GPS Test Successful From Outer Space

An anonymous reader writes: "AMSAT reports that the GPS experiment on the international amateur radio spacecraft AO-40 has undergone successful testing." A note on the site reads in part: "This experiment supplied and sponsored by NASA, is to determine if it is possible to get positional data outside of the GPS ring of satellites. There are two GPS receivers on AO-40, the A receiver for receiving signals around apogee and the B receiver for signal reception around perigee. ... A signal on the apogee receiver from about 52 Thousand Kilometres out with good signal levels has been received, further data is being gathered and those downloaded so far are being analysed. If this experiment goes the way I expect, it will revolutionise the way we use GPS in Space. Many future HEO spacecraft will be able to take advantage of GPS for autonomous navigation and stationkeeping." This is one of the most interesting applications of GPS technology I've heard about -- nice way to reuse what was intended as a terrestrial navigation aid.

    When a billion dollar gizmo goes splat will be that a GPS receiver from Europe failed to "convert seconds properly from the Metric System"

    The worst terrorist attacks in recorded history occurred just under three weeks ago, and you people are discussing a project supplied and sponsored by NASA to determine if it is possible to get positional data outside of the GPS ring of satellites, using two GPS receivers on AO-40, the A receiver for receiving signals around apogee and the B receiver for signal reception around perigee, which resulted in a signal on the apogee receiver from about 52 Thousand Kilometres out with good signal levels having been received, with further data being gathered and those downloaded so far being analysed, which will likely revolutionise the way we use GPS in Space, which may lead to future HEO spacecraft being able to take advantage of GPS for autonomous navigation and stationkeeping?!!??!

    My *god* people, GET SOME PRIORITIES!
