GM-200A - Galaxy Navigation Corp
Galaxy Navigation Corp.
Tactical grade GM-200A® GNSS/IMU
GM-200A® is a high performance silicon based 10-degree-of-freedom sensors which
integrated with next generation GNSS receiver and has UART digital output. This
high reliability inertial measurement system provides high precision 3-axis angular
rate and linear acceleration. Inertial package intended for navigation, control,
dynamics testing and instrumentation applications.
GM-200A® achieves its excellent performance by employing proprietary algorithms
to characterize and correct for the effects of temperature, linearity and misalignment.
