Passive GNSS antennas are used to rebroadcast GNSS signals. Emergency and service vehicles are often parked inside and are not able to reliably receive GNSS signals. To provide the emergency vehicle with GNSS signals, GNSS repeater systems locate an antenna outside and then rebroadcast the GNSS signals inside the building. Therefore, when an emergency call occurs, the navigation system is immediately operational and can guide the vehicle to the specified location.
Key features include:
- Multi constellation coverage to maximize the number of observations available for position and time estimation (GPS, QZSS, GLONASS, Galileo, and BeiDou)
- Multi-signal and multi-band support
- Wide voltage range for broad receiver compatibility
- Strong electrostatic discharge immunity
- Rugged housing construction
