GPS RF Switch
The GPS RF Switch is a programable, hardware-based standalone solution that protects PNT systems from vulnerabilities by isolating them from the RF signals coming from the antenna. During this time, the server maintains accurate time from its internal oscillator.
Since an accurate oscillator also drifts over time, the antenna can be reconnected periodically to allow the time server to calibrate itself.
- Real bi-directional isolation
- Programability for predetermined disconnection of antenna feed
- Remotely accessible for immediate disconnection or connection of GNSS
- Physical disconnection response time <10 ms
- GUI response time <1s
- Supports full L1 & L2 GNSS.
The ease with which a GPS/GNSS RF signal can be blocked or disrupted and the damage this can cause, has made every organization understand the importance of protecting GNSS systems.
Erroneous positioning, navigation and timing (PNT) information in any part of the infrastructure can jeopardize security and disrupt user service.
Most cyber-attacks on time systems are performed through RF signals entering time servers. One of the best ways to protect these systems is to isolate them by disconnecting their antenna, which mitigates exposure to GPS vulnerabilities such as GPS spoofing or jamming.
