Hi all, I've just found an old anti-theft system (I think) for cars . It has a tyco electronics A1205 gps module. I've been unable to find any information about this module, other than it should be a 3.3V 12 channel GPS module with serial NMEA output. Does anyone have any informations about it?

Should have added. You get great documentation also and everything is well established and most likely will handle some 1024 week rollovers. The old stuff is quite annoying with respect to this. Regards Paul WB8TSL On Sun, Dec 14, 2014 at 11:05 AM, paul swed paulsw...@gmail.com wrote: Strongly

Hi Maybe a bit more on a timing receiver: GPS is (for some reason) better known for navigation than for timing. In navigation the receiver moves around a lot. In most timing applications, the receiver is stationary. When moving, the mathematical solution to the “where am I / what time is it”

kb...@n1k.org said: My guess is that there is no PPS out of the device. It would be very unusual if there was. Finding the NEMA output pin should be possible with an oscilloscope. At that point, a simple serial connection to the server is about all you need. Bring up the NEMA driver and it is
