126.96.36.199 Accuracy• GPS Standard Positioning Service (SPS) Position:< 15 meters, 95% typicalVelocity: 0.1 knot RMS steady state• WAASPosition:< 3 meters, 95% typicalVelocity: 0.1 knot RMS steady state
I have a Gamin 18X to do some experiment with it in urban area
when i saw the manual
(http://static.garmincdn.com/pumac/GPS_18x_Tech_Specs.pdf), this GPS has an
accuracy in position of 5m in RMS, and an accuracy in velocity of 0.05m/s.
My question is: How can we have this accuracy in term of velocity?
(additional sensor inside the receiver, other signal used,....).
