1.   Alternatively, countries such as Britain could provide space hardware or equipment for ground stations.

2.   And a brief signal from his on-board emergency radio beacon was misinterpreted by ground stations.

3.   And after it reaches orbit, all communications with the satellite will be centered at a ground station, also built and manned by students.

4.   A satellite picks up the signal, which is unique to each boat, then a ground station receives it.

5.   Broadcasters can beam directly to the satellite, without having to pass through a ground station first.

6.   Each ground station in the WAAS system will use tracking programs to compare the exact distance to a GPS satellite with the range implied by its radio signal.

7.   Fifteen minutes after the launching, an EarthWatch ground station in Norway received a signal from space confirming that EarlyBird had separated from the booster and begun automatic operation.

8.   GM Hughes will provide equipment for a ground control station in Beijing, and train the Chinese operators of that facility.

9.   In contrast with cellular phones, which function only if a ground station is nearby, a satellite phone can be used almost anywhere.

10.   Instead they bounce the calls back from the satellite to a ground station, where they are transferred to a long-distance land-line to be completed.
