Overview
Essential GNSS Anti-Jamming Module - Dual Band, OEM Protected: L1/ E1+L5, Passthrough: L2
The OtoSphere-LightHouse Dual Band OEM is a compact, rugged and cost-effective non-enclosed OEM, dual-band, 2-element GNSS anti-jamming module designed for commercial ground, aerial and maritime platforms.
- Protects two GNSS bands simultaneously, any two of GPS L1/Galileo E1, GPS L2, GPS L5 and GLONASS G1
- Optional passthrough of up to two additional unprotected GNSS bands
- Optional direct path to a second receiver (unprotected)
- Software-defined, field-upgradeable anti-jamming algorithms with null steering
- Real-time jamming detection, status and power-level monitoring via UART
- Compatible with modern and legacy GNSS receivers with a physical RF input
- Non-enclosed module for integration into your own platform or housing
- Designed for non-military platforms and applications
