Gps And Its Application

GPS and its Application Countries using GPS worldwide

Environment 

Natural canals are being detected and accurately mapped using GPS in a project affecting Argentina, Bolivia, and Paraguay. To facilitate flow for the Pilcomayo River, which is heavy in sediment deposits, the precise height of new channels is designed to keep sediment moving.

Boosting the gold mining industries 

In 1998,GPS technology helped the Australian Geological Survey Organization conduct a 14-week airborne survey of Western Australians Eastern Goldfields region. The survey was aimed at improving understanding of the regions geology, with a particular focus on the areas where thin, weathered material cover potential gold-bearing rocks. Information that came out of the survey will help the gold mining industry determine what activities it will conduct in the region, and will assist the national and local governments create resource development strategies. The survey aircraft used GPS navigation equipment to map ground positions with an accuracy better than five meters. This type of surveying has also been done to map potential goldbearing areas in Queensland.

Seeking mineral deposits  An exploration company in Australia is using GPS to search for mineral deposits in the remote areas of Western Australia. Detection of certain mineral deposit suggests the presence of valuable ore bodies.

Direct Traffic Control is a state of the art personal computer based train control system used to electronically manage and validate train movements in non-signaled territory.  With DTC, computers in the locomotives and at the control centre exchange codes by radio which are used to verify the authorization of train movements. Train movement advice is then displayed on the respective computer screens.  DTC uses GPS to provide warnings to the driver that the end of an authority is near or if an authority has been exceeded. DTC also uses GPS to calculate and display the locomotives current location at all times.

Digital maps of Bangladesh are proving invaluable in the fight against sleaze in a country branded as one of the most corrupt in the world. The maps are used together with a computerized national database to decide where new roads or schools should be built. The aim is to ensure that tough decisions about development priorities and spending are governed by local needs rather than the whim of politicians.  "It has become an excellent planning tool to plan and identify priorities, said Quamrul Islam Siddique, who pioneered the scheme. "This information is open, transparent and available to all." 

Natural Disasters  

Reducing damage due to flooding  GPS data has been used in Bangladesh to find ways to mitigate the flooding damage during the monsoon season. Due to its low-lying geography and the effect of siltation, Bangladesh is extremely susceptible to flooding of its inland waterways. Using hydrographic survey systems that incorporated GPS measurements, researchers recently collected data before and after the monsoon season at various sites in an effort to create mathematical models of riverbeds and volumes of water discharged in the waterways. The models will be used in developing plans to alleviate damage caused by flooding.

Maritime & Waterways 

The Bangladeshi government has undertaken a plan to install a satellite-delivered differentiate global positioning system (DGPS) that it will use to determine exact position of marine vessels, off-shore objects and aircraft. The 220 million taka (about $4.44 million in U.S. dollars) project, financed by the World Bank, will be implemented by the Bangladesh Inland Water Transport

Telecommunications  

Facilitating the expansion of telecommunications  Telecommunications companies in Australia are currently taking advantage of GPS to provide information on positioning in order to manage the telecommunications infrastructure throughout New South Wales. Dual frequency GPS receivers, which can attain centimeter accuracy, are proving very useful in allowing surveyors to precisely position sensitive telecommunications infrastructure, such as microwave and satellite communication antennas, mobile phone transmitter stations, and radio masts. GPS is also being used to survey around potential sites for telecommunications assets in order to enable infrastructure designers to optimize the heights of transmitter masts and the positions of guy lines to support the masts.

Infrastructure Development 

Electrifying rural regions :



Eskom, South Africans national electric utility, has been using GPS along with geographic information system (GIS) technology to bring electricity to rural areas in South Africa, where there are often no street addresses to guide the electric company. Before using GPS, electric company field workers had to attempt to map the coordinates of a home on a map by hand, an often imprecise technique. Today, field workers involved in the rural electrification project tote a GPS/GIS receiver and data logger with them to rural sites to tag the home with a precise GPS position and to record information about the type of electric system the building will use. This enables the installation crew and any repair crews to easily locate the house and have knowledge of its electric system when needed.

Archeology & Educational Research 

Reconstructing an ancient fortress : Surveyors from the Geodetic Institute of the Technical University Munich recently employed surveying software that processes GPS data in a project to map the remains of an ancient Roman settlement in Syria. Called Al Hallul, this former city's fortified walls and buildings have been eroding due to exposure to the elements as well as Bedouins use of its stones to build new homes. Although many walls were incomplete, surveyors were able to use the GPSdependent software to plot data on the remnants of the city's walls and buildings. In the end, the surveyors were able to make a completely reconstructed map of the original city and in much shorter a time than it would have taken to manually plot all of the detail points they surveyed.

Forestry & Agriculture 

Repopulating Thai forests  Thailand has implemented a reforestation program using GPS equipment. A New Zealandbased forestry consulting firm worked with the Thai government on this project, which has provided Acacia Magnum trees to Thai farmers. Growing well in infertile tropical soil, this type of tree is an optimal source of wood fiber for the paper and pulp processing industries.

Maritime & Waterways 

 

All Rio de la Plata pilots use GPS to guide their vessels through the very narrow and shallow channels. We have also tested the system in the Uruguay and Parana Rivers. Mapping underwater obstacles during hydrographic surveys  In Argentina, 400 GPS units were installed in fishing boats operating in national waters to monitor commercial fishing activities and protect Argentina's fisheries resources, which account for 4.5 of the country's exports. Using the monitoring system can verify a fishery's compliance with regulations and automate catch reports. Commercial fishing operations can file reports electronically, providing authorities with almost instantaneous information on fish stocks. Over-fished areas can be closed and commercial fishing operations can otherwise be aided to maximize their catch. This system is already in use on more than 700 commercial fishing boats in Argentina, Australia, United Kingdom, United States, and New Zealand.

Infrastructure Development

Lighting up Indonesia 

 The government of Indonesia recently used GPS technology to evaluate the possibility of using solar and wind energy systems to provide electricity to remote villages of Indonesia. Officials wish to use such systems to ensure that electricity will be environmentally sustainable. Surveyors visited villages on several islands to create precise maps detailing power infrastructure locations in reference to the villages. They used geographic information system equipment to quickly gather very accurate measurements and also to collect and store information about the potential electrical load of each household surveyed. The Indonesian government was able to use the collected data to compare villages electricity needs and establish a priority list for electrifying communities.

Improving taxi service and safety  

Australian taxi cabs are using GPS tracking systems to increase productivity as well as to protect drivers. Having the ability to track cabs with system, dispatchers can ensure that their companies drivers reach passengers quickly and thus do more business per day. In addition, cabs GPS receivers are linked to an emergency response system. When the driver pushes a button in the case of an attack, the unit sends message to dispatchers, who can contact police with the exact location of the incident. The GPS system can also allow dispatchers to track stolen cabs and relay the information to the police.

Flood management  

A major benefit from the development of GPS is to prevent ecological disaster. Protecting the environment remains an important function of GPS around the world. Notably on a project impacting Argentina, Paraguay and Bolivia, natural canals are detected and accurately mapped using GPS, and precise height of new channels are designed to facilitate flow for the Pilcomayo River, which fills with sediment. This will keep sediment moving through Patino Estuary using river canals to restore the Pilcomayo's flow. Companies in Argentina use the GPS's precise-positioning technology to help police find stolen and hijacked vehicles.

Charting a course through mountains 

Canada's North Shore Search and Rescue Team has used GPS to identify trail locations and features in the North Shore Mountains of Vancouver, British Columbia. Aerial photography and other traditional survey methods are not easy to use in making sense of trails. Participants in the North Shore mapping project used GPS to accurately map and assess the features of the trails nestled in the North Shore Mountains in order to create a map of the trail networks that would help the rescue crew in their operations. They also planned to develop a map from the data that can help hikers avoid becoming lost in the trail networks

Aiding the work of an avalanche rescue crew 

  Iceland's avalanche rescue squad, Karaborg Hvammstanga, now uses GPS in its work. While communicating by VHF radio, the mountain rescue team can take advantage of the GPS equipment to ensure their and others safety during avalanche rescues and severe weather conditions. The GPS equipment the rescuers use is waterproof, can calculate speed and velocity allowing for ground conditions, and can accept differential corrections.
