I see quite a few clock designs use the PPS output from a GPS module (VK15E module in stock) to replace the crystal timebase when a GPS signal is available. I'm looking for a stable accurate 1Hz signal as part of a Picaxe based clock timer but trying to decoding anything else from the module is way beyond me!
Read varying reports and data sheets I've found but dont seem to cover it. Question is anyone know how accurate and stable is the PPS output?
Thanks
