It seems that one of the top three GPS runners watch at the moment is the latest Timex Speed-Distance. The watch seems to be used widely by athletes as it provides them with precise measurements during workouts. This particular GPS watch offers benefits such as speed measurement and distance as well as altitude measurement. It has an auto pause feature along with a lap and target speed, and even pace alarms. The Indiglo night-light uniformly lights the surface of the watch dial .There is also target distance alerts and navigation. . GPS transceiver calculates speed and distance data and transmits to watch with synchronized Digital FM Signal for display

The Timex has a speed measurement, which displays your speed in various formats, such as kph, etc. The auto lap is a programmed log of each lap you travel during running time and you can use this feature to work on your speed. Auto pause is a good facet because if read this entry »

Anyone who has used a great GPS system, including a great motorcycle GPS system, will know how user friendly and useful a good GPS can be. With modern GPS technology coming of age and modern digital mapping technology improving, a great motorcycle GPS can turn a ride into a pleasure.

What is GPS? For those who don’t know, GPS stands for Global Positioning System. It is a navigation and positioning technology pioneered by the US army, that has been taken to it’s ultimate and turned into a complete user friendly modern navigation solution. Whilst in the past GPS was really just the province of the military, the technology is now so good, and so cheap, that anyone needing the ultimate in navigation can afford it.

That includes motorcyclists, modern motorcycle GPS has also come of age.

Basically GPS works by cross referencing the signals from a number of satellites above the head of the user and using those references to plot the user’s position on the globe. It will only work where there are available satellites, so if you can’t pick up the signals your GPS won’t work.

Modern GPS is accurate, depending on the number of satellites available, to wit read this entry »

GPS Navigation Systems have come a long way

Gps systems have come a long way since they were first designed for the US millitary. The first signal from NAVSTAR 1 was received on Feb. 22, 1978. NAVSTAR 1 was launched from Vandenberg Air Force Base in California and was the first of 24 satellites that make up the Global Positioning System (GPS). The first generation of satellites that make up the Global Positioning Systems 24 satellites were launched between Feb. 22, 1978 and Oct. 9, 1985. Since it First became operational the Global Positioning Systems has revolutionized the way America read this entry »

Global Positioning System

The Global Positioning System (GPS) is the only fully functional Global Navigation Satellite System (GNSS). Utilizing a constellation of at least 24 medium Earth orbit satellites that transmit precise microwave signals, the system enables a GPS receiver to determine its location, speed/direction, and time.

Developed by the United States Department of Defense, it is officially named NAVSTAR GPS (Contrary to popular belief, NAVSTAR is not an acronym, but simply a name given by Mr. John Walsh, a key decision maker when it came to the budget for the GPS program[1]). The satellite constellation is managed by the United States Air Force 50th Space Wing. The cost of maintaining the system is approximately US$750 million per year,[2] including the replacement of aging satellites, and research and development. Despite these costs, GPS is free for civilian use as a pub read this entry »
