My own experiences with Sklyine tracking have been quite positive. A lot of our flying is ridge flying and there is GSM coverage on many parts of our ridge.

But I have a question about this protocol. If the glider goes out of range for part of the flight, then returns to within range of a GSM tower, will Skylines show a break in the flight, or will the protocol cache and then send the missing track points? If the the latter is true (or could be implemented), then even if there is only partial GSM coverage, you will still get "pseudo live" tracking. Ie the Skyline site will get updated whenever the glider passes through the coverage area of a cell phone tower. If there is coverage at the landing site the scorer would have access to a provisional track before the glider has come to a standstill. Even if the glider outlands, there is a good chance that there will be GSM coverage at the outlanding site, or at least at circuit hight above the field. Thus the scorer could have the pilots trace before his crew have confirmation of the outlanding.
