Reliable GPS-Denied Navigation

Highly Accurate

SkyPASS is north-finding in challenging conditions, with less than 2-mil heading accuracy and 4-mil pitch/roll accuracies. It provides absolute positioning so you can make important navigation decisions without GPS.

Works in Difficult Conditions

Because it’s driftless, spoof-proof, and not affected by magnetic disturbances, you can count on SkyPASS in difficult situations. 24/7 operation ensures that it’s always working to bring you home safely, even in civil twilight or at night.

Quick and Easy to Use

Every second counts when you’re on the move. That’s why SkyPASS has an immediate time-to-fix, and there’s no setup or leveling required. It’s easy to install and integrate into your system or platform.

Low Swap-C

Small and Energy-Efficient

When it comes to mission-critical equipment, efficiency matters. SkyPASS is small enough to hold in your hand and requires low power to operate, making it easy to fit in existing systems and platforms.

Cost-Effective

With SkyPASS, you can navigate with confidence without breaking the bank. This system offers high-quality performance at a fraction of the cost of other GPS-denied navigation options.

Customizable

SkyPASS can be used on almost any platform including UAS, vehicle, personnel, far-target locator, watercraft, and aircraft. It can be customized to fit your mission or platform as needed.

Inspired by Nature, Powered by Polarization

For thousands of years, humans have used celestial navigation to explore the seas and discover new territories, including the ancient Polynesians who skillfully navigated among the islands of the South Pacific* and the Vikings who used sky polarization to guide their ships.

Sky Polarization provides powerful navigation information that is used by many insects and birds to help them find their way.

SkyPASS which stands for Sky Position and Azimuth Sensing System, combines nature-inspired navigation techniques with cutting-edge technology to help you reach your destination safely. Utilizing sky polarization increases the availability of the system in twilight and in cloudy skies.

How SkyPASS Works

SkyPASS uses sky polarization, sun/moon, and star tracking to get an accurate heading and determine your position when GPS is lost, even in challenging conditions such as civil twilight or at night.
