Vehicle-borne tracking and position device is used to track LEO satellite. Because of the absence of the target which might be caused by cloud or zenith blind zone
the forecasting data will be used to acquire the target. While orbit prediction has serious errors
the target is always missed. Meanwhile
in its application to the vehicle-borne tracking and position device
due to the base of instability in the tracking process
it will result in significant difference between predicting data and tracking data
so the target will be not tracked rapidly. We applied tracking data to predict satellite orbits by improving Laplace method
and then corrected the error between Predicted data and actual measured data by interpolation method of Lagrange which improves the accuracy of prediction values. The testing data shows the accuracy of predicted data ranging from 3' to 10" for both azimuth and elevation when extrapolated satellite orbit to 7 seconds time. 2010 IEEE.
