Mapping can be done with GPS and laser rangefinder directly in the field ( for example by Field-Map technology ).

Advances in technology and new demands on the existing system have now led to efforts to modernize the GPS system and implement the next generation of GPS III satellites and Next Generation Operational Control System ( OCX ).

In 1967, the U. S. Navy developed the Timation satellite that proved the ability to place accurate clocks in space, a technology required by GPS.

Decades later during the early years of GPS, civilian surveying became one of the first fields to make use of the new technology, because they could reap benefits of signals from the less-than-complete GPS constellation years before it was declared operational.

Using Global Positioning System ( GPS ) technology as a reference, these antennas automatically re-aim to the satellite no matter where or how the vehicle ( on which the antenna is mounted ) is situated.

Some modern designs even go as far as using GPS technology or heart-rate monitoring capabilities.

Example of modern equipment for surveying ( Field-Map technology ): GPS, laser rangefinder and field computer allows surveying as well as cartography ( creation of map in real-time ) and field data collection.

Modern surveys generally use magnetometers with GPS technology to automatically record the magnetic field and their location.

More recent technology such as GPS and cellular networks have permitted courts to order more specific restrictions, such as permitting a registered child sex offender to leave his home at any time of day, but alerting authorities if they come within 100 metres of a school, park, or playground.

Dead reckoning is today implemented in some high-end automotive navigation systems in order to overcome the limitations of GPS / GNSS technology alone.

It is usually used to reduce the need for sensing technology, such as ultrasonic sensors, GPS, or placement of some linear and rotary encoders, in an autonomous robot, thus greatly reducing cost and complexity at the expense of performance and repeatability.

Although GPS ( Global Positioning System ) technology is reliable, offshore yachtsmen use celestial navigation as either a primary navigational tool or as a backup.

One technology used to allow GPS receivers to continue to operate in the presence of some confusing signals is Receiver Autonomous Integrity Monitoring ( RAIM ).

Other examples of wireless technology include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones.

In fact bar-headed geese have never been directly tracked ( using GPS or satellite logging technology ) flying higher than, and it is now believed that they do take the high passes through the mountains.

With the use of modern GPS technology, it can now be proved that the Salar de Uyuni is not perfectly flat.

His fortune resulted from selling an iPhone application called the " iToilet ", which utilizes GPS technology to direct the user to " acceptable " public restrooms closest to them, wherever they are.

The SPOT Messenger is manufactured by Globalstar partner Axonn LLC and combines the company's simplex data technology with a Nemerix GPS chipset.

The use of hand held GPS technology and aerial and satellite images for reconnaissance during exploration became common.

Currently, technology allows a driver to issue voice commands on both a portable GPS like a TomTom and a car manufacturer navigation system.

It was at this meeting that " the real synthesis that became GPS was created.

As miniaturized electronics became cheaper, watches have been developed containing calculators, tonometers, barometers, altimeters, a compass using both hands to show the N / S direction, video games, digital cameras, keydrives, GPS receivers and cellular phones.

The formal name then became WGS 84 ( G730 ), since the upgrade date coincided with the start of GPS Week 730.

It was the most widely used long-range navigation system until the advent of GPS ( which was developed from it and only became available to the public in 2000 ) and LORAN is being enhanced and retained as a land-based alternative to the satellite-based system.

This is a Snowdonia hill that became a mountain in September 2008 when it was measured by three Welshmen with GPS equipment and found to be 30 inches taller than previously thought, thereby exceeding the height required to classify as a mountain by six inches.

The development of GPS by the United States in the 1980s allowed for precise navigation and positioning and soon became a standard tool in surveying.

During 2005, DeLorme became the first company to sell a USB GPS device, the Earthmate GPS LT-20, for less than $ 100.

Established in 1986 as New Zealand-based Talon Technology, Navman ( as the company became known in the 1990s ) is a GPS systems company providing stand-alone GPS units, OEM GPS modules, GPS software for Palm handhelds and Pocket PCs, automotive navigation systems and navigation systems for use at sea.

In 1973 he became manager of the NAVSTAR GPS development program, where he remained until 1978 when he retired from the Air Force.

After five years outside of academia, however, Parkinson returned to his alma mater Stanford, where he became research professor focused on GPS and related technologies.

The Global Positioning System ( GPS ) is a space-based satellite navigation system that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites.

With the individual satellites being associated with the name Navstar ( as with the predecessors Transit and Timation ), a more fully encompassing name was used to identify the constellation of Navstar satellites, Navstar-GPS, which was later shortened simply to GPS.

The traditional spirit level produces these practically most useful heights above sea level directly ; the more economical use of GPS instruments for height determination requires precise knowledge of the figure of the geoid, as GPS only gives heights above the GRS80 reference ellipsoid.

The modernization programme also contains standardized features that allow GPS III and Galileo systems to inter-operate, allowing receivers to be developed to utilise GPS and Galileo together to create an even more precise GNSS system.

To do this, a local clock is corrected to the GPS atomic clock time by solving for three dimensions and time based on four or more satellite signals.

* Many more computers and other technologies were implemented in vehicles throughout the decade such as: Xenon HID headlights, GPS, DVD players, self-diagnosing systems, memory systems for car settings, back-up sensors and cameras, in-car media systems, MP3 player compatibility, USB drive compatibility, keyless start and entry, satellite radio, voice-activation, cellphone connectivity, HUD ( Head-Up-Display ) and infrared cameras.

Despite the increased cost in hardware, this type of embedded system is increasing in popularity, especially on the more powerful embedded devices such as Wireless Routers and GPS Navigation Systems.

It is more reliable, and often more accurate, than a GPS receiver for measuring altitude ; GPS altimeters may be unavailable, for example, when one is deep in a canyon, or may give wildly inaccurate altitudes when all available satellites are near the horizon.

Global Positioning System ( GPS ) receivers can also determine altitude by trilateration with four or more satellites.

* GPS route, a series of one or more GPS waypoints

This method only provides the position in two coordinates and is more difficult to use than GPS.

At 0000 GMT September 30, 1996 ( the start of GPS Week 873 ), WGS 84 was redefined again and was more closely aligned with International Earth Rotation Service ( IERS ) Terrestrial Reference Frame ( ITRF ) 94.

At the same time, the use of more precise physical measurement techniques, including differential GPS, remotely sensed digital terrain models and laser scanning techniques, have allowed quantification and study of these processes as they happen.

For plot level fusion, time tagging using a standard GPS clock ( or similar ) is more than sufficient.

Presently GPS TEC is monitored and distributed in real time from more than 360 stations maintained by numerous agencies in many countries.

The GPS system uses many more satellites than were used with TRANSIT, allowing the system to be used continuously, while TRANSIT provided a fix only every hour or more.
