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

  There is also another version of these Ericsson GPS receivers floating
around - this one is marked "GRU 04 01" - physical construction is very
similar, but this one appears to be manufactured by Trimble.



Operationally, it's almost identical to the GPS 0301 described earlier, and
produces mostly the same output, except that it has an extra
$PERC,GPpps sentence that the earlier model didn't.  From the look of the
board, it's using the same (or very similar) GPS module, but
with modified internal firmware so that it directly outputs the Ericsson
messages rather than having to have the STM32 to translate the output.
