Hello,
I’m a bit new to GPS receivers. I’m reading all about sawtooth correction of the 1 pps output signal, on the ilotus M12M or M12+.
I understand that correction can either be hardware controlled or software controlled.
Does anyone make a low cost stand alone board to carry out this correction?
I.E something that takes the raw 1 pps and serial data from the GPS receiver and produces a cleaner 1 pps output?
I’ve seen that the peak to peak jitter is reduced from something like 27 ns to < 10 ns.
Is this a reduction of just the jitter, or is the actual accuracy to UTC also improved by this amount.
Regards
Steve Jones
