According to the source the system is designed to provide accurate position information to users in India and as far as 1,500 kilometers (932 miles) from its borders and a less accurate extended service area would cover the region enclosed by latitude 30º south to 50º north, longitude 30º east to 130º east. The satellites will be able to track the location and position of vehicles, provide information during natural disasters and integrated with mobile phones for navigation and other location services.
