Silicon Sensing, Psionic partner to advance GNSS-denied navigation

Silicon Sensing gyro to support GNSS-denied navigation from Psionic SurePath system

Silicon Sensing Systems has been contracted by Psionic Inc. to supply the CRH03 tactical-grade gyroscope to equip its SurePath navigation system.

SurePath is a completely self-contained navigation solution developed to solve the growing issue, across many platform types, of effective navigation over extended periods in GNSS-denied or contested environments. SurePath’s navigational capability is based on proprietary doppler laser technology, developed initially by NASA, to support autonomous lunar navigation and landing. Able to capture real-time 3D velocity to precisely determine location, SurePath’s unique, mission-critical operational capabilities render it RF invisible and undetectable – it cannot be jammed, spoofed, or defeated.

The Silicon Sensing CRH03 gyro will serve as an ultra-precise heading sensor, providing constant azimuth data to the SurePath solution filter and bringing critical improvements to heading calculations over time. 

“Precise azimuth control and sensor data are crucial for accurate navigation and overall system functionality in GNSS-denied and contested situations,” said Sean McCormack, senior vice president at Psionic. “SurePath will integrate the data from the CRH03 into our proprietary filtering techniques to deliver enhanced capability to our end user.”

The CRH03 is a tactical-grade, stand-alone, micro electro-mechanical system (MEMS) gyroscope that delivers exceptional bias instability, angle random walk and low noise performance. Available in five rate ranges:  ±10°/s, ±25°/s, ±100°/s, ±200°/s, ±400°/s, this all-silicon unit has comparable bias characteristic to far larger and less rugged fibre-optic (FOG) and dynamically-tuned gyroscopes (DTG).
