Aerobraking Trajectory Options for the First Mars Micro-Mission Telecom Orbiter
A small, interplanetary spacecraft is being developed for launch as a piggyback payload on the Ariane V.
Galileo Telecom Link and its Application to Future Missions
On May 23, 1996, Galileo successfully switched to a new telecommunication mode with upgraded software on the spacecraft and comprehensively revised ground equipment. The new link offers multiple techniques (arraying, error-correcting coding, data compression, etc) to maximize the data return, while applying automation to minimize the complexity and cost of operations.
Galileo's Telecom Using the Low-gain Spacecraft Antenna
Galileo's accomplishment of a science-rich mission through a low-gain antenna was made possible by a coordinated efforts of the Deep Space Network Support team, the spacecraft designers, and the science principal investigators.
MSL Telecom Automated Anomaly Detection
Deformation in the form of natural hazards like earthquakes, volcanic eruptions and landslides, to ecosystem disturbances, to changes in the cryosphere (measurements of polar ice caps, ice sheets and sea ice).
Large Phased Array Radar Using Networked Small Parabolic Reflectors
Multifunction phased array systems with radar, telecom, and imaging applications have already been established for flat plate phased arrays of dipoles, or waveguides. In this paper the design trades and candidate options for combining the radar and telecom functions of the Deep Space Network (DSN) into a single large transmit array of small parabolic reflectors will be discussed. In particular the effect of combing the radar and telecom functions on the sizes of individual antenna apertures and the corresponding spacing between the antenna elements of the array will be analyzed. A heterogeneous architecture for the DSN large transmit array is proposed to meet the radar and telecom requirements while considering the budget, scheduling, and strategic planning constrains.
