[time-nuts] Symmetricom NTS-150 Network Time Server Report

Afternoon all, The NTS-150 arrived today from the e-place. Made a null-modem cable, fired it up, and eventually the LED went flashing green indicating GPS lock. However...it thinks it's the year 2001...a clear indication of the GPS rollover issue. Some googling indicates that while a

Good morning all, Spotted one of these on the e-place for $50 plus shipping and couldn't resist. I've got four other GPS-NTP servers already, so this really fits into the "nuts" portion of time-nuts. ;) Looking in the archive, only found one post on it dealing with firmware. I know it's a

[time-nuts] NTP Servers - RPi, NTP-Sec, Teensy 4.1, and one on the way from eBay

Good morning all, Several weeks ago, my Raspberry Pi (RPi) based GPS/NTP server quit working. I really can't complain, I want to say that it's been up, operational, and serving network time to my network for at least two years. I immediately rebuilt the installation from scratch on a new

Afternoon all, I finally got ahold of a UBlox F9T in the form of the RCB-F9T evaluation module. Got it talking to Lady Heather on an old Raspberry Pi, and everything is working, but the satellite table is blank. Just shows ".." in the PRN column, with AZ, EL, SIG, and DOPPLER blank.

Good morning all, Some people may remember the Arduino code I wrote for controlling and monitoring the TruePosition GPSDO I wrote in mid-2017. I've updated that code to include a couple of new things: * now gets the store LAT/LONG/ALT and displays it * adds an LED that lights up when STAT=0
