InertialMessages / RTSpeed

RT_Speed Calculated speed

RT_Speed: 128, 16 (0x801020 + unit id) (0x010)

Byte 0: Validity
Byte 1: Accuracy
Bytes 2-5: Combined speed (m/s)
Bytes 6-7: Unused
Combined speed resolution is m/s * 1e-5.
Accuracy resolution is m/s * 1e-5.

This is the 3D speed output from a combination of GPS and inertial signals. This value is always positive regardless of direction of travel. Accuracy is an approximation to the 1 sigma standard deviation of speed.
