GPS in Navigation

The Department of Electronics funded project of Bangalore Metropolitan Transport Cor[poration fopr development of GPS receivers for hand held and air borne applications. The main applications of the projectis control of private operators by obtaining information on route traveled by the bus and timing. The target is to generate billing information based on route kms traveled. The route kms data will be validated by the vehicle monitoring system at the control center for violations in route and time. The system generates several reports and statements based on queries such as buses plying in a given route at a given time of the day, etc.

A GPS receiver continuously acquires position data using the GPS satellites. The GPs receiver is mounted on the target vehicle. The latitude and longitude of the vehicle, transmitted by the GPS module is written into local memory or transmitted to a Central Control Sysetm. Off-line monitoring system process the stored information in the memory of the GPS receiver to derive the required vehicle monitoring information. On-line systems require transmission of the GPS data from the vehicle to the Central Control Station. VHF/UHF wireless networks are used for the transmission of GPS data to the Control Centres.

Bharat Electronics (BEL) developed hand-held and air-borne receivers and offers to users for trials and feedback was received. BEL is developing new model incorporating the user recommendations and other facilities available in contemporary equipments. On the basis of GPS technology, BEL developed other GPS-based products like (1) Integrated Fish Finder and Navigation Guidance Systems (IFFNGS), (2) vessel identification system (VIS). Vehicle Tracking And Monitoring Systems (VTMS), (4) GPS Intregration with VHF, HF Radios and SATCOM Terminals.

IFFNGS aids the fishermen in reaching the probable fishing zones (PFX) accurately and avoids blind netting. Already 100 nos. are sold to Department of Ocean Development (DOD) and about 50-60 are installed in the fishing vessels. VIS system monitors the vessels on the sea at the shore station any point of time It aids in rescuing operation in ase of emergencies and helpd in avoiding smuggling and poaching activities. This costeffdective vessel monitoring system can be used to track the airborne platforms. GPS integrated with VHF and HF radiosare being offered to Army, Navy and Airforce. I t aids the soldier in navigating without the help of a map and atomaticreporting of the position of the troop to control station.
