Global Positioning System (GPS)

GPS is a navigational system offering information under any weather condition from any area that falls within its range, from anywhere in and near the earth.  This project was developed in the year 1973 to break the restrictions and challenges the previous systems faced. It was initially run with the help of twenty-four satellites and became completely operational in the year 1994. The system has been modernized and developed since then.
GPS’s design is primarily based on land-based navigation systems like Decca Navigator and LORAN, developed during the Second World War period. In 1960, the first successful navigator, named Transit, was experimented on by the United Nations’ navy. It was able to provide a navigation fix of roughly once an hour and was comprised of five satellites.
The Timation satellite in 1967 was the first to implement clocks in space. After tweaking and learning from its predecessors, the Omega Navigation System became the first official global radio navigation system, during the next decade.

The Global Positioning System is owned by the Government of the United States and stewarded by the Department of Defense. Successful mobile GPS tests were done in 2004 and a modernized satellite navigation system was launched in the year 2005. It has become a handy tool for people around the world.

NAVSOP

A new system have been developed to protect military vehicles from GPS jamming by using already existing radio waves to locate rather than relying on GPS satellite signals. The system uses cell phone, Wi-Fi, and TV signals to locate a person or a vehicle but can even use GPS jamming signals to correctly get a position fix.

Known as NAVSOP, this technology scavenges radio signals from the air and can work indoors or even underground where wimpy GPS satellite signals can’t reach. This technology could replace GPS in the future.

Garmin Fenix

Garmin came out with a new GPS watch called Garmin Fenix.
Some of the highlights of Garmin Fenix, in addition to the GPS receiver of course, is the compass, altimeter, barometer, and the optional external ANT connected temperature sensor. Some other features include the ability to plan trips and create routes, record waypoints, and record GPS bread crumb trails. You can also navigate to coordinates if you wish. You also get a 3-axis electronic compass to get your heading even when you’re stationary.

Fenix, which is water proof to 50 meters can last 50 hours in GPS mode and up to 6 weeks in plain watch mode.
