[time-nuts] Re: Seeking info on Ericsson NCD 901 56/1 devices

Kim,
This is great, thanks for sharing! The GPS 02's performance looks rather impressive, with 65 channels. I ordered a couple of the GPS 03s as well. It looks like these are mostly plain NMEA strings, but with some additional $PERC strings thrown in that are unique to the Ericsson protocol, which is lightly documented in this paper:

Seems like a decent receiver. Looking forward to documenting it more. Reminds me a lot of the Nokia FYGM, which I have documented here: https://ljck.org/doku.php?id=nokia_fygm
