Abstract
The development of multistation tracking techniques has resulted in improved navigation (orbit determination) accuracies. Differential very long baseline interferometry (VLBI), which involves performing measurements of a spacecraft and nearby the quasar and differencing, potentially offers at least an order of magnitude improvement over data types currently implemented. A simplified model on conic motion is developed for predicting the orbit determination error given Delta-VLBI measurement error. This simplified model is applied to the large outer planets for an overall assessment of the effectiveness of Delta-VLBI orbit determination. For Venus the result is encouraging.
