Basic Details
The Inmarsat & GNSS Repeater Solution is engineered with separate uplink and downlink paths for reliable indoor signal availability in hangar and bunker environments. The repeater supports RF input and output VSWR of 1:1.6, with total RF input signal handling up to -20 dBm on both uplink and downlink paths. The downlink path provides a noise figure of less than 5 dB, while the uplink path provides a noise figure of less than 20 dB. For antenna integration, the system uses directional RHCP antennas for Inmarsat coverage, with GNSS antenna configurations including an active SAW-filtered outdoor omni antenna and passive indoor omni antenna.
