MA-802/GB NTP Server Network Time Server w/ 3 Ethernet Ports 30M/98.4FT Antenna Cable For GPS Beidou

MA-802/GB NTP Server Network Time Server w/ 3 Ethernet Ports 30M/98.4FT Antenna Cable For GPS Beidou

Model Comparison:
- MA-801/G: For GPS time service
- MA-801/GB: For GPS and Beidou time service
- MA-801/C: For CDMA network time service
- MA-802/G: For GPS time service
- MA-802/GB: For GPS and Beidou time service
- MA-802/C: For CDMA network time service
- MA-812/GB: For GPS and Beidou time service

Attention: MA-801 series are desktop devices. MA-802 and MA-812 series are standard 1U rack devices.

MA-802/GB Advantages:
- This series with 1-8 optional Ethernet ports
- Standard rack type NTP server
- 100M Ethernet port
- Easy installation
- Stable and reliable performance
- 7*24 hours maintenance free
- Simple debugging and easy to use
- Self-service time for power failure. Built-in 3V button lithium battery, service life> 5 years (depending on models, configuration will be changed)
- When satellite loses contact, it can still be synchronized. NTP server has its own master clock function, and client-side can be timed after the satellite loses lock
- Can process 10,000+ client requests per second

Features:
- Support cross network segment. Access timing across network segments through 3-layer switches or routers.
- Internal precision reaches NS level. Built-in high-precision constant temperature crystal oscillator to ensure punctual accuracy.
- High-precision network timing. The 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.
- Network port is independent CPU. A single network port can process timing requests up to 8000-10000 times per second. MA-802/GB can support 1-8 network ports (optional ports), which is suitable for multiple network segment isolation environments. The main network port can be set to secondary NTP mode (incarnate as an NTP client).

Product Parameters:
- Time source: For GPS satellite, Beidou satellite
- Network protocol: NTP v1.v2.v3.v4 (RFC1119 & 1305), SNTP(RFC2030), (RFC1321), DHCP(RFC2131), HTTP, IPV4
- Precision: Synchronization precision 1us
- Client accuracy: User terminal synchronization timing accuracy: 1-50ms (typical value of LAN)
- NTP request volume: 8000-10000 times per second for a single network port, expandable 1-8 network ports
- Number of clients: Tens of thousands of clients can be supported
- Signal receiving parameters:
* 72-channel timing GPS Beidou hybrid receiver
* Support single satellite time service window mode
* GPS receiving L1, C/A code signal-1575.42MHz
* Beidou 1, mode can choose pure GPS, pure Beidou or mixed modes.
* Tracking and locking sensitivity can reach -167dBm
- Power-off time: All series support RTC backup clock (even if the power is off, the time will not be lost)
- WEB management: The whole system supports WEB page device management, you can access it by entering the device IP, and you can view the real-time status of the device without installing any software
- Alarms:
* It sounds an alarm when NTP server does not lock satellite for a long time
* NTP server IP address conflict alarm
- Security: RTOS real-time operating system is adopted, and there is no risk of virus damage, data tampering or loss. Fanless and maintenance-free design guarantees long-term stable operation of the system 7*24 hours.
- Other parameters: The client can also be timed when the satellite is not locked
