Apollo-era Saturn V Instrument Unit Telemetry Assembly, measuring 10.5″ x 6.5″ x 11″, with the front bearing a NASA George C. Marshall Space Flight Center parts tag that reads: “Telemetry Assembly, Assy No. 50Z13000-035, Mod. No. B1, Contr. No. NAS8-14000, Accept Date. 11/68, Serial No. 430, Wt. (LB) 18.82, Mfd. By TTL / BECO.” The front features a group of four ports and the latched upper lid can open to reveal the internal parts, including numerous Subcarrier Oscillators and a single output Mixer Amplifier. In fine condition, with scattered scuffs and marks.
The Saturn V Instrument Unit (IU) was a crucial component of the Saturn V rocket, which was used by NASA during the Apollo program to send astronauts to the Moon. The IU was located at the top of the third stage (S-IVB) of the Saturn V rocket and served as the "brain" of the vehicle, controlling its guidance, navigation, and control systems.
The Telemetry Assembly within the Instrument Unit was responsible for collecting and transmitting various data points from the rocket's systems back to mission control on Earth. This telemetry data included information about the rocket's orientation, velocity, altitude, engine performance, fuel levels, and other critical parameters. This data was essential for mission controllers to monitor the health and status of the vehicle during its ascent and journey into space.
