The whole system weighed 43 kg and required 103 W of power. The electronics was located inside the Apollo Service Module. The two halves of the dipole antenna were retractable, on the two sides of the service module itself, while the Yagi used for VHF was stowed close to the main engine and then deployed into position after launch.
This was distinct from the unified S-band high-gain antenna used for communication with Earth at lunar distances. The earlier Block I design of the Apollo spacecraft carried the scimitar antennas inside two semicircular strakes attached near the base of the Command Module, which were intended to improve aerodynamic stability during reentry ...
Another critical step in the evolution of the Apollo Network came in 1965 with the advent of the DSN Wing concept. Originally, the participation of DSN 26-m antennas during an Apollo Mission was to be limited to a backup role. This was one reason why the MSFN 26-m sites were collocated with the DSN sites at Goldstone, Madrid, and Canberra.
It claims to be the only remaining example in the world. The larger 29.8-metre (98 ft) parabolic dish antenna was commissioned in late 1969. The OTC Satellite Earth Station Carnarvon, an Earth station in Australia, was established to meet the need for more reliable and higher quality communications for the Apollo program.
Apollo 15 Lunar Module and Lunar Roving Vehicle, August 1, 1971.The S-band dish antenna for the rover is visible. The Unified S-band (USB) system is a tracking and communication system developed for the Apollo program by NASA and the Jet Propulsion Laboratory (JPL).
After the cancellation of the Apollo Project the station supported Skylab until its re-entry in 1979 when the station joined the Deep Space Network in support of the Viking and Voyager projects. 1981 saw the closure of the station and its 26 m antenna was moved to CDSCC to become known as Deep Space Station 46. After the antenna was removed the ...
Apollo Command Module primary guidance system components Apollo Lunar Module primary guidance system components Apollo Inertial Measurement Unit. The Apollo primary guidance, navigation, and control system (PGNCS, pronounced pings) was a self-contained inertial guidance system that allowed Apollo spacecraft to carry out their missions when communications with Earth were interrupted, either as ...
The station is one of three [5] satellite communication stations in the NASA Space Communications and Navigation (SCaN) program’s Deep Space Network (DSN), whose mission is to provide the vital two-way communications link that tracks and controls interplanetary spacecraft and receives the images and scientific information they collect.
