This paper describes the development of the K- and Ka-band mobile-vehiclular satellite-tracking reflector antenna system for NASA's ACTS Mobile Terminal (AMT) project. ACTS is NASA's Advanced Communications Tehcnology Satellite.
We are conducting a search for supernovae in starburst galaxies at the IRTF. Teh najor difficulty is to reliably detect weak point sources in the presence of a bright and structured background.
Because of questions regarding the validity of proposed accreted terranes, the tectonostratigraphic evolution of the southern margin of North America plate in Mexico remains controversial.
This paper discusses a series of aeronautical experiments that utilize the Advanced Communication Technology Satellite (ACTS) Broadhand Aeronautical Termninal (BAT)[1]. These experiments were designed to explore the uses ...
The Jet Propulsion Laboratory (JPL) has recently begun the development of a Broadband Aeronauical Terminal (BAT) for duplex video satellite communications on commercial or business class aircraft. The BAT is designed for ...
Simultaneous dual-frequency Ka-band (32 GHz) and X-band (8.4 GHz) carrier signal data have been acquired during the superior conjunction of the Cassini spacecraft June 2001, using the NASA Deep Space Network's facilities ...
A superior solar conjunction occurs when the sun lies near the signal path of a source as observed from the Earth. Interplanetary spacecraft sent to the planets typically encounter one or more solar conjunctions during ...
(View graphs) NASA's Deep space missions have used 960 MHz, 2.3 GHz, and 8.4 GHz for spacecraft communications dowlinks. Ka-band (32 GHz) is being considered as a downlink frequency for future flight projects.
