5 Quick Facts About GNSS/INS Systems

Passenger PlaneGNSS is an acronym for “Global Navigation Satellite System.” This is a generic term used to describe satellite navigation systems that provide worldwide coverage. GNSS is the umbrella term for other navigational systems around the world, including Global Positioning System or GPS, the European GNSS Galileo, and the Chinese GNSS BeiDou.

On the other hand, INS is an acronym for “Inertial Navigation System.” This particular system makes use of acceleration and rotation information derived from an IMU or Inertial Measurement Unit. Professionals, then use the information gathered to compute position and velocity.

What does GNSS/INS mean?

This term describes the fusion of the two powerful systems to come up with a single unit that enhances each other’s capabilities. With the GNSS and INS systems combined, the resulting system has the ability to provide a more powerful and efficient navigational solution. The GNSS, for instance, can only provide accurate time and location to the navigation system if the conditions are good. Otherwise, the INS takes over until the GNSS conditions are back to normal.

What exactly does a GNSS/INS system do?

Pilots, professional drivers, and even travelers and regular commuters use GNSS/INS systems provided by companies such as CAST Navigation every day, especially when traveling via air or land. Professionals also use these signals in telecommunications, as well as Earth observation studies, especially in the prediction of possible natural disasters. GNSS signals also help in upholding civil security.

How are GNSS/INS systems tested?

When the GNSS was fairly new, experts had two options for navigation system testing: either a simulation in a laboratory or an actual field test. At present, experts prefer to test navigation systems in a controlled environment, mainly because lab tests are highly repetitive. Lab tests also allow experts to gauge performances based on real events and theories.
