Re: Light dead satellite

Lightsquared still provides satellite communications so I'd suppose their satellite still can be utilized in that role. Perhaps it might still be able to bring internet to remote places.

There's no GPS compatibility problem with the satellite to earth signals but the uplink from ground terminals might still be a problem for nearby GPS receivers.

The problem is a financial one .. can the revenue delivered from the satellite operations offset operating costs?

No, LightSquared's satellite is licensed for uplink in the 1626.5-1645.5 MHz and 1646.5-1660.5 MHz bands. GPS downlink frequencies are 1575.42 MHz (L1) and 1227.60 MHz (L2).

LightSquared is licensed for 1525-1544 MHz and 1545-1559 MHz for their _downlink_, but at that power level, it won't interfere with GPS.
