Recently, arraying of large or small and distributed reflector antennas for uplink applications has attracted attention for a capability upgrade to the Deep Space Network (DSN). This interest is ...driven by the desire to maximize the usefulness of existing DSN large apertures in case of spacecraft emergency and to develop the necessary knowledge of how the array of small and distributed reflector antennas can meet other future uplink throughput needs. The primary challenge for uplink arraying of distributed reflector antennas for deep space applications is the lack of feedback from deep space within a reasonably short period. Furthermore, the individual reflectors (and their transmitter subsystems) are thousands of wavelengths apart, which make the phase coherence of individual transmitted signals an extremely challenging task. Because of the return light time constraints, all closed-loop calibrations and relative phase adjustments for any coherent combination of signals from individual antennas be conducted no farther than near-Earth orbits. This paper discusses the large array background, scope, and evolution, and some of the lessons learned from preliminary studies of the uplink array.
Recent advances in space technology for Earth observations, global communications, and positioning systems have created heavy traffic at a variety of orbits. These include smart sensors in low Earth ...orbits (LEO), Internet satellites in LEO and GEO orbits, Earth observing satellites in high Earth orbits (HEO), observatory class satellites at Lagrangian libration points, and those heading for deep space. In such an integrated operations environment, future ground tracking antenna networks, such as JPL/NASA's deep space network (DSN) may be required to provide highly agile beams, flexible scheduling, and the capability for simultaneous tracking of multiple spacecrafts at various orbits. In this paper the possibility of cost-effectively replacing the DSN's 26-m antennas with a network of phased array antennas capable of tracking various types of spacecrafts that are within 2 million km of Earth is examined.
