A Short Intro To Mobile Phone GPS Tracking

Throughout this discussion consider that there is a fundamental difference between cell phone GPS Tracking and Navigation. GPS phone tracking is usually associated with 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. Just because a cell phone has GPS doesn?t mean that it can easily be used as a navigation device. Just like cell tracking , navigation requires third-party software.

Much of the discussion dealing with cell tracking, mobile GPS and cell phone track software could be helped by a GPS Satellite primer.

GPS satellites broadcast signals from space that GPS receivers use to determine three-dimensional location (latitude, longitude, and altitude) plus precise time. GPS stands for Global Positioning System and is a system that is made up of 3 primary segments: Space Segment, Control Segment and User Segment.

The GPS Space Segment is comprised of twenty-four to thirty-two satellites that orbit the earth in medium earth orbit MEO. These satellites are also known as as the GPS Constellation, and they are orbiting twice a day. They are not geostationary, but rather move at over 7,000 mph. GPS satellites are solar powered but have battery reserve for when they are on the dark side of the earth. They are placed so that there are at least 4 satellites ?visible? from any point on earth. Small rocket boosters on each satellite keep them properly positioned. The satellites have a lifetime of about 10 years until all their fuel runs out.

GPS Satellites are not communications satellites. Geostationary or communications satellites are parked in space 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 gravitational force and centrifugal forces are offset and are in equilibrium. This is the ideal location to park a stationary satellite. The earth rotates at about 1,000 miles an hour, and because of their high earth orbit the geo-synchronous satellites need to travel at about 7,000 mph to keep position. This is approximately the same speed as GPS satellites, but since stationary 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 numerous dedicated and shared Ground Antennas and Monitor Stations that work together to make sure the satellites are working to specification and the information they beam down to earth is accurate.

The GPS User Segment is composed of 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 programs that make them function.

GPS receivers often take longer to become ready to use after it’s turned on because it must acquire some basic information in addition to capturing GPS satellite signals. This delay is sometimes caused when the GPS cell phone has been turned off for days or weeks, or has been transported a significant distance while unused for. The GPS must update its almanac and ephemeris data and store it in memory. The GPS almanac is a set of data that every GPS satellite transmits. When a GPS receiver has current almanac data in memory, it can capture signals and find initial position more quickly.

If satellite signals are not obtainable, or accuracy is less important than battery life, making use of Cell-ID is a good alternative to GPS mobile phone tracking. The position of the handset may be computed by the cell network cell id, that determines the cell tower the cellphone is connected to. By having the position of this tower, then you can know roughly the place that the handset might be. Still, a tower can cover an enormous area, from a couple of hundred meters, in higher populationdensity zones, to a few kilometers in lower density areas. For this reason location CellID precision is less than than GPS accuracy. Even so location from CellID still supplies a very useful substitute.

How To Track A Cell Phone with GPS tracking, mobile GPS and mobile phone tracker software applications are unquestionably drawing focus from potential customers, phone businesses and software coders. At present, mobile communications usually means more than purely making a phone call while moving. The most up-to-date mobiles include GPS location functions to track mobile phone location. These functions, together with others such as SMS message, online accessibility and also the ability to apply other software programs make smartphones remarkable gadgets. Some third-party software applications do more than only GPS.

To help track a mobile involves a number of major methods of formulating cell phone location. GPS (Global Positioning System/Satellites), Triangulation, and CellID. Every one of these technologies convert mobile phones into mobile tracking devices. These kinds of systems can be viewed as Network Based, Handset Based or a Hybrid solution. GPS location is Handset based since it involves software placed on the mobile phone combined with GPS hardware. Triangulation and CellID are Network Based since they make use of the equipment and information from the cellular provider. Hybrid techniques combine approaches to make best use of available information and also to help make perform faster. There is a basic difference between cell phone GPS Tracking and Navigation. GPS cell tracking is usually associated with someone keeping records of either real-time or historical cell phone location, while Navigation deals with the mobile phone user determining how to get from point A to point B. Just because a mobile phone has G

PS doesn?t mean that it can easily be used as a navigation device. Just like cell tracking , navigation requires third-party software.

GPS on cell phones is what people commonly consider when checking out locating mobile phones. GPS (Global Positioning System) using satellites is the most well-known and more accurate technology of tracking. However, GPS demands satellites to be in direct line of site from the handset. It doesn’t work as well indoors or in dense urban centers. In the event that the cell phone is in a building, for example your office, mall, or often riding in a car the signals might not get to the smart phone. Sometimes dense cloud cover and heavy foliage interferes with signals. Some mobile phones can store the last known GPS position, others might not.

An additional issue with handset GPS location will be the possibility of battery drain. It could be important to have the ability to remotely change the frequency acquiring GPS position. Picking real-time or periodic sampling influences both the resolution of determining position as well as how long the battery will last.

Smartphone GPS Tracking Basics

Throughout this discussion keep in mind that there is a basic difference between handset GPS Tracking and Navigation. GPS mobile phone tracking is typically related to a third-party keeping records of either real-time or historical smartphone position, while Navigation deals with the handset user determining how to get from point A to point B. Just because a smartphone has GPS doesn?t mean that it can easily be used as a navigation device. Just like phone tracking, navigation requires third-party software.

A few important technical features and functions related to GPS cell phone tracking to think about include: Tracking Application “Persistence”. The tracking software on a cell phone typically must be enabled by the user. Depending on the smartphone, the application may persist – remaining enabled when the phone is turned on after having been turned off. This feature can be particularly handy if mobile phone tracking is relevant and you do not want to instruct the person using the phone to turn tracking on and off. Another issue relevant to Tracking Application “Persistence” and cell phone GPS tracking is the potential of wasting the battery. It is important to be able to remotely adjust the frequency of taking GPS position. Choosing real-time or periodic sampling affects both the accuracy of finding position as well as how long the battery will last. One typical means of controlling battery and data use is Passive Tracking. Some mobile phone GPS tracking devices will record location data internally so that it

can be downloaded when convenient. Also known as “data logging,” it can keep position data even when the device has traveled outside the wireless network. Passive tracking is not a universal feature built-in to standard mobile phone, but the hottest mobiles tend to have Passive tracking ability.

A lot of the discussion surrounding cell tracking, cell phone GPS and mobile phone tracking software could be helped by a GPS Satellite primer.

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

The GPS Space Segment incorporates 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 geostationary, they travel at over 7,000 mph. They are solar powered but have battery backup 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 properly positioned. The satellites have a lifetime of about 10 years until all their fuel runs out.

GPS Satellites are not communications satellites. Geostationary or communications satellites are parked in space 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 offset and are in balance. This is the best location to park a stationary satellite. The earth rotates at about 1,000 miles an hour, and because of their high earth orbit the earth-synchronous satellites need to move at about 7,000 mph to sustain position. This is just about the same speed as GPS satellites, but since stationary satellites are 10,000 miles further away they don?t move relative to the earth.

The GPS Control Segment made up 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 make sure the satellites are working to specification and the information they beam down to earth is accurate.

The GPS User Segment is comprised of of GPS receivers taking the shape of mobiles 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 function.

GPS receivers determine location by precisely timing the signals sent by GPS satellites. This information 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).

Another way of formulating mobile phone position is Triangulation or Mobile Location Services (MLS). Cell Tower Triangulation utilizes signal analysis data to compute the time it takes signals traveling from the cellphone to a minimum of three cell towers to calculate location.

With Mobile Location Services (MLS), the GSM cellular network provider utilizes triangulation algorithms to estimate the location of the mobile phone, its accuracy is proven to be less than than that of GPS. MLS is also impacted by factors similar to GPS in the sense of the barriers impeding signal strength and the density of GSM towers to assist in the triangulation effort. In remote areas position accuracy may be off as much as a mile.
