The current assets of the deep space network (DSN) of the National Aeronautics and Space Administration (NASA), especially the 70-m antennas, are aging and becoming less reliable. Furthermore, they are expensive to operate and difficult to upgrade for operation at Ka-band (321 GHz is shorthand for the allocated 31.8-32.3 GHz. GHz). Replacing them with comparable monolithic large antennas would be expensive. On the other hand, implementation of similar high-sensitivity assets can be achieved… Expand

The Effect on Spacecraft Tracking Performance of Using an Array Instead of a Single Dish for Receiving
TLDR
An examination of each item of single-dish tracking error budgets shows that for typical tracking applications arraying has very little effect on the phase of the array signal when compared with the signal from a single dish having the same A/T, and thereforearraying has negligible effect on tracking performance as compared with a single Dish.
