[time-nuts] Trak 8810 GPS station (Rb GPSDO)

[Jean-Louis Oneto]

Hello,
I'm looking for information about a GPSDO built by Trak Systems sometime 
around 1990 under the reference 8810 which include a Magnavox MX 4200 GPS 
unit and an Efratom Rubidium Oscillator FRS-C, 10 MHz, Part no. 814-100-1, 
S/N 1049, Date code 8649.
I found the manual for the Efratom FRS oscillators, even if this part number 
doesn't fit the part numbering given in the manual.
I have more problem with the GPS receiver. Till now I only found the NMEA 
proprietary sentences descriptions. I'm not sure if it will pass the GPS 
week rollover (aka y2k bug), since the unit was out broken since a long 
time.
And I found strictly no information on the Trak 8810 itself.
Every piece of information will be very welcome!
Thanks in advance,
