Recently the television carried two apparently unrelated news from different parts of the globe. The first was a report on a swimming competition in the Sarangani Bay in Philippines held in May last month. The other was an announcement for an expedition by South American scientists supported by WWF through the Amazon and Orinoco Rivers to survey freshwater dolphins. Interestingly, one noticed both these events had a common underpinning – GPS was the key enabler in both events. The swimmers in Philippines swam across guided by course marker boats fitted with GPS receivers to get the exact position of the shortest line from start to finish. In the Amazon expedition each time a scientist would see a dolphin their position will be noted using GPS.

GNSS applications have grown over the years and are constantly touching new horizons. As one imagines all possible application areas, every day one discovers yet another realm within the GNSS world!

It is just like an anecdote about a teacher who pulled out a large jar and filled it with stones. When the jar was full leaving no room for any other stone to be fitted in he asked his students whether the jar was full to which all students affirmed that it was. He then reached under the table and pulled out a bucket of gravel and poured it into the jar as the gravel flowed into the spaces between the stones. He once again asked the students if the jar was full. This time the students figured out that probably the jar was not full yet. Now the expert brought out a bucket of sand and poured it as the sand filled up all the space between the stones and gravel.

In the same manner one would truly have to stretch one’s imagination to fathom the scope, which the jar of GNSS applications may embrace!
