[GPS_Standard] Resolution T GPS receiver

[Roberto Barrios]

Hi Bob, Bert,

 

I've got one Resolution-T running on my VE2ZAZ standard. The datsheet says somewhere it's (3.3V limited) output is TTL compatible. Yes, some interfaces are pickier than others, but my PCB from Bert is working fine without further modifications.

 

I agree with Bob, this is a fine GPS timing receiver. Better specs, smaller, less power-hungry and with much more functionality than the older Motorola Oncores. The software for this receiver (DSPMON) from Trimble is great, but look for version 1.53, not earlier.

 

Regards,

Roberto Eb4EQA
