Passive fleet management systems
Passive system is not having real time transmission of data. An on board memory with in each vehicle logs the GPS tracking information and upload it to an office based P con the vehicles return to base.
The passive system is designed more for companies that need to manage their fleets by reviewing the usage of the vehicle but does not need this information in real time. Fleet managers often want to track information such as when and where delivery vehicles stop and for what duration or generate speeding reports.
Passive systems are very cost effective. The passive system hardware is typically laps expensive than the system hardware and in addition, there are no ongoing airtime costs for SMS bother of a wireless network
Hybrid Fleet Management
These combine both active and passive system for companies that want the advanced management information available from passive solution plus the ability to locate vehicle instantly.
These system are definitely more cost effective than AVI system because have these is the choice of polling location data when the data is uploaded, on return in the base station.
Marine Navigation
GPS is useful to safe navigation of ship at sea and in connected waters. The electronic navigation chart and GPS position of ship, where input to a computer system called on electronic chart display and information system or ECDIS provides a real time graphic display of ships position on a video screen along and with respect to the Geo Graphical Information contained in the ENC.
GPS methodology are used for survey for geodetic control ashore, point positioning methods and bone line methods fishing charts, coastal zone management.
Air Craft Navigation
The GPS is the only navigation system, which has the capability to show the user his exact position on the earth anytime, in any weather, anywhere. Due to its versatility economy and reliability and the rapid advancement in the aircraft are now equipped with GPS navigation systems. As a follow up, all the international airport in the world are now required to be surveyed with reference to the world Geodatic reference system. The systems is being used for numerous applications, including surveying, geodesy, geodynamics, vehicle guidance systems, navigation in land vehicles, aircraft and
The GPS control work is used in Nagpur airport is probably the first of its kind for airport survey.
Data Collection
GPS is useful for field data collection and verification, data viewing, what lies during disaster relief, rehabilitation and resource operations. Due to limitations of communications backbone transition between server and client must be bare minimum.
-
Real time data collection for dynamic application related to disaster
- Mapping of Infrastructure facilities like school, post office, health center, bank, maternity dispensary, bus stop, police station, electric power etc.
- Visualization of village and population affection based on flood condition
- Visualization of relief and rehabilitation center and route for approach
- Position of drinking water sources and its services zone
- Handing tool for health worker, who has to move door to door for data collection
- Mapping of forest boundary, area affected by forest fire, area under energy plantation
- Provide information in tabular form regarding agencies and individual with their resources and responsibilities for the purpose of the disaster management
- Road network mapping within village and connectivity to relief center
- User friendly forms for social economic data collection for GIS databases
