The consideration of short-arc and long-arc tracking error budgets can begin with a look at the overall error problem. A typical error breakdown for the GEOS-C altimeter is indicated in Table I. Quantities associated with factors other than the orbit errors have an rms value of approximately 3 meters. This leaves 4 meters or so which can be assigned to the calibration process if the 5 meter rms overall accuracy goal is to be met. Allowing 1 or 2 meters for uncertainties associated with the geoid means that the uncertainties associated with the orbit determination process should contribute no more than about 3.5 meters.
