Effect of Linear Approximation for Satellite Doppler Frequency in Geodetic Positioning.
Abstract
The Doppler principle has been used to track satellites since the early 1060's. When the data sampling interval was less than one second, this data has been treated as frequency data in orbit determination programs. This method results in an approximation when the number of cycles counted in an interval divided by the time interval is treated as a frequency in the equations of condition. The result of this truncated series is that it produces station heights that are about 1.4 meters too low. Therefore the data must be treated as range differences, even for sampling intervals as low as 1 second. (Author)
