I am working on a project that has distributed sensors on an RF network and need precise timing so I can correlate the different events. I decided that I would time stamp the events using clock cycles after the last pulse per second (PPS) from a GPS receiver. The distributed nodes will report back to the main station the number of clock cycles since the last PPS and what time that PPS came in at, at least that makes sense to me.
Like anyone else I need to keep the price down on the system and paying a lot of money for a GPS receiver or GPS Arduino shield will not keep the price down. I went to Mouser.com and found the Maestro GPS shown in this link http://www.mouser.com/ProductDetail/Maestro-Wireless-Solutions/A1035-H/?qs=sGAEpiMZZMsa9w4dmI1JYEv5hDt7Ew5Y a fully functioning GPS with PPS output for only $20.63 in single quantities. I bought one and designed a simple breakout board for it and sent that off to Osh Park for fab.
I probably should have asked this before ordering and fabbing, but does anyone here have experience with Maestro's GPS receiver? This Maestro is not the Maestro model of Magellan. After I get the breakout board assembled and running I will report my experiences as this seems like a great price for a GPS receiver with integrated antenna especially if they work good with little fuss.
