Speed Over Ground
Current GPS speed over ground in knots. The data is sent as ASCII characters. Note that two formats are
available, in order to support supersonic or subsonic operations: ssss.s or sss.ss
For example, if the speed over ground is 62.5 kts, the packet structure would look like:
[ 30 ] [ 36 ] [ 32 ] [ 2E ] [ 35 ] [ 30 ]
