Before long GPS will become almost as common as the telephone, or more likely included with every mobile phone.  GPS can calculate locations accurate to a matter of.  In fact, incredibly with advanced forms of GPS you can achieve measurements to less than a centimeter!

In a sense it’s like giving every square meter on the globe a unique address.  GPS receivers have become extremely economical as they have been miniaturized to just a few integrated circuits.  These days GPS is finding its way into cars, boats, planes, construction equipment, movie making gear, farm machinery, laptop computers and especially  mobile phones.

Tracking cell phones is a active topic with a lot of interest.   A lot of the discussion surrounding cell tracking, cell phone GPS and cell phone tracking software programs could be helped by a GPS Satellite introduction and glossary.

GPS is an acronym for Global Positioning System.   GPS satellites broadcast signals from earth orbit that GPS receivers use to provide three-dimensional location (latitude, longitude, and altitude) plus precise time.  The GPS system is composed of 3 main segments: Space Segment, Control Segment and User Segment. 

The GPS Space Segment includes twenty-four  to thirty-two satellites that orbit the earth in medium earth orbit MEO.  These satellites are referred to as the GPS Constellation, and they are orbiting once every 12 hours.  They are not geosynchronous, they travel at over 7,000 mph.  GPS satellites are solar powered but have battery reserve for when they are in the earth’s shadow. They are placed so that at any given time there are at least 4 satellites ‘visible’ from any point on earth.  Small rocket boosters on each satellite keep them flying in the correct path.   The satellites last about ten years until all their fuel runs out. 

GPS Satellites are not communications satellites.   Geostationary or communications satellites use a higher altitude 22,300 miles above the equator.  These satellites are used for weather forecasting, satellite TV, satellite radio and most other types of global communications.  At exactly 22,000 miles above the equator, the earth’s force of gravity and centrifugal forces are canceled and are in equilibrium. This is the best location to place a stationary satellite.   The earth rotates at about 1,000 miles an hour, and because of their high earth orbit the geostationary satellites need to travel at about 7,000 mph to maintain position.  This is just about the same speed as GPS satellites, but since earth-synchronous satellites are 10,000 miles further away they don’t move relative to the earth. 

The GPS Control Segment is composed of Master Control Station, an Alternate Master Control Station, and a host of dedicated and shared Ground Antennas and Monitor Stations that work together to ensure the satellites are functioning to specification and the information they beam down to earth is accurate. 

The GPS User Segment includes of GPS receivers  taking the shape of devices and , laptops, in-car navigation devices and hand-held tracking units along with the people that use them, and the software applications that make them work.  

GPS receivers calculate position by precisely timing the signals sent by GPS satellites.  This data includes the time the message was transmitted, precise orbital information (the ephemeris), and the general system health and rough orbits of all GPS satellites (the almanac). 

Keep in mind that there is a fundamental difference between smartphone GPS Tracking and GPS Navigation.  GPS cell tracking is typically related to someone keeping records of either real-time or historical smartphone  location, while Navigation deals with the handset  user figuring out how to get from point A to point B.  Neither use works without some sort of third-party software application.

A very good software package that includes  remote control of smartphone settings, and combines Cell Phone Tracking  with SMS text message, Call Log,  MMS multi-media message monitoring, and a web account for storage and review is PhoneBeagle.

Global Satellite System Frequently Asked Questions

Why does GPS receiver only work outside?
GPS satellites are positioned in their orbits to be sure that from any point on earth there are at least four satellites visibile at any given time. Although they use radio signals, the signal needs a clear of site to the receiver. If the GPS satellite drops behind the horizon, or a building, or even heavy cloud cover, the radio signal may not reach the receiver.  

What do the satellites do?
The GPS satellites are broadcasting the time. Both the satellite and the GPS receiver use atomic clocks for extreme accuracy.  By comparing the difference between the time given by the satellite and the time in the GPS receiver, it can calculate the distance from the satellite.

How do GPS satellites know their location?
The satellites keep position stored internally in calculated tables. But satellites can deviate off course over time. To correct this, the satellite communicates with ground stations positioned around the world. Each time it touches base with the ground stations, the satellite adjusts its internal location tables.

Does a GPS receiver transmit information back to the satellite?
No, they don’t do that. GPS equipped mobile phones will transmit data but it isn’t going back to the satellite.

These satellites may then send out signals back to the earth. These signals can be received by a cellular phone with a GPS system. These signals will be processed to provide a report on a particular location.The more signals that a unit will receive from the satellites, the more accurate the report will be about the position.

Advantages of Cellular GPS Phone with GPS tracking

There are some people who are quite hesitant with the advent of this technology. They think that privacy may be easily affected by such creations.However, one cannot deny that there are of course certain benefits that GPS will fully serve to the people. A Cellular GPS Phone is very useful in emergency situations. In case of the emergency such as a road accident, a 911 call can be easily made through any cellular phone.

However, people will not always know their precise location while they are traveling, especially in such a stressful situation. Thus, the GPS can facilitate easily the 911 crew in pinpointing the precise location of the accident.If you want to gain work safety ,you can try a GPS tracker .

The GPS is also particularly useful for the defense system of any country. It can facilitate more the authorities in tracking and catching suspects and culprits that can threaten the society. This is even more important considering the constant terror threat today.As regards the people who fear for their privacy, there are recent measures that can make them feel more at ease with the GPS technology.

There are certain significant laws that have been passed to ensure the protection of privacy.

Those people who have cellular phones with GPS system can be protected from release of any physical tracking. The information will only be given out if the owner consents, save for the purpose of 911 emergency calls.These measures will make sure that the benefits of GPS will be enjoyed by society without infringing on the right to privacy of anybody. Owning a high-tech cellular phone is a very good thing as it makes the world smaller for you and your love ones. So the next time you consider purchasing a phone for you or your family, get one that is a cellular GPS phone.
