Global Navigation Satellite Systems Engineering, Policy, and Design
The European Union Aviation Safety Agency (EASA) has released a revised Safety Information Bulletin (SIB) addressing the growing issue of Global Navigation Satellite System (GNSS) outages and disruptions. This updated advisory, SIB No. 2022-02R3, highlights the increasing sophistication and impact of GNSS jamming and spoofing, which have become significant concerns for aviation safety.

Finnair, the sole international airline operating flights to Tartu, Estonia, has announced a temporary suspension of its daily service to the city from April 29 to May 31. This decision is in response to ongoing GNSS interference issues that have recently caused disruptions, including two instances last week where flights had to return to Helsinki.

CMC Electronics and the Autonomy & Positioning division of Hexagon, which includes the Hexagon | NovAtel brand, have unveiled an innovative advancement in GNSS positioning technology. This partnership has resulted in the creation of a multi-constellation, multi-frequency (MCMF) GNSS platform, aiming to set new benchmarks in aviation navigation and safety.

Scientists at Draper Laboratory have patented a celestial navigation system called a sliced-lens star tracker, which in its early form can achieve 50-meter accuracy in GNSS-denied environments. Improvements are expected as the technology evolves. Vehicles of all kinds may be able to benefit when using this system for navigating by the stars.

Rapidly changing motion means that every aspect of positioning must be carefully re-examined and re-evaluated to avoid costly and dangerous positioning errors. The frequent changes in heading, acceleration and deceleration inherent in rockets, missiles, jet planes, race cars and other platforms — up to 100 times per second! — dictate a very high rate of data inputs from both inertial and GNSS sensors to capture the complex trajectory.
