Global Positioning System (GPS) is a satellite-based navigation system that provides location and time information to receivers anywhere on Earth. The system uses a constellation of 27 satellites that orbit Earth every 12 hours. GPS was developed by the U.S. Department of Defense and was originally only accurate for military use, but has since become accurate for civilian use with applications in vehicle navigation, mapping, precision agriculture and more. GPS works by satellites transmitting coded signals that receivers use to calculate the time it takes for signals to arrive and determine distance from multiple satellites to triangulate the user's position.

GNSS - Global Navigation Satellite System
A satellite navigation system uses a network of satellites to provide geo-spatial positioning by calculating the location of a receiver on Earth from signals from multiple satellites. There are currently two global satellite navigation systems, GPS and GLONASS, as well as two more in development, Compass and Galileo. Satellite phones connect to communications satellites instead of terrestrial cell towers to provide mobile service anywhere. They have both military and civilian applications including precision weapons guidance, aircraft passenger information, and personal satellite communications.
Satellite Navigation
Satellite navigation systems use satellites to allow receivers to determine their precise location using time signals from satellites. Global Navigation Satellite Systems (GNSS) provide global coverage and include GPS, GLONASS, Galileo, BeiDou, and IRNSS. Regional systems augment global systems to improve accuracy through corrections broadcast by geostationary satellites.

Dgps concept
Differential Global Positioning System (DGPS) is an enhancement to Global Positioning System that provides improved location accuracy, from the
15-meter nominal GPS accuracy to about 10 cm in case of the best implementations. Differential Global Positioning System (DGPS) is a method of providing differential corrections to a Global Positioning System (GPS) receiver in order to improve the accuracy of the navigation solution. DGPS corrections originate from a reference station at a known location. The receivers in these reference stations can estimate errors in the GPS because, unlike the general population of GPS receivers, they have an accurate knowledge of their position.
DGPS uses a network of fixed, ground-based reference stations to broadcast the difference between the positions indicated by the GPS (satellite) systems and the known fixed positions. These stations broadcast the difference between the measured satellite pseudoranges and actual (internally computed) pseudoranges, and receiver stations may correct their pseudoranges by the same amount. The digital correction signal is typically broadcast locally over ground-based transmitters of shorter range.

GPS uses a constellation of 24 satellites orbiting Earth to provide location and time information to GPS receivers. The satellites circle the planet every 12 hours across multiple orbital planes inclined at 55 degrees to the equator, ensuring signals from 8-10 satellites are visible from any point on Earth. GPS receivers triangulate their position by measuring the time delay of signals from 3 or more satellites, determining distance based on the time required for signals to travel. Factors like ionosphere delays, multipath signals, and satellite geometry can introduce errors, but parallel channel receivers maintain locks on satellites to provide accuracy within 15 meters.

- Early experiments with computer-assisted mapping in the 1960s and 1970s led to increasingly advanced digital mapping systems through the 1980s, but the vision of a fully digital geospatial database was never achieved.
- Initiatives to establish standards and exchange of digital geospatial data internationally began in the early 1980s but concepts around ensuring quality and fitness for use were still not fully implemented over 25 years later.
- Advances in technology outpaced the capabilities of Australia's systems, with visions for applications in areas like navigation and military planning not realized even decades later due to decisions that prior
Beyond the sky
Space research : space research projects under the 7th framework programme for research (5th call)
Civilisations have always wondered what is beyond the sky. But it is only recently that the limitless possibilities provided by space science and technology came into stronger spotlight and started to be used to the full. The EU has been playing a significant role in this process, in particular through the FP7 space research programme. The 5th FP7 space call brochure – through presentation of 50 projects divided into four categories (Copernicus applications and data; space technologies; space science and data exploitation; cross-cutting issues) – aims at giving a comprehensive overview of Europe's endeavours to fully, yet sustainably, use space for purposes ranging from excellent reception of TV signal to helping victims of earthquakes and other natural disasters

GPS is a global navigation satellite system that uses 24 satellites to provide location and time information to GPS receivers worldwide. A GPS receiver calculates its position by precisely measuring the time it takes signals from at least four satellites to reach it. There are three segments to GPS - space (satellites), control (ground stations), and user (receivers). GPS provides location accuracy from around 15 meters for basic receivers to less than one centimeter for specialized survey-grade receivers.
Trimble GPS
GPS uses a constellation of 24 satellites that continuously transmit radio signals. These signals allow GPS receivers on the ground to determine their location by precisely calculating distances to 4 or more satellites. The system provides positioning anywhere in the world to within 15 meters using basic receivers, and to within 1 meter using differential GPS which accounts for errors. Surveyors can achieve centimeter accuracy using Real-Time Kinematic techniques.

- 3. Background The Global Positioning System (GPS) is a space-based Global navigation satellite system that provides location and time information. The project was started in 1973 to overcome the limitations of previous navigation systems. GPS was created by the US department of defence and was originally run with 24 satellites. It became fully operational in 1994 at the cost of twelve billion US taxpayer dollars. Freely accessible by anyone with a GPS receiver. Navigation by radio as an aid has been practiced in Germany since 1907 (Telefunken) First used as radio directional finder (RDF) between radio towers.
- 4. GPS Timeline In 1972, the US Air Force developmental flight tests of two prototype GPS receivers In 1978 the first experimental Block-I GPS satellite was launched. In 1983, civilian airliner strayed into restricted Soviet airspace due to navigational errors and shot , GPS made available for civilian use.February 14, 1989, the first modern Block-II satellite was launched. December 1993 the GPS achieved initial operational capability[51] January 17, 1994 a complete constellation of 24 satellites was in orbit. Full Operational Capability was declared by NAVSTAR in April 1995. In 1996, US declaring GPS to be a dual-use system (national asset). In 1998, two new civilian signals for enhanced user accuracy and reliability, particularly with respect to aviation safety. On May 2, 2000 "Selective Availability" was discontinued In 2004, US and European Community establishing cooperation related to Garmin GPS and Europe's planned Galileo system. November 2004, successful tests of Assisted-GPS for mobile phones.In 2005, the first modernized GPS satellite was launched and began transmitting a second civilian signal for enhanced user performance.
