Sparton Releases Inertial Navigation System with Integrated SAASM GPS

De Leon Springs, Fla. — (BUSINESS WIRE) — Oct. 9, 2017 — Sparton Corporation (NYSE:SPA) announced the release of the INS-20. The INS-20 is the first of its kind – a MEMS-based Inertial Navigation System (INS) that integrates SAASM GPS with the industry leading heading accuracy of the Sparton AHRS-M2.

The INS-20 provides fully compliant Selective Availability Anti-Spoofing Module (SAASM) GPS security with an onboard SAASM receiver. The system integrates SAASM GPS input with sensor input from the AHRS-M2 to provide a robust INS capable of operation in GPS deprived or denied environments. The INS-20 is also capable of integrating multiple serial inputs from external sensors, allowing them to operate as part of a unified navigation system.

The INS-20 is a compact, low power INS that provides full self-location and navigation capability including latitude, longitude, altitude, heading, pitch, roll, and velocity. Ideal for SWaP-C requirements, the INS-20 is compact and weighs only 31 grams with low power consumption of 1W.

“The INS-20 really is one of a kind,” said Jim Lackemacher, Group Vice President of the Engineered Components and Products Segment. “No other inertial navigation system in its class provides the feature set of the INS-20 in such a compact and versatile package.”

Benefits of INS-20:

  • Integrated SAASM GPS and Sparton AHRS-M2
  • Operates in GPS denied/degraded environments
  • Easily integrates additional external sensors and inputs for a unified navigation system operation
  • Compact size and weight and low power ideal for SWaP-C applications
  • Ideal for Assured Positioning, Navigation, and Timing (A-PNT) and hand-held or mounted optical targeting systems

Features of INS-20:

  • Selective Availability Anti-Spoofing Module (SAASM)
  • SAASM GPS coupled to Sparton AHRS-M2 through AdaptNav™ filter algorithm
  • Sparton AdaptCal™ 3D adaptive in-field calibration with hard and soft magnetic interference compensation
  • Improved GPS tracking with position data output rate of 100 Hz
  • Static Heading Accuracy of 0.02° RMS
  • Extended performance in a jamming environment – 41 dB while tracking – 24 dB in acquisition
  • Small form factor of only 31 g for combined system
  • Full 360° rollover capability using quaternions or rotation matrix
  • “Figure of Merit” real time heading error indicator
  • Quality of in-field calibration indicator
