GPS Without Satellites

Current GPS systems rely on radio signals from satellites to perform their location determining calculations. When the radio signal is not available, the system cannot work. Micro-Electro-Mechanical System (MEMS) gyroscopes work like a tiny Foucault pendulum but with a vibrating element that can detect rotational changes. These small gyroscopes and accelerometors form the core of […]

1817 – gyroscope

A gyroscope is a device that can maintain a directional orientation because it is spinning rapidly and the axis of the spin resists being changed. A spinning top is a simple example. The first known gyroscope was documented by Johann Bohnenberger in 1817. In 1851 Leon Foucault demonstrated the Foucault pendulum and in 1852, coined […]
