MA-812/GB NTP Server Network Time Server + 30M/98.4FT Mushroom Antenna For GPS Beidou Time Service

MA-812/GB NTP Server Network Time Server + 30M/98.4FT Mushroom Antenna For GPS Beidou Time Service

Advantages:
* High-precision constant temperature crystal oscillator and large-capacity time backup battery make time more accurate
* GPS, Beidou hybrid clock
* Level 1 network time server
* Support 10000+ times of time service/second
* Cabinet installation
* 100M Ethernet port
* Punctual when power off

Features:
- Support cross-network segment. Cross-network access timing is achieved through a three-layer switch or router.
- Internal accuracy is up to NS level. Built-in high-precision constant temperature crystal oscillator ensures punctual accuracy.
- Realize high-precision network timing. The actual network timing accuracy can reach 1-50 milliseconds under different network environments.
- It can provide timing services for tens of thousands of clients. Realize 10,000 time service requests per second.
- Three Working Modes: Beidou mode: In this mode, the NTP server only receives Beidou satellite signals; GPS mode: In this mode, the NTP server only receives GPS satellite signals; Mixed mode (default): In this mode, the NTP server simultaneously receives GPS and Beidou satellite signals.
- High reliability. Hardware adopts imported industrial-grade chips and adopts low power consumption, fanless and maintenance-free design. Software adopts an embedded system, and there is no risk of poisoning, tampering, etc. The system can automatically detect working status, give corresponding prompts and automatically repair the fault, to meet your 7*24 hours time service needs.
- Mushroom Antenna: Gain up to -38dB. Using 72-channel parallel receiver. Tracking sensitivity -167dBm | Cold start sensitivity -148dBm | GPS L1C/A | Beidou B1. Multiple mode options: pure GPS mode | pure Beidou mode | mixed mode.
- Simple debugging. WEB management page: Login password authentication, you can view the real-time status of the timer, modify network parameters, time zone, etc. Client software: In addition to WEB management, we are also equipped with professional client software.
