AP-GTR1500 Embedded NTP Server with Internal GPS Time Receiver

AP-GTR1500 embedded NTP server with GPS time receiver hardware receives GPS time information from GPS satellite and performs the NTP(network time protocol) server service for network based application server which requires accurate time information like as CCTV NVR server.  Legacy GPS Time Receiver products only support RS232C Interface but AddPac AP-GTR1500 supports two(2) fast Ethernet port as well as dual RS232 interface for backward compatibility. AP-GTR1500 GPS NTP server terminal is easy to manage remotely and provides excellent scalability. This device can be applied to various real-time video applications such as video surveillance, traffic management and monitoring for disaster prevention

IP based GPS Time Receiver Terminal

AP-GTR1500 embedded GPS NTP server transmits GPS time information to network based application server which requires accurate time information via ethernet port. In local area network, this device transmits GPS based time information to application server like as CCTV recording serverby using NTP protocol.

Without GPS based time synchronization or NTP server, if time is passed after installation or in service, each application server’s time clock is mismatched comparing with GPS based real-time. Especially, in case of CCTV application, time mismatching should be solved between real-time and CCTV application server’s current time. 

AP-GTR1500 provides easy system cabling and Installation service by using LAN interface and internal GPS time receive hardware module.

In front of AP-GTR1500, there are LCD display for GPS time information and blue LAMP for device status. Also, there are two(2) fast ethernet port and console port. At the rear of AP-GTR1500, there is one module slot for AP-GPSR2 module. AP-GPSR2 module provides dual DB-9 RS232 interface port and GPS antenna interface port.
