India has unveiled new GPS-assisting tech. The new technology also tested the so-called GAGAN (GPS Aided GEO Augmented Navigation) on Thursday, Apr. 28.

The Global Positioning System models across the globe are still not perfect. It can experience various issues that will definitely affect its accuracy.
Hello Tracks provided some of the problems that GPS systems can experience during operations:
- Inaccuracy due to insufficient satellite signals.
- Cold starts after being inactive for too long.
- Poor hardware since GPS is not usually updated by airlines and other flight companies.
- GPS devices usually perform less when on low batteries.
New GPS-Assisting Tech Unveiled by India!
The United States, Russia, China, and other big nations already have some technologies to aid their GPS models. One of these is the so-called Satellite-Based Augmentation System (SBAS).

Now, India is also working on its own SBAS model, the new GANAN tech. This innovation was specifically developed by the Indian Space Research Organization (ISRO), as reported by WION.

During the recent test, ISRO used its ATR 72-600 aircraft to check if the new GAGAN system is efficient. The experiment's findings revealed that India's own SBAS system could perform well in both Tier 2 and Tier 3 airports.
Now, how can GAGAN help passenger airplanes?
How GAGAN Works
Dr. Mylswamy Annadurai, the former Director of India's UR Rao Satellite Center, explained that the new GAGAN system could correct the GPS signals.
This means that airplanes can rely on this new GPS-assisting tech to have more accurate positioning when landing and during actual flights.
He added that GAGAN's ground segment has fifteen ground stations and a Master Control Center located across India.

Recently, Japan's ASDF F-15 recently crashed and went-off radar.
Meanwhile, RAF warning was previously issued because smart meters are believed to have negative effects on the United Kingdom's EWS.
