Abstract

In the previous report (Isshiki, 2004b), theory and algorithm of a new dual frequency long baseline kinematic positioning method were discussed. In the theory, the wide-lane coordinates are used as a constraint for obtaining the correct L1 ambiguities by solving the ionosphere free equations. The effectiveness was verified by some numerical examples. A precise positioning for baseline of several hundred kilometeres are possible. In the present report, the effect of epoch interval and observation length is investigated by numerical calculations. The relationship between the positioning error and the baseline length is also discussed. Furthermore, an algorithm for the real time application is shown.
