U2 using gps without 1pps

"Colin XSD" #1474 开云体育 I think that would be ideal Hans. If the 1pps is available use it, if not use the NMEA data to auto correct the Frequency Reference. I doubt that is a simple task but it would allow use of a greater variety of GPS modules (& even Bluetooth units, if a Bluetooth Module is fitted). ? ? 73, Colin M0XSD. ? toggle quoted message Show quoted text From: Hans Summers Sent: Monday, July 1, 2013 1:53 PM To: QRPLabs@... Subject: Re: [QRPLabs] Re: U2 gps timing data ? All: ? You are all correct though: I should make the software so that if the 1pps signal stops for any reason, the system keeps time with its own internal oscillator, the same way as when GPS is off. One more enhancement for the list :-/ ? 73 Hans G0UPL ?
