GPS satellites when the device (GPS timing products, the Beidou satellite clock devices, power time synchronization) is a device Standard Time Jinan Wei Shang Electronics Co., Ltd. developed the application of GPS technology timing display and send the device to the United States Global Positioning System ( GPS) as a time reference, can simultaneously track 12 satellites, right when accuracy 0.1μS. Products using surface mount technology production to high-speed chip control, with high accuracy, good stability, strong function, no accumulation of errors, weather and other environmental conditions without geographical restrictions, cost-effective, simple operation, maintenance-free characteristics, suitable unattended. W9006B type of GPS satellites when the device has two-way RS232 serial signal, two-way RS422 / 485 serial signals, one-way TTL pulse signal, 7 air contact pulse signal, when you can adapt to the needs of a variety of different devices, widely used in electricity, finance, communications, transportation, broadcasting, security, petrochemical, metallurgy, water conservancy, national defense, health care, education, government agencies, IT and other fields. Unique features of the device when a GPS satellite. Embedded industrial motherboard, embedded operating systems; 2. When the client network to provide multi-functional school software; 3. Dual Ethernet ports, support NTP protocol; 4. No hard drive, shock-proof design, the system is stable and reliable; 5. TV display output can be set to display the page, scroll subtitles. As the picture may be broadcast during television programs off the air; 6. When the client network to provide multi-functional school software; 7.12-channel GPS satellite receiver, lock quickly; 8. Built-in high-stability TCXO, the annual drift of less than 1ppm, provide extremely high accuracy of automorphic; 9. You can set the delay to compensate for transmission delays, or aligned with CCTV time, before and after the range 4s; 10.1U 19 standard chassis, year, month, day, week, lunar calendar, hours, minutes and seconds display; 11. Large capacity battery, in the case of main power failure, but also output code 480 hours; 12. GB embedded time code television signal output; 13. When the output interface RS-232 or RS485, can be used for sub-clock school, when the school computer network, transmission distance a few hundred meters to several kilometers (without relay); technical indicators on the device when a GPS satellite. GPS receiving antenna Antenna Environmental requirements: Operating temperature: -45 ℃ ~ 85 ℃; Storage temperature: -50 ℃ ~ 90 ℃; Humidity: 100%, condensation; volume: φ96 × 126mm. 2.
