AVIATION

Aviation

Modern aviation relies heavily on precise and reliable navigation systems, especially in environments where GPS signals may be unavailable or degraded. Two important inertial sensing technologies used in aircraft navigation are Fiber Optic Gyroscopes (FOG) and Micro-Electro-Mechanical Systems (MEMS). Both are core components of Inertial Navigation Systems (INS) and Attitude and Heading Reference Systems (AHRS).

In aviation, FOG systems are preferred for high-accuracy, long-duration navigation, while MEMS systems are valued for cost-effectiveness and compactness. Increasingly, hybrid systems combine MEMS sensors with GPS and advanced filtering algorithms to enhance performance. Together, FOG and MEMS technologies play a vital role in ensuring safe, reliable, and precise aircraft navigation in modern aerospace operations.

BUSINESS JET:

EMCORE quartz MEMS solid-state SDG-1000 series and SDG-500 inertial gyroscopes provide vital sensory data for attitude & heading reference systems (AHRS), short term navigation, and flight controls with excellent bias stability, repeatability, and vibration performance for extremely accurate sensing. Their inherent design and “one-piece” (no moving parts) create high reliability and long-life characteristics. Compact and versatile, these units can operate on a stand-alone basis, providing necessary data to drive a breadth of instruments.

HELICOPTERS:

The EMCORE quartz MEMS QRS-116 gyroscope can quickly identify and enable instantaneous control adjustments for gyro systems in pitch and roll angles, serving as independent devices for sophisticated flight control. Our SDI-500 Tactical IMU (Inertial Measurement Unit) and TAC-450 FOG IMUs raise the bar of sophistication in self-contained devices capable of unprecedented random angle walk values without loss of tactical grade levels across military environments. The SDN-500 INS/GPS Tactical System INS provide navigation, guidance, and control with the same capabilities that assure retention of tactical grade levels, delivering a complete system solution ideally suited for integration into existing systems. Our devices are packaged in a highly miniaturized, ultra-small footprint volumes.
