PIGA accelerometer: History & Art

A PIGA (Pendulous Integrating Gyroscopic Accelerometer) is a type of accelerometer that can measure acceleration and simultaneously integrates this acceleration against time to produce a speed measure as well. The PIGA's main use is in Inertial Navigation Systems (INS) for guidance of aircraft and most particularly for ballistic missile guidance. It is…
