LEVEL-2
ANTI-JAMMING
GPS Anti-Jamming Active Filter - The Time Firewall Subsystem
NTS-LEVEL-2 automatically recognizes and eliminates false GPS L1 C/A code send over 1575,42MHz frequency carrier. Simultaneously, it passthrough GLONASS 1598,06-1605,38MHz. It is dedicated anti-jamming active filter.
Device is a cyber-security class rack”19 (1U) mount device. It operates fully automatic (no setup configuration).
It includes 2x build-in GNSS receivers LEVEL-1 100% compatible to NTS-antenna. NTS-LEVEL-2 provides clean filtered GPS output directly to ELPROMA NTS-family servers. Device introduces +/- 15ns error. The cable delay can be compensated and stored.
