The Indian satellite based augmentation system (SBAS),

Has widely been used in aviation since its inception.

However, the applications in non-aviation segments

Such as railways, surveys, marine, disaster management, LBS, research …

Have been not only been encouraged but also publicised time to time

Like Real Time Train Information System, Gagan Message Service (GAMES) and many more.

As in this issue of Coordinates, Mr Narayan Dhital provides

An assessment of GAGAN performances for precision aircraft approach and landing (page number 9),

Would n’t it be prudent to evaluate if the potential of GAGAN applications in other segments has been optimized?
