Inertial Navigation System

PR # 0011951392

GENERAL: Aberdeen Test Center (ATC) is requesting the procurement of seven (7) inertial navigation systems that use MEMS inertial sensors, such as accelerometers and rate sensors, in addition to Global Navigation Satellite System (GNSS) receivers and one (1) GNNS base station to measure the performance of vehicle systems in highly dynamic environments. Each system outputs linear velocity, linear acceleration, angular rates, and position in an integrated package.

Each system shall be supplied with all cables, antennas, and configuration software.
