Abstract
A preliminary analysis of the information content inherent in differenced doppler and differenced range data [Quasi-VLBI (very long baseline interferometry)] is made to illustrate why these data types may be superior to conventional data types, when the spacecraft is at a low declination or is subject to unmodelable accelerations. This simple analysis, based upon a 3 parameter model of the range and range-rate observables, shows that in certain circumstances the differenced data types can be expected to improve the accuracy of the orbit determination solution. Some hardware and calibration requirements which will insure that the data will be of sufficient quality are briefly discussed.
