MEMS inertial sensors are devices that detect and measure tilt, shock, rotation, vibration or any other types of motion. These sensors are mainly of three types, namely accelerometers, gyroscopes and magnetometers. Global MEMS Inertial Sensor Market to grow at a CAGR of 14 percent over the period 2014-2019.
When the GPS is inaccessible, whether as a result of a malfunction (or obvious indifference), or as a consequence of enemy action, information critical for navigation must be gathered using the missile’s on-board sensors. DARPA’s Chip-Scale Combinatorial Atomic Navigator (C-SCAN) effort seeks an atomic inertial sensor to measure orientation in GPS-denied environments.
