Global Positioning

The NAVSTAR Global Positioning System (GPS) is a satellite-based navigation system that will provide extremely accurate three-dimensional position fixes and timing information to properly equipped users anywhere on or near the Earth. The system will be available continuously regardless of weather conditions and will find extensive utilization in improved weapons delivery accuracies, range instrumentation, &c. Furthermore it will provide an ultimate saving in the number and cost of navigation and position-fixing systems currently employed or projected. It is a Joint Service programme managed by the U.S.A.F. with deputies from the Navy, Army and Marines and the Defense Mapping Agency. The system concept evolved from U.S.A.F. and Navy studies initiated in the mid-1960s. Current programme plans call for the deployment of six satellites in 1977 to permit demonstration and evaluation tests over the continental United States. The system will then be expanded through the deployment of additional satellites into an operational 24-satellite system.

<p>Global positioning system (GPS) tracker is an innovative technology that is able to track the position of vehicle using global satellite system. In this paper, vehicle tracker system design that is derived from global positioning system and global system for mobile communication (GSM) interface with the use of Arduino Uno board as platform is proposed and presented. Technology in Arduino, GSM, and GPS is studied.GPS module receives the coordinates from the satellite. The GPS coordinates are sent to users in the form of SMS through SIM900A GSM module. By using Google Maps, the exact location of the vehicle can be located. Arduino microcontroller is the gateway to all GPS and GSM hardware and software communication in the system. The design represents that GSM and GPS interface with the use of Arduino Uno board as platform can really make vehicle tracking more efficient and convenient since it can work in any weather conditions and provide real-time location of objects. Automatic display of the coordinate’s geographical location in a map should be integrated in future design.</p>

Navigational service is one of the most essential dependency towards any transport system and at present, there are various revolutionary approaches that has contributed towards its improvement. This paper has reviewed the global positioning system (GPS) and computer vision based navigational system and found that there is a large gap between the actual demand of navigation and what currently exists. Therefore, the proposed study discusses about a novel framework of an autonomous navigation system that uses GPS as well as computer vision considering the case study of futuristic road traffic system. An analytical model is built up where the geo-referenced data from GPS is integrated with the signals captured from the visual sensors are considered to implement this concept. The simulated outcome of the study shows that proposed study offers enhanced accuracy as well as faster processing in contrast to existing approaches.
