Dave, I would suggest using the GPSD project. The software is aware of, and corrects, various quirks and gotchas in GPS devices.
You can use anything from polling JSON over telnet to a C API, and it will reliably report the current mode, precision, etc. Please see the 'status' and 'mode' messages here: https://gpsd.gitlab.io/gpsd/gpsd_json.html#_tpv And the good news is, the authors of the software are on this list :-) -- Sanjeev Gupta +65 98551208 http://www.linkedin.com/in/ghane On Wed, 22 Jun 2022 at 21:23, Dave via time-nuts <[email protected]> wrote: > I am using a NEO-6M to provide a PPS signal for an experiment but I need > to know when it is locked or not. > > Does anyone know if there is a way to find out from either the NMEA data > stream or via the proprietary protocol ?? > > At the moment I have it programmed to only provide a PPS signal when it > is locked (or nothing if not) and monitor > the PPS signal in the microprocessor, but it's not entirely satisfactory > and I need a better mechanism. > > Dave > > > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe send an email to [email protected] > _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe send an email to [email protected]
