GPS systems have become increasingly popular, portable and affordable. Sales of this navigation system off the little cards, and they are the most popular every electronics store and big box retailer around.

So, what exactly is GPS, how it works and why is it so popular? What other uses are there for the technology? For answers to these and more, keep reading.

What is GPS?

GPS stands for Global Positioning System. This technology was developed by the U.S. Department of Defense, and employs a network of 24 satellites placed strategically throughout the world. It was originally intended for military use only, but the government has made available to any person to use in the 1980s. That combined with recent advances in mobile technology has been the subject of hot new GPS. It is extremely popular with those who lead in life, such as couriers.

How does it work?

A GPS receiver uses signals from GPS satellites to triangulate the exact location. The 24 satellites circle the planet twice a day and transmit signals to the earth, which is what receivers use. The receivers use the main difference between when a signal was transmitted and received to calculate how far away the satellite.

To monitor the movement and to calculate the latitude and longitude of an object, a GPS receiver must acquire signals from at least three satellites. If you add another satellite to the mix, you can follow the altitude as well. A receiver is the location, other variables can be considered as speed, distance to destination, and more.

New advances in technology such as GPS Wide Area Augmentation System (WAAS) and Differential GPS (DGPS), it is possible to obtain an accuracy to within three meters of a signal. If WAAS is widely available in recent GPS, DGPS requires additional equipment and is mainly used in marine systems and the U.S. Coast Guard.

Popular uses for GPS

The most common application for GPS receivers is little that can be mounted in your car or carried by hand. These compact devices are typically used for directions, and speakers that give turn by turn directions spoken to avoid being distracted by looking at a small map. But GPS users are discovering new uses of technology every day.

One of the earliest uses of GPS before the handheld was the Lo-Jack. It was a chip implanted in a vehicle that police stations could be used to locate stolen vehicles. The Lo-Jack has become a source of inspiration for finding other objects, particularly those living.

GPS collars have become popular pets to roam. So when little Spot or Fluffy can not be found, you can simply use a GPS signal to find them. Missing children can be found with a popular cell phone software that uses the GPS signal to locate them.

The new handheld revolution owes much of its success to the iPod. This popular portable music player has led to the invention of hard disk technology in parallel, allowing you to double the disk space on a hard disk without increasing the physical dimensions.

So as you can see, the GPS has a lot a reasons for its success in recent years. And with a sudden and sustained increase in sales, technology has become much more popular and affordable than ever. You can buy a cheap receiver with a great brand name from about $ 150.

Each pet would require their own collar. One big downside to RoamEO is the cost. Some of its competitors are half as much as this system, at a little over four hundred dollars for a handheld unit and collar. The good thing about RoamEO is that both the handheld receiver and the collar are equipped with GPS receivers. This means that if you are on a hike, you don’t continuously have to re-create a virtual fence every step you take.

But tracking can bring challenges. By the time you reach the destination the pet will have moved on. This system only sends out updates every 3 minutes. Once your pet leaves this area, an audible alarm will sound to let you know there’s a problem. This electronic boundary is automatically stored, so it’s easy to wipe it out and replace it with a new area as you choose. They have received considerable input from cat owners asking for a product like RoamEO for their pets. As a result, they are actively investigating whether they can make a collar small enough to fit on cats. If your pet exits this perimeter, an audible alarm will sound. For example, you may wish to establish your property line as the perimeter for your pet.

The receiver picks up location information sent from the collar, including the speed of your dog, where he or she is, and how fast your pet is going. Apart from the $500 price tag (plus $160 for each additional GPS-enabled collar), the collar and receiver communicate with each other via radio, not GSM. There is no need for the collar to be off the dog for 4-6 hours while the batteries recharge, which would leave your dog unprotected during an escape without the collar. Your dog has protection 24/7/365. The signal from the collars can be detected up to 3 miles from the receiver. The RoamEO Pup’s high contrast display can be easily read in sunlight or at night.

It comes with a built-in battery that will last between 18 and 30 hours. Now each time you put on your dog’s collar, it comes with the extraordinary advantage of knowing that you can locate your pet at anytime. Just place your collar on the dog and you’re ready to track.
