The PIGA was based on an accelerometer developed by Dr. Fritz Mueller, then of the Kreiselgeraete Company, for the LEV-3 and experimental SG-66 guidance system of the Nazi era German V2 (EMW A4) ballistic missile and was known among the German rocket scientists as the MMIA "Mueller Mechanical Integrating Accelerometer". This system used ...

He developed the PIGA accelerometer. [2] and worked on gyroscopes for Nazi Germany's Kriegsmarine. Later on, he worked on the guidance and control system for the A3 test rocket, the A5, and the A4 ballistic missile. [3] Under Project Paperclip, Mueller emigrated to the United States on 16 November 1945 with the Argentina group.
From 100 mg to 10 μg for accelerometers. To get a rough idea, this means that, for a single, uncorrected accelerometer, the cheapest (at 100 mg) loses its ability to give 50-meter accuracy after around 10 seconds, while the best accelerometer (at 10 μg) loses its 50-meter accuracy after around 17 minutes.

Charles Stark "Doc" Draper (October 2, 1901 – July 25, 1987) was an American scientist and engineer, known as the "father of inertial navigation". [2] He was the founder and director of the Massachusetts Institute of Technology's Instrumentation Laboratory, which was later spun out of MIT to become the non-profit Charles Stark Draper Laboratory.

An accelerometer measures proper acceleration, which is the acceleration it experiences relative to freefall and is the acceleration felt by people and objects. [2] Put another way, at any point in spacetime the equivalence principle guarantees the existence of a local inertial frame, and an accelerometer measures the acceleration relative to that frame. [4]
An inertial navigation system is a system which continually determines the position of a vehicle from measurements made entirely within the vehicle using sensitive instruments. These instruments are accelerometers which detect and measure vehicle accelerations, and gyroscopes which act to hold the accelerometers in proper orientation.
