It is about twice the price. I'd have to say the Motorola Oncore UT+ is the easiest to use. All the connections are to 0.1" pitch male header pins so there is no need for solder. The UT+ sells for about $16 on ebay. The documentation is exhaustive and complete and written in "standard English". And of course the UT is very accurate with a standard deviation in the PPS of about 49 nS. The newest version of this GPS is the M12M sold by Synergy Systems. It sells in qty 1 for $60 and comes with tech support from a US company and has PPS arcuate at the 2nS level. I'll buy this one next I don't think the dps18 comes even close to 2ns. Here is the data sheet. http://www.synergy-gps.com/images/stories/pdf/m12mt_brochure.pdf -- ===== Chris Albertson Redondo Beach, California _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
