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.

Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
A scimitar antenna is a radio antenna so named because its shape resembles a talon-shaped curved sword of the same name. It was invented in 1958 by Edwin M. and William P. Turner. It is essentially a flat metal plate in a semi-circular or semi-elliptical shape with a wide end at one side and a narrow point at the other.
The Apollo Lunar Surface Experiments Package (ALSEP) comprised a set of scientific instruments placed by the astronauts at the landing site of each of the five Apollo missions to land on the Moon following Apollo 11 (Apollos 12, 14, 15, 16, and 17). Apollo 11 left a smaller package called the Early Apollo Scientific Experiments Package, or EASEP.
Astronauts manually flew Project Gemini with control sticks, but computers flew most of Project Apollo except briefly during lunar landings. [6] Each Moon flight carried two AGCs, one each in the command module and the Apollo Lunar Module, with the exception of Apollo 7 which was an Earth orbit mission and Apollo 8 which did not need a lunar module for its lunar orbit mission.

It supplied life support systems for two astronauts for up to four to five days on the Apollo 15, 16 and 17 missions. The spacecraft was designed and manufactured by the Grumman Aircraft Company. The descent stage contained the landing gear, landing radar antenna, descent propulsion system, and fuel to land on the Moon
