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 ST-124-M3 inertial platform was a device for measuring acceleration and attitude of the Saturn V launch vehicle. It was carried by the Saturn V Instrument Unit , a 3-foot-high (0.91 m), 22-foot-diameter (6.7 m) section of the Saturn V that fit between the third stage (S-IVB) and the Apollo spacecraft.
Diagram of Saturn V instrument unit. The Saturn V instrument unit is a ring-shaped structure fitted to the top of the Saturn V rocket's third stage and the Saturn IB's second stage (also an S-IVB). It was immediately below the SLA (Spacecraft/Lunar Module Adapter) panels that contained the Apollo Lunar Module. The instrument unit contains the ...
An astronomical instrument is a device for observing, measuring or recording astronomical data. They are used in the scientific field of astronomy , a natural science that studies celestial objects and the phenomena that occur in the cosmos, with the object of explaining their origin and evolution over time.
A pair of scales: An instrument for measuring mass in a force field by balancing forces. Balance; Check weigher measures precise weight of items in a conveyor line, rejecting underweight or overweight objects. Inertial balance; Katharometer; Mass spectrometers measure the mass-to-charge ratio, not the mass, of ionised particles. Weighing scale
In 1973, the year after the Apollo lunar program ended, three Apollo CSM/Saturn IBs ferried crews to the Skylab space station. In 1975, one last Apollo/Saturn IB launched the Apollo portion of the joint US-USSR Apollo–Soyuz Test Project (ASTP). A backup Apollo CSM/Saturn IB was assembled and made ready for a Skylab rescue mission, but never ...

The Apollo 14 Passive Seismic Experiment (PSE) was placed on the lunar surface on February 5, 1971, as part of the Apollo 14 ALSEP package. The PSE was designed to detect vibrations and tilting of the lunar surface and measure changes in gravity at the instrument location.
