Dead Reckoning
Dead Reckonding when turned on gives APRS-SCS the ability to continue to move
moving Symbols across your map with out receiving any more Position Packets
from these moving stations. APRS-SCS is able to do this because it takes the
Last known Course and Speed for the moving Symbol and givin the time that
has passed since the last position report was received for that station.
APRS-SCS is then able to guess where the station is now if its Course and Speed
has not changed.
The Dead Reckoning feature of APRS-SCS defaults to on.
Even if you are a registered user of APRS-SCS.
Moving stations call sign color is Cyan. Dead Reckoned stations call sign color is Green.
In other words stations with a green call sign are displayed at their Dead Reconed position.
Stations with Cyan Call signs are moving stations shown at there latest position.
