Use for NTP server Time Source
8 December 2014
Summary: Purchased this unit to use as a GPS disciplined NTP network time server. Added a DB9 serial connector on end of cable, plugged into a Debian-based NTP server and I am in business with a stratum one NTP server for my local network. This unit has run 24/7/365 with no problems. Highly recommended for its 1 pulse-per-second output time output.
Summary: Using it to feed my local ntp time server. I'm using the automotive windshield mount and have it stuck to the inside of an east facing window with no problems. The cable was plenty long and I had no issues putting a serial connector on it. Worked right away.
Summary: I have purchased many of these units over the years, and have never been let down. It has always exceeded my expectations for accuracy and performance. I first purchased this unit many years ago for an APRS tracker in a vehicle, and it worked for years stuck to the roof of a vehicle. It is fully waterproof.
Summary: Here are the 5+ Star Ratings: * Triple Accuracy in time, position and elevation. * Simple instruction obtained from Garmin Site, easily implemented. * Works the first time it is plugged in (power up the GPS first) then your APRS Radio. * Supplies data to my Radio without setting the GPS unit. * Consumes negligible current draw. * Use the GPS' built-in Magnetic back or 1/4" screw attach easily to post or car roof. Good Pricing, an arm or a leg not required.
Summary: With a little bit of DIY wiring, this GPS can sent PPS signal via the DCD pin of an RS-232 serial port and provide precision time to NTP running on Linux or BSD. Currently, this is providing a sub-millisecond PPS lock and the GPS is inside the top floor of a multi-floor building. Great fun/hobby unit at a great price.
