Gravity Deformation Measurements of NASA’s Deep Space Network 70-Meter Reflector Antennas
نویسندگان
چکیده
All of NASA’s Deep Space Network (DSN) 70-m reflectors were measured using a Leica TDM-5000 theodolite. The main-reflector surface was measured at five elevation angles so that a gravity deformation model could be derived that described the main-reflector distortions over the entire range of elevation angles. The article describes the measurement equipment and accuracy and the results derived from the data.

An Array Feed Radial Basis Function Tracking System for NASA's Deep Space Network Antennas
The use of radial basis function networks for fine pointing NASA’s 70-meter deep space network antennas is described and evaluated. We demonstrate that such a network, working in conjunction with the array feed compensation system, and trained using the computationally efficient orthogonal least-squares algorithm, can point a 70meter deep space antenna with rms errors of less than 0.3 millidegr...
متن کاملRadio Frequency Optics Design of the 12-Meter Antenna for the Array-Based Deep Space Network
Development of very large arrays of small antennas has been proposed as a way to increase the downlink capability of the NASA Deep Space Network (DSN) by two or three orders of magnitude, thereby enabling greatly increased science data from currently configured missions or enabling new mission concepts. The current concept is for an array of 400 × 12-meter antennas at each of three longitudes. ...

The Deep Space Network (DSN) [1] was established in 1958 and since then it has evolved into the largest and most sensitive scientific telecommunications and radio navigation network in the world. The purpose of the DSN is to support unpiloted interplanetary spacecraft missions and support radio and radar astronomy observations in the exploration of the solar system and the universe. There are t...
متن کاملThree-Antenna Doppler-Delay Imaging of the Crater Tycho for Uplink Array Calibration Applications
Uplink arrays have the potential to greatly increase NASA’s deep-space command and communications capabilities and to provide greater reach during spacecraft emergencies. However, due to long round-trip light times, it is not practical to phase up and track the carrier phase of each antenna element using real-time measurements at the spacecraft. This article describes a method for utilizing the...
متن کاملKa-Band Monopulse Antenna-Pointing Systems Analysis and Simulation
NASA’s Deep Space Network (DSN) has been using both 70-m and 34-m reflector antennas to communicate with spacecraft at S-band (2.3 GHz) and X-band (8.45 GHz). To improve the quality of telecommunication and to meet future mission requirements, JPL has been developing 34-m Ka-band (32-GHz) beamwaveguide antennas. Presently, antenna pointing operates in either the open-loop mode with blind pointi...
