Ken is about 1/3 of the way to Koyuk. He's transmitting solid but without sending any GPS data. Iridium satellites also can send position information so I modified the server to use Iridium position if there is no other GPS position available. Iridium's accuracy is +- some number of MILES compared to our normal accuracy of 6 feet.
The system will now use Iridiums location information as long as it is accurate to +- two miles and our normal GPS positions updates are unavailable. So he will show up again but not necessarily in exactly the right place.
I still have to create some method of indicating the position is a best guess. Other mushers may also appear slightly off course rather than not getting updated at all for a period of time.
This also only gives me position. Speed and heading cannot be calculated from Iridium data.
