[time-nuts] Motorola M12+ breakout board

2018-02-16 Thread Mark Sims
Besides the Furuno GT-8036 breakout board, I just did a layout for a board that converts the pinouts of Motorola M12+ compatible receivers to a 0.1" 9-pin header that (mostly) matches the Adafruit Ultimate GPS. The Adafruit ENABLE pin is repurposed as a DGPS RTCM corrections input and the

Strange item... it has an M12+ and a supporting board full of components. Protocol translation from 12-channel to 8-channel? The link to the PDF file returns a 404. On Fri, Nov 22, 2013 at 9:32 AM, Pascual Arbona Lopez p.arb...@securimar.com wrote: I am wondering if this is a sustitute of the

[time-nuts] Motorola M12+ or M12M questions

2009-07-07 Thread Martyn Smith
Hello, I have been asked a question from a friend and would like to hear what the time-nuts have to say about the M12+ and M12M GPS receivers. His questions were: 1) It would be great if you could outline the broad algorithm and bits of information that go into keeping the 1 pps aligned to

2) along with the gps time signal, information is broadcast to relate gps time to utc. whenever there's a step change in these corrections (such as on midnight 31/12/2008), how does the unit react? 2.1) in particular, how quickly does the time code reflect the change, and is the 1pps

Hi All, Has anyone been able to figure out the part number and/or measured the phase noise of the quartz oscillator on board the Motorola M12+T? This will be an interesting figure to see. Regards, Stephan. This is an ADEV+MDEV plot for the 100 Hz output of an M12+ in free-run mode
