GPS application prospects eleven blocks of detail description

GPS application prospect is broad, not only involves the military, now it is popularized to all aspects of people's lives. Now there are eleven pieces of GPS application prospects are described in detail as follows:

I. Timing

In addition to longitude, latitude, and elevation, the Global Positioning System (GPS) provides a critical fourth dimension - time. Each GPS satellite is equipped with multiple atomic clocks that provide very precise time data for the GPS signals, and GPS receivers can decode these signals, effectively synchronizing each receiver with those atomic clocks. This allows the user to determine time with trillionths of a second accuracy without having to own an atomic clock.

II. Roads and Highways

The use and accuracy of the Global Positioning System (GPS) can increase the safety and efficiency of vehicles on highways and streets, as well as public transportation systems. Many of the problems of assigning and dispatching commercial vehicles have been significantly reduced thanks to GPS. Similarly, problems faced by public transportation systems, road maintenance and emergency vehicles have been greatly reduced.

As GPS continues to be modernized, we can expect more effective systems to prevent crashes, warn of distress, notify location, provide electronic maps, and in-vehicle navigation devices with voice instructions.

III. Space

The Global Positioning System (GPS) has revolutionized and modernized the way many nations operate in space, from navigational systems for manned spacecraft to managing, tracking, and controlling a constellation of communications satellites to monitoring the Earth from space. The benefits of using GPS include:

Solving navigation problems-providing highly accurate orbit determination with existing GPS equipment that meets space-use levels and a minimal ground crew.

Solving altitude problems - replacing high-cost on-board altitude sensors with low-cost multiple GPS antennas and specialized algorithmic programs.

Solving timing problems - replacing expensive spacecraft atomic clocks with low-cost GPS receivers with precise timing.

Satellite swarm control - Provide a single point of contact for orbital maintenance control of a large number of spacecraft such as a constellation of communications satellites.

Formation Flying - Achieve precise satellite formations with minimal ground personnel intervention.

Virtual Platform - Provides automated “station keeping” and relative position services for advanced scientific tracking operations such as interferometry.

Launch spacecraft tracking - replacing or augmenting tracking radars with high-precision, low-cost GPS devices for range safety and automated flight termination.

IV. Aviation

Pilots around the world utilize GPS to improve flight safety and efficiency. Because of its accuracy, continuity and global performance, GPS provides seamless satellite navigation services that fulfill many of the requirements of aviation users. Space-based positioning and navigation can determine a three-dimensional position during all phases of flight, from take-off, flight and landing, to ground navigation at airports.

The trend towards utilizing the concept of area navigation suggests that GPS is taking on an even more important role. Area navigation allows an aircraft to fly from one point to another on a user-selected route, and these fixes do not need to be referenced by ground infrastructure. A number of programs have been extended to utilize GPS and its augmentation services in all phases of flight. This is especially true when there is no appropriate ground-based navigational aid or monitoring equipment in the flight area.

V. Agriculture

The combination of the Global Positioning System (GPS) and Geographic Information Systems (GIS) has enabled the development and application of precision agriculture and the practice of site-specific farming. These technologies enable real-time data collection and precise positioning information to be combined into one, so that large amounts of geospatial data can be effectively manipulated and analyzed. In precision farming, GPS can be used for cultivation planning, mapping of cropland, soil sampling, tractor navigation, crop monitoring, variability applications, and harvest mapping, etc. GPS allows farmers to work in poor visibility conditions such as rain, dust, fog, and darkness.

VI. Maritime Transportation

The Global Positioning System (GPS) has changed the way the world works. This is especially true for maritime operations, including search and rescue, where GPS provides the fastest and most accurate method of navigation, speed measurement, and positioning for mariners. It has increased the level of safety and efficiency for mariners around the world.

Railroads

Railroad systems in many parts of the world use the Global Positioning System (GPS) in conjunction with a variety of sensors, computers, and communication systems to improve safety, security, and operational efficiency. These technologies help to reduce accidents, delays and operating costs. An essential prerequisite for the efficient operation of a railroad system is the availability of accurate, real-time location information about locomotives, cars, maintenance vehicles, and wayside facilities.

Environment

Balancing human needs while preserving the Earth's environment requires better decisions based on up-to-date information. Collecting accurate and timely information is a great challenge for government and private organizations that need to make such decisions. Global Positioning System (GPS)
