Hi Gary and other GPSD users, I’ve left my gpsd running spitting out debug | grep ntpshm for a while; GPSD is accepting the PPS leading edge consistently every second, however I still get this afte

Yo Andrew! What is the GPS module. I'll try to find documentation for it. So gpsd is working fine with PPS for you at 1Hz updates, but not at 10Hz updates, all else being equal? And you see gpsd PPS

Heya Gary, I ran it at 10 and grepped for PPS|NTP. Nothing of note is output at 10Hz. Same module at 1Hz NMEA has PPS detected. I have it on a USB FTDI chip’s DCD pin. I see DCD blinking at 1Hz usi

Yo Andrew! Nope. Is it really outputting PPS 10 times a sec? Not much point to that. Yup. I'm looking at the data sheet. It says 1PPS, not 10PPS. So I suspect your rpboelm is eleswhere. What version

Hi chaps, I have a 10Hz GPS module with 10Hz NMEA sentences, and PPS doesn't seem to be picked up. Has anyone tried this? I only see workarounds for 5Hz GPS in the code. My module is an Adafruit Ulti

Hi Gary, thanks for the reply. My local clock is set pretty close to correct (though it’s also setting itself from NTP linked to GPSD via SHM). Actually, |grep ntpshm shows that gpsd is feeding tim

Yo Andrew! Well, gpsd is happy with the PPS from the GPS. Is you local clock already set to something close to correct? It looks like you have no local time, which gpsd needs. RGDS GARY -- Gary E. Mi

Yo Andrew! Looks like your GPS does not have a lock. PPS just tells you the top of the second, not which second. That must come from the NMEA. Do you have a good view of the sky and a 3D fix? Hint: u
