GPS or Global Positioning System is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial users around the world. It is freely accessible to anyone with a GPS receiver.

Advances in technology and new demands on the existing system have now led to efforts to modernize the GPS system and implement the next generation of GPS III satellites and Next Generation Operational Control System (OCX). In addition to GPS, other systems are in use or under development.

This technology will be introduced in Iloilo City by Satellite GPS Tracking and Asset Management System Corporation. Its device, called SafeSat, will launch tomorrow at Hotel del Rio.
