What is the accuracy of Doppler locations?
Location accuracy varies with the geometrical conditions of the satellite passes, the stability of the transmitter oscillator, the number of messages collected and their distribution in the pass. This means in particular that a given transmitter can have locations distributed over several classes during its lifetime. Classes for which accuracy is estimated and related values: – Class 3: better than 150 m on both axes, 250 m radius – Class 2: better than 350 m, 500 m radius, – Class 1: better than 1000 m, 1500 m radius – Class 0: over 1000 m, 1500 m radius These are estimations at one sigma.
