Boreas D90

The Boreas D90 is a strategic-grade GNSS-INS that combines Advanced Navigation’s new ground-breaking DFOG (Digital Fiber Optic Gyroscope) technology with a dual antenna RTK GNSS receiver to deliver position, velocity and orientation data with superior accuracy and reliability. With ultra-fast gyrocompassing capabilities, the system can determine heading to 0.01 degrees secant latitude without the need for magnetic heading or GPS.

Housed in an IP67-rated precision aluminium enclosure, the unit has been designed and tested to MIL-spec standards and is ideal for the most demanding offshore and marine survey applications.
