The GPS time server offers selectable time sources, including GPS, BeiDou, CDMA, IRIG-B code, Oven-Controlled Crystal Oscillator (OCXO), and rubidium atomic clock. Regarding timing accuracy, the precision is 0.1 μs for pulse and IRIG-B interfaces, 10 μs for serial ports, 1–10 ms for NTP/SNTP network timing, and up to 70 ns for the PTP (IEEE 1588) protocol. The device supports various network protocols, including NTP/SNTP (V1–V4), ARP, UDP/Time, ICMP, SNMP, MD5, DHCP, TFTP, and Telnet.
GPS reception specifications include a frequency of 1575.42 MHz; reception sensitivity of <–160 dBW (acquisition) and <–163 dBW (tracking); cold start acquisition time of less than 5 minutes; hot start time of less than 1 minute; and 1PPS pulse accuracy of ≤50 ns (or ≤100 ns). BeiDou reception specifications include 6 channels (or 16 channels); reception sensitivity of –157.6 dBW; cold start initial acquisition time of ≤2 seconds; and 1PPS accuracy better than 20–100 ns.
The device supports auto-adaptive 220V/110V AC/DC power input and features a dual-power redundancy design. Its operating temperature range is –20°C to +70°C (indoor unit) or –40°C to +55°C (outdoor antenna), with a storage temperature range of –40°C to +85°C. Reliability metrics include a Mean Time Between Failures (MTBF) of ≥150,000 hours (or ≥80,000 hours), a Mean Time To Repair (MTTR) of ≤30 minutes, and a service life of at least 20 years. Physically, the device utilizes a standard 19-inch rack-mount chassis (1U or 2U).
