GPS Real Time Orbit Determination and Initial Results Analysis
On the basis of sliding the observation spans and combination of multi short arcs' normal equation,a new method of precise real-time GPS satellite constellation orbit determination is proposed.Based on the new method,about 70 IGS stations are used to estimate GPS real-time orbit product.The results show that the accuracy of real-time orbit is about 5 cm,equal to the accuracy level of IGS rapid precise orbit products.
