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
I might be out of turn here but isn't the PPS output still 1Hz regardless of the NMEA output frequency ? I did noticed when using the Adafruit module it seems to fire PPS on both the rising and falli
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
Yo Andrew! How do you know it is coming if you can't see it? What RS-232 pin is it coming in on? Have you tried high debugging levels in gpsd to see hat gpsd is seeing? Yes, applied a long time ago a
Yo Jamie! I also have one Adafruit handy. Your question is very similar to another one also asked today. I thought I knew the answer for when gpsd already owns the GPS device: pi3 ~ # gpsctl -x '$PMT
I am following up on the 2013 thread that Andre and Gary had regarding getting 10 readings a second (http://lists.nongnu.org/archive/html/gpsd-users/2013-09/msg00037.html). I am also using the Adafru
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
Hi Gary, gpsd users, I still can’t get a PPS good from GPSD even though the GPS unit has had a continuous fix for more than a week: gpsd:RAW: PPS pps-detect on /dev/ttyUSB0 changed to 1 gpsd:INFO:

Yo Andrew! [...] 19 seconds of 3D is not gonna give you much PPS. Are you sure you are using the '-n' flag? RGDS GARY -- Gary E. Miller Rellim 109 NW Wilmington Ave., Suite E, Bend, OR 97701 address@
Hello Gary, Yep, it has a great lock with 14 satellites detected (3D DGPS fix with SBAS satellites). Have a clear view of the sky with an external antenna. Attachment: smime.p7s Description: S/MIME c
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
Yo Anthony! Well, technically it is no longer a Pulse Per Second, but there are devices, like the Gamin 5Hz, that have the option of 5 pulses per second. gpsd just uses the first one. RGDS GARY -- Ga
Yo Kashyap! Good luck with that. 100mph is 44.70 meters per second. GPS receivers do not do well at that speed. u-center is winblows, we don't do windows. Use ubxtool instead. gpsd is lightly tested
