Global positioning system technology

Where, Inc., used Global Positioning System technology to start a family-tracking service called uLocate in 2004. Three years later, it became a location service, offering an app for mobile phones. According to its Web site, it has about 50 million users. 

As animal populations cross the international border and as they move within the various parks, they are monitored in part by means of GPS (Global Positioning System) technologies, which are important technologies in creating conservation landscapes and in their ongoing maintenance. 

More advanced applications of e-agriculture in farming exist in the use of sophisticated information and communication technologies such as satellite systems, Global Positioning Systems (GPS), and advanced computers and electronic systems to improve the quantity and quality of production (Food and Agriculture Organization of the United Nations 2005). 

In recent years, satellite positioning represented by Global Positioning System (GPS) has been in extensive application, and its accuracy and reliability are likely to improve in near future. While some train traffic control systems have already applied GPS as a means of train detection, various technological developments are also under way for the application of GPS. For example, the rotary snow blowers applied the GPS to detect where it locates in the heavy snow. However, if the snow piled up to the GPS antenna, sometimes, the detection is not possible. However, it is unclear what the relationship between the positioning performance of GPS and the depth of piled-up snow to the GPS antennas. This paper reports how dry or wet snow accretion to the GPS antenna decreases the positioning performance. 

Microwave technology is robnst. Highly stable solid state devices are commercially available that operate from 1-18 GHz. These devices can be locked to atomic clocks or global positioning systems to achieve frequency stability that far exceeds the natural linewidth of the measured rotational transitions. The result is a frequency generation system that requires little to no maintenance over long time periods (months to years), a featnre that is currently impossible to achieve with broadly tunable laser systems. These stand-alone microwave systems, which can be remotely controlled, are technically feasible and can be operated with pnsh-bntton control. ... 

Finally, the proper measurement of the effectiveness of the transportation system, in real time, offers a mechanism by which transportation managers, supply chain specialists, and industrial engineers can constantly reduce costs and improve service. With new technologies such as wireless commimication, global positioning systems (GPS), and performance-monitoring technology, measurement systems allow the users to improve transportation processes as needed. 

The emergence of global positioning systems and other spatial technologies drives the need for an LRS that can accommodate and integrate data expressed in multiple dimensions (AASHTO 2012). 

NextGen Acronym for Next Generation Air Transportation System. The latest technology in development for air traffic control, it involves satellite tracking and global positioning systems. 

Global Positioning System (GPS). GPS makes use of communications satellite technology for navigational purposes. The GPS was first developed by the government for military applications but has become widely used in civilian applications in products such as cars and mobile phones. 

I Stanford University is developing the computers and technology for a driverless car. The 2010 autonomous race car, dubbed Shelley, is an Audi TTS equipped with a differential Global Positioning System accurate to an inch. It calculates the right times to brake and accelerate while turning.
