The GPS and GIS Technologies are very powerful tools for mapping. However by integrating GIS and GPS technology the benefits are multiplied several times over.
GPS is a constellation of 27 satellites orbiting the earth at about 12,000 miles. These satellites are continuously transmitting a signal and anyone with a GPS received on earth can received this transmission at no charges. By measuring the travel time of signals transmitted from each satellite, a GPS received can calculate its distance from the satellite. Satellite position is used by receiver as precise reference points to determine the location of the GPS receiver. If a receiver can receive signals from at least 4 satellites it can determine latitude longitude, altitude and time. The satellite are in orbit such that at any time any where on the plant one should be able to receive signals from at least 4 satellites. The basic GPS services provides commercial uses with on accuracy of 100 meters, 95% of the time any where on the earth.
GPS technology offers several advantages first and foremost, the services are free word wide and any one with a receiver can receive the signals and locate a position. Second the system supports unlimited uses simultaneously third one of the great advantages of GPS in the fact that it provides navigation capability.
These services deliver Geographic Information between mobile and static users, like
the Internet and wireless network. This services enhanced safety calling, roadside assistance, personal navigation and tracking services. I mention here the area and their uses where GPS has to be used very prominently.
Fleet Management System
This system helpful for remote vehicle tracking and monitoring. It helps to manage affect of vehicle by gaining control of travel records and time. They eliminate the time consuming task of manually completing mileage logs, to track missing data or verify hand written information. These advanced system could help to manage fuel consumption, velocity, load balancing, vehicle positioning. Once data collection of the fleet activity is automated and accurate, depicting it as comprehensive report is easy, giving way to effective management and business efficacy an a highly competitive industry scenario like today.
GPS based fleet management system and their solution is dependent on the various requirements determining size, accuracy, economic constraints and the like affecting, in turn, efficiency, productivity and profitability.
GPS based feet management system could be divided in to three major types.
-
Active fleet management systems.
- Passive fleet management systems.
- Hybrid fleet management systems.
Active fleet management systems
This system is based on tracking read time data of vehicle position. These systems allow company is to contract their vehicle any time, day or night, to determine current location and immediately retrieve other vehicle usage data.
