GPS (Global Positioning System) provides the accurate location and timing information that mobile satellite terminals rely on. For satellite acquisition, GPS coordinates help the terminal to point correctly at the satellite, ensuring robust and stable connections. Accurate GPS timing is also vital for modems to synchronize with the satellite network, ensuring data is transmitted and received efficiently.
When these signals are disrupted or tampered with, it can lead to inaccurate positioning and timing, causing significant disruptions in communication. This is where GPS spoofing comes into play.
GPS spoofing is a malicious tactic where false GPS signals are transmitted to deceive a GPS receiver. This can cause the receiver to calculate incorrect position or timing information. In the context of mobile satellite terminals, spoofing can lead to incorrect satellite alignment, resulting in degraded or lost communications. It can also disrupt the network timing of modems, leading to synchronisation issues and potential data loss or loss of link.

Recognising the vulnerabilities associated with GPS reliance, we have developed our next-generation land terminals like the SCORPION, SCORPION-LITE and SCARAB allow operators to manually input location data directly into the system. This capability ensures that the terminal can still acquire the satellite correctly and maintain communication links without relying solely on GPS signals.
