A GPS tracking Miami Coral Gables is a device, normally carried by a moving vehicle or person, that uses the Global Positioning System to determine and track its precise location, and hence that of its carrier, at intervals. GPS tracking Miami Coral Gables The recorded location data can be stored within the tracking unit, or it may be transmitted to a central location database, or Internet-connected computer, using a cellular (GPRS or SMS), 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 analyzing the track later, using GPS tracking Miami Coral Gables. Data tracking software is available for smartphones with GPS capability

Types of GPS trackers GPS tracking Miami Coral Gables

Usually, a GPS tracker will fall into one of these three categories, though most GPS-equipped phones can work in any of these modes according to mobile applications installed: GPS tracking Miami Coral Gables

A GPS logger simply logs the position of the device at regular intervals in its internal memory. Modern GPS loggers have either a memory card slot, or internal flash memory card and a USB port. Some act as a USB flash drive. GPS tracking Miami Coral Gables This allows downloading of the track log data for further analysis in a computer. GPS tracking Miami Coral Gables The tracklist or point of interest list may be in GPX, KML, NMEA or another format.

Most digital cameras save the time a photo was taken. Provided the camera clock was reasonably accurate or used GPS as its time source, this time can be correlated with GPS log data, to provide an accurate location. GPS tracking Miami Coral Gables

This can be added to the Exif metadata in the picture file. Cameras with GPS receiver built in can directly produce such a geotagged photograph. GPS tracking Miami Coral Gables

GPS is tracking Miami Coral Gables In some private investigation cases, data loggers are used to keeping track of a target vehicle. The PI need not follow the target so closely, and always has a backup source of data. GPS tracking Miami Coral Gables

Data pushers GPS tracking Miami Coral Gables

Data pusher is the most common type of GPS tracking unit, used for asset tracking, personal tracking and Vehicle tracking system. GPS tracking Miami Coral Gables

GPS tracking Miami Coral Gables Also known as a GPS beacon, this kind of device pushes ("sends") the position of the device as well as other information like speed or altitude at regular intervals, to a determined server, that can store and instantly analyze the data. GPS tracking Miami Coral Gables

GPS tracking Miami Coral Gables A GPS navigation device and a mobile phone sit side-by-side in the same box, powered by the same battery. At regular intervals, the phone sends a text message via SMS or GPRS, containing the data from the GPS receiver. Newer GPS-integrated smartphones running GPS tracking Miami Coral Gables can turn the phone into a data pusher (or logger) device; as of 2009 open source and proprietary applications are available for common Java ME enabled phones, iPhone, Android, Windows Mobile, and Symbian.

GPS tracking Miami Coral Gables Most 21st-century GPS trackers provide data "push" technology, enabling sophisticated GPS tracking in business environments, specifically organizations that employ a mobile workforce, such as a commercial fleet. GPS tracking Miami Coral Gables Typical GPS tracking systems used in commercial fleet management have two core parts: location hardware (or tracking device) and tracking software. This combination is often referred to as an Automatic Vehicle Location system. The tracking device is most often hardwire installed in the vehicle; connected to the CAN-bus, Ignition system switch, battery. It allows collection of extra data, which later gets transferred to the GPS tracking server, where it is available for viewing, in most cases via a website accessed over the internet, where fleet activity can be viewed live or historically using digital maps and reports.

GPS tracking Miami Coral Gables GPS tracking systems used in commercial fleets are often configured to transmit location and telemetry input data at a set update rate or when an event (door open/close, auxiliary equipment on/off, geofence border cross) triggers the unit to transmit data. Live GPS Tracking used in commercial fleets, generally refers to systems which regularly update at 1 minute, 2 minute or 5-minute intervals, whilst the ignition status is on. Some tracking systems combine timed updates with heading change triggered updates. GPS tracking Miami Coral Gables

GPS tracking solutions are recently being used in mainstream commercial auto insurance these are sometimes called Telematics 2.0. GPS tracking Miami Coral Gables

The applications of trackers of this kind include: PERSONAL GPS GPS tracking Miami Coral Gables

  • Law enforcement. An arrested suspect out on bail may have to wear a GPS tracker, usually an ankle monitor, as a bail condition. GPS tracking may also be ordered for persons subject to a restraining order. GPS tracking Miami Coral Gables

  • Race control. In some sports, such as gliding, participants are required to carry a tracker. In particular this allows race officials to know if the participants are cheating, taking unexpected shortcuts, and how far apart they are. This use was illustrated in the movie Rat Race. GPS tracking Miami Coral Gables

  • Espionage/surveillance. A tracker on a person or vehicle allows movements to be tracked. This application is used by private investigators.

  • These devices are also used by some parents to track their children. Some devices can send text alerts to the parents for every unexpected place visited by the child. GPS tracking Miami Coral Gables

  • GPS personal tracking devices are used in the care of the elderly and vulnerable. Devices allow users to call for assistance and optionally allow designated careers to locate the user's position, typically within 5 to 10 meters. Their use helps promote independent living and social inclusion for the elderly. Devices often incorporate either 1-way or 2-way voice communication. Some devices also allow the user to call several phone numbers using pre-programmed speed dial buttons. Trials using GPS personal tracking devices are also underway in several countries for use with early-stage dementia. GPS tracking Miami Coral Gables

  • Some Internet Web 2.0 pioneers have created their own personal web pages that show their position constantly, and in real time, on a map on their website



These usually use data push from a GPS enabled a cell phone or a personal GPS tracker. GPS tracking Miami Coral Gables
  • Sports: the movements of a rambler, cyclist, etc., can be tracked. Statistics such as instantaneous and average speed, and distance traveled, are logged

  • Adventure sports: GPS tracking devices such as the SPOT Satellite Messenger are available that allow the position of a person to be tracked.

    • Solar Powered. GPS is tracking Miami Coral Gables The advantage of some solar powered units is that they have much more power over their lifetime than battery powered units. This gives them the advantage to report their position and status much more often than battery units which need to conserve their energy to extend their life. Some wireless solar-powered units, such as the RailRider can report more than 20,000 times per year and work indefinitely on solar power eliminating the need to change batteries.

    • Animal control. GPS tracking Miami Coral Gables When putting on a wildlife animal (e.g. in a collar), it allows scientists to study its activities and migration patterns. Vaginal implant transmitters mark the location where pregnant females give birth. Animal tracking collars may also be put on domestic animals, to locate them in case they get lost.

    Aircraft trackers GPS tracking Miami Coral Gables

    GPS tracking Miami Coral Gables

    Aircraft can be tracked either by ADS-B (primarily airliners), or by FLARM data packets picked up by a network of ground stations (primarily used by General Aviation aircraft, gliders and UAVs), both of which are data pushers. ADS-B is to be superseded by ADS-C, a data puller. GPS tracking Miami Coral Gables

    Data pullers GPS tracking Miami Coral Gables

    GPS tracking Miami Coral Gables

    GPS data pullers are also known as GPS transponders. Unlike data pushers that send the position of the devices at regular intervals (push technology), these devices are always on, and can be queried as often as required (pull technology). This technology is not in widespread use, but an example of this kind of device is a computer connected to the Internet and running . GPS tracking Miami Coral Gables

    These can often be used in the case where the location of the tracker will only need to be known occasionally e.g. placed in property that may be stolen, or that does not have constant GPS tracking Miami Coral Gables source of energy to send data on a regular basis, like freights or containers.

    Data Pullers are coming into more common usage in the form of devices containing a GPS receiver and a cell phone which, when sent a special SMS message reply to the message with their location.

    GPS tracking Miami Coral Gables contains the same electronics as regular GPS trackers but are constructed in such a way as to appear to be an everyday object. One use for GPS tracking Miami Coral Gables is for power tool protection, these devices can be concealed within power tool boxes and traced if theft occurs. GPS tracking Miami Coral Gables

    A GPS signal contains 3 different types of information: GPS tracking Miami Coral Gables GPS tracking Miami Coral Gables

    • Pseudorandom code GPS tracking Miami Coral Gables is an I.D. code that identifies which satellite is transmitting information. GPS tracking Miami Coral Gables You can see which satellites you are getting signals from on your device's satellite page. GPS tracking Miami Coral Gables

    • Ephemeris data GPS tracking Miami Coral Gables is needed to determine a satellite's position and gives important information about the health of a satellite, current date and time. GPS tracking Miami Coral Gables

    • Almanac data GPS tracking Miami Coral Gables tells the GPS receiver where each GPS satellite should be at any time throughout the day and shows the orbital information for that satellite and every other satellite in the system. GPS tracking Miami Coral Gables


    GPS Signal Errors Sources GPS tracking Miami Coral Gables GPS tracking Miami Coral Gables

    Factors that can affect GPS signal and accuracy include the following: GPS tracking Miami Coral Gables

    • Ionosphere and troposphere delays: Satellite signals slow as they pass through the atmosphere. GPS tracking Miami Coral Gables The GPS system uses a built-in model to partially correct for this type of error. GPS tracking Miami Coral Gables

    • Signal multipath: The GPS signal may reflect off objects such as tall buildings or large rock surfaces before it reaches the receiver, which will increase the travel time of the signal and cause errors. GPS tracking Miami Coral Gables

    • Receiver clock errors: A receiver's built-in clock may have slight timing errors because it is less accurate than the atomic clocks on GPS satellites. GPS tracking Miami Coral Gables

    • Orbital errors: The satellite's reported location may not be accurate. GPS tracking Miami Coral Gables

    • A number of satellites visible: The more satellites a GPS receiver can "see," the better the accuracy. When a signal is blocked, you may get position errors or possibly no position reading at all. GPS tracking Miami Coral Gables GPS units typically will not work underwater or underground, but new high-sensitivity receivers are able to track some signals when inside buildings or under tree-cover. GPS tracking Miami Coral Gables

    • Satellite geometry/shading: Satellite signals are more effective when satellites are located at wide angles relative to each other, rather than in a line or tight grouping. GPS tracking Miami Coral Gables

    • Selective availability: The U.S. Department of Defense once applied Selective Availability (SA) to satellites, making signals less accurate in order to keep 'enemies' from using highly accurate GPS signals. GPS tracking Miami Coral Gables The government turned off SA in May of 2000, which improved the accuracy of civilian GPS receivers. GPS tracking Miami Coral Gables
