Access the full SPARROW Gen II data sheet and see how autonomous navigation performs in GPS-denied environments.

Sparrow combines a passive optical system, embedded computer, and AutoNav software to navigate purely from images of the night sky. Rather than relying on radio signals from satellite systems like GPS, Sparrow images stars, celestial bodies, and satellites to determine navigational state.

GPS-denied environments are areas where GPS signals are unavailable, degraded, jammed, or spoofed (faked). Since Sparrow does not use radio signals whatsoever, it is completely unaffected by these environments.

Sparrow is inherently resistant to jamming and spoofing because it uses a passive optical system and onboard computing rather than relying on externally transmitted signals. This eliminates the ability to interfere with or manipulate navigation inputs - such as GPS signals - by external actors. 

The traditional global navigation satellite system (GNSS) is made up of signals that can be disrupted or manipulated. Sparrow operates independently of GNSS using onboard optics and processing, making it significantly more resilient in contested or denied environments.

Sparrow has demonstrated 50-meter accuracy on low-speed/stationary platforms and 250-meter accuracy on high-speed aerial platforms. Accuracy increases as more images are collected, and RSA continues to use improvements to hardware and software to increase accuracy.

Yes, Sparrow is designed as a bolt-on hardware solution that integrates into existing vehicle systems without requiring a full redesign.

Sparrow is built for use across air, land, and sea platforms, supporting a wide range of operational environments.

Sparrow enables autonomous navigation by providing reliable navigation independent of GPS, allowing vehicles to operate without reliance on external signals.
