Most GPS receiver cases have a loop on the back to hold the case on a belt. If you’re wearing shorts or tights and don’t have a belt, waist packs for carrying a radio or a cassette/CD player are an option. These packs can accommodate larger GPS receivers. They’re not very noticeable when you’re working out because they’re designed not to bounce much. Small fanny packs and waist packs that carry water bottles also carry a GPS receiver. If the GPS receiver is small, try carrying it in your front pants pocket. I’ve carried a GPS while running and cross-country skiing in trail-running shorts and tights with zipper pockets. Although satellite reception is sometimes lost while under heavy tree cover, the electronic tracker records track data as long as I have a mostly clear view of the sky. Using GPS will greatly enhance your understanding of the map-and-compass technique, but it’s wise to hone basic navigational skills before or in conjunction with use of a Personal GPS tracker . When ou...

Technology has drastically advanced and unlike the past when people needed a special satellite GPS receiver to track movements, today the GPS trackers are found in smart phones and other small gadgets. They work by connecting to the internet connection as well as receiving a signal directly from the GPS satellite, which helps pinpoint the exact location of the GPS signal. This has proven to be a truly important tool for automobile owners since the Asset GPS tracker can be installed in a secret location on a vehicle allowing security personnel to track the signal from the vehicle and locate the vehicle. Now the vehicle GPS tracking device needs to determine the time part of the formula. The answer lies in the coded signals the satellites transmit. The transmitted code is called “pseudo-random code” because it looks like a noise signal. When a satellite is generating the pseudo-random code, the personal tracking device is generating the same code and tries to match it up to the satel...

GPS technologies will help school authorities and parents to keep track of the school bus, its speed while simultaneously tracking the real time position of students. When students board or alight, their ID cards will be read by the GPS card readers installed on the school bus door. Alerts are sent to t...

The intricacies of GPS ( electronic tracking device ) are steeped in mathematics, physics, and engineering, but you don’t need to be a rocket scientist to understand how GPS works. GPS is composed of three parts: satellites, ground stations, and receivers. Eyeing satellites In GPS jargon, a satellite is the space segment. A constellation of 24 GPS satellites (21 operational and 3 spares) orbits about 12,000 miles above the Earth. The satellites zoom through the heavens at around 7,000 miles per hour. It takes about 12 hours for a satellite to completely orbit the Earth, passing over the exact same spot approximately every 24 hours. The satellites are positioned where a GPS receiver can receive signals from at least six of the satellites at any time, at any location on the Earth (if nothing obstructs the signals). A satellite has three key pieces of hardware: Computer: This onboard computer controls its flight and other functions. Atomic clock: This keeps accurate time wit...

A short history of GPS Military, government, and civilian users all over the world rely on GPS for navigation and location positioning, but radio signals have been used for navigation purposes since the 1920s. LORAN (Long Range Aid to Navigation), a position-finding system that measured the time difference of arriving radio signals, was developed during World War II. The first step to GPS came way back in 1957 when the Russians launched Sputnik, the first satellite to orbit the Earth. Sputnik used a radio transmitter to broadcast telemetry information. Scientists at the Johns Hopkins Applied Physics Lab discovered that the Doppler shift phenomenon applied to the spacecraft — and almost unwittingly struck gold. A down-to-earth, painless example of the Doppler shift principle is when you stand on a sidewalk and a police car speeds by in hot pursuit of a stolen motorcycle. The pitch of the police siren increases as the car approaches you and then drops sharply as it moves away. Americ...

What’s my favorite outdoor activity? Although I enjoy riding my mountain bike to work, what really turns me on is diving into a patch of thick woods and getting completely lost. If it’s an area I’m familiar with, all I need is a water bottle, an energy bar, and a hat in case I’m out after dark. So why would I buy a GPS tracker ? Because they’re small, they’re relatively inexpensive, and they provide the biggest tax-dollar bang-for-the-buck that I can imagine. When I switch on the GPS, I’m plugging into a multibillion-dollar satellite-based navigation system that is coddled in some manner by several of the largest and most powerful U.S. government agencies, including all branches of the military beneath the wings of the Department of Defense and the Department of Transportation. It’s almost irresistible once you realize the enormity of what a simple $150 cell phone–size device can do A GPS unit, coupled with inexpensive topographic-map software, allows you to preview your excursion, ...

Ancient travelers relied on celestial objects, such as stars, to find their way. GPS users also use celestial objects—satellites—to navigate. There are, of course, vast differences between a star and an earth-orbiting man-made object. You observe a star to navigate; a satellite is invisible to the naked eye, but you use its position data, or ephemera, to navigate. Modern navigators no longer have to wait for nightfall and clear skies, and, thanks to atomic clocks, they can receive precise position data continuously. According to the National Academy of Sciences, in 1957 scientists observing the newly launched Sputnik realized they could predict its position by measuring the increase and decrease in frequency of its radio signal as it orbited the earth. This observation confirmed that a satellite’s position in space could be accurately determined from the ground, which meant a satellite could determine the accurate position of an object on or above the ground, such as a hiker or a hang ...

GPS - the Global Positioning System - is a navigation revolution. It’s a technology that pinpoints a user’s location anywhere in the world, 24 hours a day, regardless of the weather. Designed by the United States’ Department of Defense for use by the military, the GPS System was made available to civilians for use in aviation, marine surveying and general outdoor/recreation markets. Today, millions of people utilize the accuracy and convenience of this amazing technology to hunt, fish, hike, fly, cruise and sail. GPS consists of a constellation of 24 satellites orbiting some 12,000 miles above the earth. These satellites transmit signals containing time and orbital data to calculate satellite position and almanac data. Meanwhile, receivers used on the ground, sea and air search the sky for the satellites. The GPS unit needs to acquire good signals from at least three satellites to determine a position on the surface of the earth. A fourth signal is required to get three-dimensional pos...

A tracking device can simultaneously receive signals from 4 up to 11 satellites, if the receiver is on the surface of the earth. Under this condition, there are two approaches to solve the problem. The first one is to use all the satellites to calculate the user position. The other approach is to choose only four satellites from the constellation. The usual way is to utilize all the satellites to calculate the user position, because additional measurements are used. In order to focus on this subject only the four-satellite case will be considered. If there are more than four satellite signals that can be received by a GPS receiver, a simple way is to choose only four satellites and utilize them to solve for the user position. Under this condition, the question is how to select the four satellites. Let us use a two-dimensional case to illustrate the situation, because it is 24 BASIC GPS CONCEPT easier to show graphically. In order to solve a position in a two-dimensional case, three sa...

A Global Positioning System (GPS) is a group of 24 earth-orbiting satellites, providing location and time in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS Satellites. This system of satellite can work in any weather condition, operate 24/7/365 and travel at roughly 7,000 miles an hour. A GPS receiver uses a triangular calculation to pinpoint a user’s exact location buy comparing the time a signal was transmitted with the time it was received by a satellite. The control segment of GPS ( GPS tracking device ) consists of a master control station (MCS), a worldwide network of monitor stations, and ground control stations. The MCS, located near Colorado Springs, Colorado, is the central processing facility of the control segment and is manned at all times. There are five monitor stations, located in Colorado Springs (with the MCS), Hawaii, Kwajalein, Diego Garcia, and Ascension Island. The positions (or coordinates) of these...

For ages people have been looking for ways to find locations and identify directions to different places. It all began in the first century when the Chinese used lodestone ladles whose handles always pointed towards the south no matter what direction they were placed in. In the year 1978, a Block-I GPS satellite was launched. It was basically used for defense purposes. Another milestone in the GPS system is the development of Topologically Integrated Geographic Encoding and Referencing (TIGER) a digital map that allowed users to create virtual maps. This digital map was released in 1989, and sometime before that in 1983, the US president had declared that the GPS system would be made public for everyone to use. Both these factors speeded up the process of the designing and development of GPS-enabled tracking devices in the world. Over the next few decades, more research institutions and IT-based companies began to create devices based on GPS. Now, GPS has become so commonplace that...

It’s fun to uncover something that you aren’t supposed to know about — many software applications and movies on DVD contain what are known as “easter eggs.” However, imagine finding something that you aren’t supposed to find that turns out to be useful and informative. In this article, we are going to hunt for GPS easter eggs, delving into the secrets that lie behind the standard menus on your GPS unit to find useful features and diagnostic screens that can give you information about your system and troubleshoot problems that you might have. There’s a lot of information to find — technical information, diagnostic information, and more. Let’s begin our tour of the secrets of Magnetic GPS . How GPS Works The basic principle behind GPS is straightforward: The GPS receiver picks up a signal from three or more of the satellites and then uses this information to calculate the distance to the satellites. This information is, in turn, used to determine a location on the globe where th...

A BRIEF HISTORY PRIOR TO atomic clocks, quartz-movement watches kept the most accurate time. Quartz time, based on the vibrations of a quartz crystal, is accurate to about one thousandth of a second perday. But with radio signals traveling at the speed of light, a clock that is off by even a thousandth of a second will produce a gross position error. Atomic clocks, accurate to within 1 second every 100,000 years, derive their precision from the highly predictable gains and losses of energy by atoms. These clocks, accurate to a billionth of a second, are key to the success of GPS. Ancient travelers relied on celestial objects, such as stars, to find their way. GPS users also use celestial objects—satellites—to navigate. There are, of course, vast differences between a star and an earth-orbiting man-made object. You observe a star to navigate; a satellite is invisible to the naked eye, but you use its position data, or ephemera, to navigate. Modern navigators no longer have to wait ...
