Cellphones can double as navigators

MINI EXIM POLICY 2004- IMPACT

The government yesterday removed all import restrictions on Global Positioning System (GPS) equipment.

Until now operators required a number of permission, including clearance from the defence ministry, to set up a GPS network.

D K Ghosh, executive director, Siemens Public Communications said: "The move is a step in the right direction as it will boost GPS usage in the country, which is extremely rich in applications."

Today's announcement will benefit cellular and satellite operators, logistics companies and technology providers.

The code division multiple access (CDMA) based WLL operators in the country will also benefit since there is an in-built element of GPS in the CDMA technology.

For consumers, this means enhanced new applications. In the US, for instance, GPS is used to provide mapped directions to users while driving.

Rajan Mehta, vice-president of Nortel Networks said: "Mobile operators are looking to increase their revenue streams. The removal of restrictions would enable them to offer location based services. GPS would also help in engineering, construction and planning in sectors which require mapping and involve understanding the topography of an area."

Technically speaking, GPS is a network of 66 satellites which allow to pin point the location of an object or person with high-precision.

Any single point is covered by a combination of three satellites which give the exact longitude and latitude.

Applications for GPS include many. It could range from simple mobile applications like locating the nearest movie theatre or it could involve complex usage like mapping of an area. Defence forces, for instance, use the technology for locating enemy positions.

The technology is also used by logistics companies to keep track of goods and vehicles on road. The Indian railways is also planning to use the technology for securing the rail tracks.
