Spectracom 8183 Netclock GPS Satellite Atomic Clock Receiver 10MHz IRIG-B 1PPS Includes Antenna and 120V Power Supply Photos show the actual item for sale Description The Spectracom NetClock/GPS Master Clock is a precise, traceable time provider. The NetClock/GPS receives and recovers time information from the Global Positioning System (GPS) constellation of satellites. The GPS constellation consists of 24 satellites placed in 6 orbital planes spaced equally around the equator and inclined at a 55-degree angle. This design assures reliable worldwide coverage 24 hours a day. Each satellite contains a redundant system of highly accurate and stable atomic clock sources. The satellite’s timing, orbital position and other system parameters are monitored and controlled by ground stations maintained by the US Department of Defense and US Naval Observatory. The NetClock/GPS Master Clock provides timing outputs accurate to within 100 microseconds of UTC. Standard Master Clock outputs include RS-232, RS-485, IRIG B/E and a one pulse per second. The NetClock/GPS is ideally suited as a Master Clock in all applications requiring an accurate and traceable time source. Typical applications include computer network timing, utility billing, financial transactions, public safety and transportation The clock comes with everything you need to receive accurate time from the GPS system. I am including a mag-mount antenna, and a power supply to get you started. A copy of the manual is not included, however this may be downloaded if needed. I placed the antenna and receiver outdoors (so that the antenna would have a full view of the sky) achieved time sync within a few minutes. I also tested with a professional grade outdoor antenna - the results of those tests are shown in the log files reproduced at the end of the listing. The basic indoor antenna is included to allow you to test it straight out of the box, but for a permanent installation an outdoor antenna with a full view of the sky is recommended. I usually have some suitable antennae listed, and a suitable downlead can be obtained from a cable fabricator. I have some related hardware also listed on eBay. The unit's home timezone and other parameters can easily be changed by using Windows Hyperterminal via the serial management port (serial cable not included). You will therefore need a computer with a serial port and appropriate cable if you want to change the unit's configuration. This is a very capable piece of equipment and you can find all functionality documented in the user manual. The included power supply is rated at 12V @1A and accepts 120V AC input. Alternatively, a generic power supply conforming to the spec below may be used instead (note the unusual polarity on the barrel connector): DC Input: 12 to 36 VDC, 20 Watts. Connector: Barrel, 5.5mm O.D., 2.1mm I. D. Polarity: Positive shell, negative center.
