Abstract
Navigation capabilities of noncoherent tracking data are evaluated for interplanetary cruise phase and planetary (Venus) flyby orbit determination. Results of a formal covarjance analysis are presented which show that a combination of one-way doppler and ADOR yields orbit accuracies comparable to conventional two-way doppler tracking. For the interplanetary cruise phase, a tracking cycle consisting of a 3-hour doppler pass and ADOR (differential one-way range) from.two baselines (one observation per overlap) acquired 3 times a month results in 100-km orbit determination accuracy. For reconstruction of a Venus flyby orbit, 10 days tracking at encounter consisting of continuous oneway doppler and ADOR sampled at one observation per overlap is sufficient to satisfy the accuracy requirements.
