Abstract
Compass/Beidou satellite navigation system makes it possible for positioning using three frequencies for the first time. Single frequency pseudo-range measurement and multi-frequency combination pseudo-range measurement are introduced; single & dual frequency positioning accuracy of raw & smooth pseudo-range are analyzed; and the single point availability for different accuracy demands at Lintong station is counted. Results show that: the noise of the ionosphere free using triple-frequency combination is amplified as much as the one using dual frequency combination by eliminating only the first order ionosphere delay; and the amplification is 30 times by eliminating both the first and second order ionosphere delay; pseudo-range positioning errors less than 10 m takes up about 95 % for single & dual frequency pseudo-range; and the single point availability for 10, 15 and 20 m (both level and height errors) take up about 95, 99 and 100 % at the this station.
