Apollo 7 slow-scan TV, transmitted by the RCA command module TV camera. NASA decided on initial specifications for TV on the Apollo command module (CM) in 1962. [2] [ Note 1] Both analog and digital transmission techniques were studied, but the early digital systems still used more bandwidth than an analog approach: 20 MHz for the digital system, compared to 500 kHz for the analog system.

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 ...
Later, Lebar also developed a color television camera for the Apollo program, as well as the cameras for the Skylab space station. For the successful development of this camera and the color television transmissions of the Apollo program, the company Westinghouse received an Emmy in the technology category, which Lebar accepted in 1970.
English: This video shows the separation of two stages of the Saturn V launch vehicle during Apollo 4, an uncrewed test flight of the Apollo program. A camera mounted to the interior of the S-II, the Saturn V's second stage, records the separation of the S-IC, its first stage, and subsequent jettisoning of an interstage ring which connected the two stages.
A well-known gimbal lock incident happened in the Apollo 11 Moon mission. On this spacecraft, a set of gimbals was used on an inertial measurement unit (IMU). The engineers were aware of the gimbal lock problem but had declined to use a fourth gimbal. [5] Some of the reasoning behind this decision is apparent from the following quote:
The Far Ultraviolet Camera/Spectrograph was a tripod mounted, f/1.0, 75 mm electronographic Schmidt camera weighing 22 kg. It had a 20° field of view in the imaging mode, and 0.5x20° field in the spectrographic mode. [1]
The backbone of any electric gate, whether automatic or not, is the electric gate motor, two distinct motor types exist hydraulic, or electromechanical. This is the electric device which actually enables the electric gate to open and close without having to manually push the gate.
Astronaut Paul J. Weitz at the telescope's command and display (C&D) console inside Skylab during the mission (June 1973) [3]. The ATM was one of the projects that came out of the late 1960s Apollo Applications Program, which studied a wide variety of ways to use the infrastructure developed for the Apollo program in the 1970s.
