                            Basic GPS signals:
The original GPS design contains two ranging codes: the Coarse/Acquisition (C/A) code, which is freely available to the public, and the restricted Precision (P) code, usually reserved for military applications.
	Coarse/Acquisition code:
	The C/A code is a 1,023 bit deterministic sequence called pseudorandom noise (also pseudorandom binary sequence) (PN or PRN code) which, when transmitted at 1.023 megabits per second (Mbit/s), repeats every millisecond. These sequences only match up, or strongly correlate, when they are exactly aligned.
	Each satellite transmits a unique PRN code, which does not correlate well with any other satellite's PRN code. In other words, the PRN codes are highly orthogonal to one another. This is a form of code division multiple access (CDMA), which allows the receiver to recognize multiple satellites on the same frequency.
	Precision code:

	It Can be Used to Track Things and People
	One great function of a GPS system is that it can be used to track anything irrespective of it being static or flexible, it can also be used to track people and animals depending on what you need it for. Another great feature of a GPS system that makes it better is the alarm system it has; for example, you can easily install a GPS tracking system in a vault where valuable goods are so that you can be alarmed anytime someone is trying to steal them.
	You can also use the GPS technology to ensure things are going fine with people working for you especially if they’re doing a job that requires a high level of security and confidentiality; this will be able to track them anywhere they go and when they go there.
	It Can be Used Anywhere in the World
	An added advantage of the GPS system is that it can be used anywhere in the world; it doesn’t matter whether you’re in Africa or Asia the GPS technology is powered by the world satellites and this means it can be accessible anywhere; all you need is a solid tracking system and a GPS receiver.
	GPS technology has matured into a resource that goes far beyond its original design goals. These days people from a plethora of professions are using GPS in ways that make their work more productive, safer, and sometimes even easier. There are five main uses of GPS today:
	Location- determining a basic position.
	Navigation- getting from one location to another.
	Tracking- monitoring the movement of people and things.
	Mapping- creating maps.
	Timing- providing precise timing.
	The first and most obvious application of any Location Based Service such as GPS is the simple determination of a “position” or location. GPS was the first positioning system to offer highly precise location data for any point on the planet, in any weather. Knowing the precise location of something, or someone, is especially critical when the consequences of inaccurate data are measured in human terms.
	GPS helps you determine exactly where you are, but sometimes it is more necessary to know how to get somewhere else. Recall that GPS was originally designed to provide navigation information for ships and planes. So it’s no surprise that while this technology is appropriate for navigating on water, it’s also very useful in the air and on the land.

A GPS tracking unit is a device that uses the Global Positioning System to determine

the precise location of a vehicle, person, or other asset to which it is attached and to

record the position of the asset at regular intervals. The recorded location data can be

stored within the tracking unit, or it may be transmitted to a central location data base,

or internet-connected computer, using a cellular (GPRS), radio, or satellite modem

embedded in the unit. This allows the asset's location to be displayed against a map

backdrop either in real-time or when analysing the track later, using customized


A GPS tracking system uses the GNSS (Global Navigation Satellite System) network.

This network incorporates a range of satellites that use microwave signals which are

transmitted to GPS devices to give information on location, vehicle speed, time and

direction. So, a GPS tracking system can potentially give both real-time and historic

navigation data on any kind of journey.

A GPS tracking system can work in various ways. From a commercial perspective,

GPS devices are generally used to record the position of vehicles as they make their

journeys. Some systems will store the data within the GPS tracking system itself

(known as passive tracking) and some send the information to a centralized database or

system via a modem within the GPS system unit on a regular basis (known as active


 A PASSIVE GPS TRACKING SYSTEM will monitor location and

will store its data on journeys based on certain types of events. So, for

example, this kind of GPS system may log data such as turning the ignition on

or off or opening and closing doors. The data stored on this kind of GPS

tracking system is usually stored in internal memory or on a memory card

which can then be downloaded to a computer at a later date for analysis. In

some cases the data can be sent automatically for wireless download at

predetermined points/times or can be requested at specific points during the


 AN ACTIVE GPS TRACKING SYSTEM is also known as a real-time

system as this method automatically sends the information on the GPS system

to a central computer or system in real-time as it happens. This kind of system

is usually a better option for commercial purposes such as fleet tracking and

individual vehicle tracking as it allows the company to know exactly where

their vehicles are, whether they are on time and whether they are where they

are supposed to be during a journey. This is also a useful way of monitoring

the behavior of employees as they carry out their work and of streamlining

internal processes and procedures for delivery fleets.

(1.2) WHAT IS GPS?

The Global Positioning System (GPS) is actually a constellation of 27 Earth-orbiting

satellites (24 in operation and three extras in case one fails). The U.S. military

developed and implemented this satellite network as a military navigation system, but

soon opened it up to everybody else.

Each of these 3,000- to 4,000-pound solar-powered satellites circles the globe at about

12,000 miles (19,300 km), making two complete rotations every day. The orbits are

arranged so that at any time, anywhere on Earth, there are at least four satellites

"visible" in the sky.

prevention, we can only expect the use of GPS tracking systems to increase in

the next few decades.

 As technology continues to evolve, GPS tracking devices will continue to

decrease in size, increase in accuracy, and be utilized by even more businesses

as a common, yet powerful tool.

Business Opportunities :

 As more businesses demand the conveniences and fiscal benefits offered by

GPS tracking systems, the demand for distributors of GPS tracking equipment

and service providers will certainly increase.

 GPS tracking systems represent an already profitable business opportunity that

will only expand as demand continues to rise.

•Advancements in Software :

 Already highly-sophisticated, GPS tracking software plays a key role in how

businesses use GPS tracking systems to meet their needs.

 As satellite mapping and computer imagery continue to advance, so will the

capabilities and applications for GPS tracking software.

• Personal Safety :

 Unfortunately, it seems that violent crimes and abduction are going to be a

horrible reality for this and future generations.

 Personal GPS tracking systems are already being used to enhance the safety of

many children and adults, and as GPS tracking systems continue to become

more affordable, it's likely that they'll be used even more for this purpose.
