Global Positioning Satellite Technology

By: Muna wa Wanjiru

The technology of today has given us an ingenious device with which we can find our way through unfamiliar places. This device is simply called a gps system or to be more exact global positioning satellite. This interesting device was originally devised by the military to navigate their aircraft and other systems with the aid of tracking satellites.

The original global positioning satellite system was designed sometime during the late 1960s. This device was called Transit and it utilized seven satellites and radio signals to receive and send coordinate information. The next improvement to the global positioning satellite system was developed during that same time period. Unlike its predecessor this new gps system worked using an atomic clock.

Even though these were all improvements on the navigational process there were still issues of inefficiency and inaccuracy to be dealt with. To combat this problem the Navy and the Air Force joined forces and created a new gps device. This device was called Navigation System and Ranging or the shorted form was called NAVSTAR. The launch of this device came about during the early 1970s.

Once the system was perfected to a large degree, the point of use swung towards the general public as well. Today you will see many different uses for the global positioning satellite systems. These range from cell phone, car gps systems, hiking gps devices, hand held devices. There is even a patent pending for a global positioning satellite system to be embedded into shoes that children wear.

These are just a few of the many different applications you will find global positioning satellite systems being used for. While many of the uses of these devices are helpful, there are issues about privacy which need to be settled before too long. At the moment the benefits of using these gps devices outweighs the disadvantages. This is especially true of cell phone uses who have become stranded or been in an accident.

In the earlier time periods there was no actual way of determining the location of cell phone callers who needed help. This was due to the fact that their phones themselves were not traceable, unlike that of land phones. This problem has been resolved with the embedding of global positioning satellite technology.

Today all new cell phones have this technology embedded into their systems. As a result emergency and rescue services now have an easier time locating and providing help to cell phone users.

With so many new ways of finding people and places it seems hard to imagine that a small device can take us places. Today the city streets are open to us thanks to global positioning satellite technology, tomorrow who knows where we will venture.
