat/Long ofcourse) reported by GPS
$GPGGA,020637.00,XX194774,N,0YY35.2122,W,1,05,1.86,00055,M,-031,M,,*5C
Derived position:
XX.194774N
YY.352122W
Actual Position
XX.324286
YY.5868543
(Note, XX is the same, YY is the same so the GPS Data is in the Ballpark)
(Note 2, I just tried reseting the module, I removed both main power and battery power and I got the exact same results)
