Tracking with the Proposed Array-based Deep Space Network

D.S. Bagri

Abstract:	This paper describes a possible approach to make range, doppler and angular position (tracking) measurements for a spacecraft with the proposed array-based deep space network (DSN). Considering how each item from the single dish range, doppler and angular position error budgets is affected by arraying, we expect that tracking performance for the array-based system should be similar to that achieved using single large antennas. An array-based system allows for the possibility of using same beam interferometry, which potentially can provide very high accuracy relative spacecraft angular position information. We will discuss considerations for a proposed array-based DSN that would enable same beam interferometry routinely.
