GPS receivers are GPS tracking device or GPS tracker as the user segment.
To find out the GPS positioning of any object, we have to follow some basic steps or process initially, the signal of time is sent from a GPS satellite at a given point. Thereupon, the time difference between GPS time and the point of time clock which GPS receiver receives the time signal will be calculated to determine the distance from the receiver to the satellite. The same process will be done with three other available satellites in the orbit. It is very easy to calculate the position of the GPS receiver from distance to three satellites. In fact, the position determined by means of this method is not accurate, for there is an error in determined distance between satellites and a GPS receiver, which generates from a time error on the clock incorporated into a GPS receiver. For a satellite, an atomic clock is incorporated to generate on-the- spot time information, but the time generated by clocks incorporated into GPS receivers is not as precise as the time generated by atomic clocks on satellites. Here, the fourth satellite comes to play its role: the distance from the fourth satellite to the receiver can be used to compute the position in relations to the data of position determined by distance between three satellites and the receiver, hence it reduces the margin of error in position accuracy. We can determine where we are at by determining distance from two given points, and the GPS tracking is the system that can be illustrated by multiplying given points and replacing them with GPS satellites.
GPS satellites broadcast having beams in two carrier frequencies; L1 and L2. L1 frequency having 1,575.42 MHz and L2 frequency having 1,227.60 MHz. There are two types of code of beams C/A and P code. Beams that can be used only by the US military force are encoded in P (Precise) code and the Beams that can be accessible to the general public are encoded in C/A (Coarse/Acquisition) code. Coarse/Acquisition (C/A) code consists of identification codes of each satellite and is broadcast together with navigation messages. The data present in the orbit of each satellite is called the ephemeris, and the data of orbit of all the satellite is called the almanac. The navigation messages are broadcast at a rate of 50 bits/second. Utilizing this collection of data, GPS receiver determines the distance between satellites and the receiver in order to generate position data. The ephemeris provides the precise orbit for the satellite itself, which can be used to generate precise location of the satellite, necessary information for calculating position information. It is the locale data that is used only by each of the GPS satellites with exclusive identification number. The almanac can be regarded as simplified ephemeris data and contains coarse orbit and status information for all satellites in the network. It is used to locate available satellites in order a GPS receiver to generate current position and time. It takes 12.5 minutes to receive all the almanac data.
L1 signal from the GPS satellites is phase-modulated in C/A (coarse and acquisition) code, which is the pseudorandom code. This code is also called as pseudorandom noise code, which is also known as a Gold code.
Navigation message consists of 25 frames, each of which includes 5 subframes of 300 bits each. The data length of 1 bit is 20 ms, and thus, the length of each subframe is 6 seconds, and each frame is a grouping of 1,500 bits of information with the frame length of 30 seconds. Since navigation message consists of 25 frames, this would add up to the message length of 12.5 minutes (30 seconds x 25=12.5 minutes). GPS demands 12.5 minutes to read all the essential set of data, essential condition for positioning, when preparatory power activation takes place. The GPS receiver is deserving of storing this set of data gained in the past internal backup battery, and it reads out the set of data when power reactivation takes place, hence immediately starting to receive GPS position.
The ionosphere is a portion of the upper atmosphere, it is between the thermosphere and the exosphere. When GPS signals pass through this ionosphere, the propagation velocity of the GPS signal goes slower, hence causing propagation error.
The troposphere layer is the lowest portion of the atmosphere of earth. In this layer, it is provoked GPS position error.
GPS signal is not liberated to reflection when it hits on the ground, structures and many others. This phenomenon is called multi-path propagation, and it is one of the causes of GPS position errors.
Dilution of Precision (DOP) is the value that shows the degree of degradation (DOD) of the GPS positioning accuracy. The smaller the value is, the higher the positioning accuracy is. This value of DOP depends upon the positions of the GPS satellites tracked for positioning. If the tracked satellites elaborate over the earth, the positioning accuracy would become higher i.e. positioning accuracy depend upon the tracked satellites and if the positions of tracked satellites are disproportionate, the positioning accuracy would become lower.
State of reception of GPS depends upon the strength of GPS signals. If the strength of signal is greater than the reception status will be more. Whereas the reception status would become unstable when the GPS signal became weaker, due to obstacles or noise sources in the vicinity of a GPS receiver.
State of reception of GPS depends upon the strength of GPS signals. If the strength of signal is greater than the reception status will be more. Whereas the reception status would become unstable when the GPS signal became weaker, due to obstacles or noise sources in the vicinity of a GPS receiver.State of reception of GPS depends upon the number of satellites tracked for positioning. If the number of the tracked satellites is great, GPS positioning becomes greater, but if there were a fewer satellites tracked for positioning, it would be difficult to generate GPS position. This information is all about the GPS and GPS tracking system. GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS.
GPS is an important system as it helps you to figure out where you are and where you are going when you are traveling from one place to another. Navigation and positioning are important but arduous activities, which GPS system makes it easier. GPS units receive signals from the satellites that they use to determine location. GPS system can figure out your position in to three dimensions—latitude, longitude and altitude. The most interesting and remarkable thing about GPS is that the satellite navigational information is available to anyone, anywhere, free of charge. By the way, you need to buy only a GPS receiver to use the data, but it’s a pretty small investment when you realize how much information you can get from this GPS receiver. However, with recent forms of GPS system you may make measurements much better or accurate than cm (centimeter) readings. So, it is big relief with GPS system that you can give or track a unique and specified address to every square meter on the planet. So, these days GPS system can be used into fleets, cars, planes, boats, construction equipment, smartphones, laptop computers.

GPS system offers almost eternal possibilities for high-tech boaters. In fact, GPS system is a wonderful tool to the boaters. Since the 1980s to today, GPS system has been freely available to countries, companies, organizations and to anyone with a GPS receiver. Transportation companies, trucking companies, shipping companies, airlines and car owners all of these use GPS systems to track and monitor the location of trucks, vessels, planes and cars. With the help of GPS system, navigation route can be monitored in the less time as it possible and as accurately as possible. Modern technology improvement has made the use of GPS system very easy unlike in the past. Smart phones and cars can now receive and decode GPS in split seconds with great ease with help of GPS tracking device. The interesting part of GPS is that you do not pay extra charge for easy data and information like exact location.
A GPS tracker is a device, usually carried with the aid of a moving automobile or person, that uses the worldwide positioning device to determine and tune its precise vicinity, and for this reason that of its carrier, at intervals. The recorded area information can be stored inside the monitoring unit, or GPS tracker can be transmitted to a crucial region database, or internet-connected computer, the usage of a mobile (gprs or SMS), radio, or satellite modem embedded within the unit. With GPS tracker, Information monitoring software is to be had for smartphones with gps capability. A gps tracker "song me" essentially incorporates a gps module to receive the gps sign and calculate the coordinates. For records loggers GPS tracker contains large reminiscence to keep the coordinates, records pushers additionally contain the gsm/gprs modem to transmit this statistics to a central laptop both through SMS or through GPRS in form of ip packets. A gps logger virtually logs the location of the tool at regular periods in its internal memory. Cutting- edge gps loggers have either a reminiscence card slot, or inner flash reminiscence card and a usb port. A few gps tracker acts as a usb flash power. This permit downloading of the music log statistics for in addition evaluation in a pc. The track list or factor of interest listing may be in gpx, kml, nmea or another layout. Maximum virtual cameras save the time a photo was taken. Furnished the camera clock turned into reasonably accurate or used gps as its time supply, this time can be correlated with gps log information, to offer a correct location. This will be brought to the exif metadata within the photo record. Cameras with gps receiver built in can immediately produce this sort of geotagged image. In some personal research cases, information loggers are used to preserve music of a goal vehicle. The pi need now not comply with the goal so carefully, and usually has a backup source of information. Statistics pusher is the maximum commonplace type of gps tracking unit or GPS tracker, used for asset monitoring, private monitoring and car tracking gadget. Also known as a gps beacon, this kind of device sends the location of the tool in addition to other facts like velocity or altitude at normal durations, to a decided server, that may save and immediately analyse the statistics. A GPS navigation device or GPS tracker and a cellular phone sit down facet- with the aid of-facet in the identical field, powered by means of the equal battery. At regular durations, the smartphone sends a text message through SMS or GPRS, containing the data from the gps receiver. More modern gps-included smartphones going for walks gps tracking software can flip the smartphone into a records pusher (or logger) tool; as of 2009 open supply and proprietary packages are available for commonplace java me enabled phones, iPhone, android, windows cellular, and Symbian. Maximum 21st-century gps trackers provide statistics "push" generation, permitting sophisticated gps monitoring in commercial enterprise environments, particularly groups that appoint a cellular workforce, including an industrial fleet. Standard gps tracking systems utilized in commercial fleet management have centre parts: area hardware (or tracking tool) and tracking software program. This mixture is frequently called an automatic vehicle place machine. The tracking device is most often hardwiring mounted within the car; linked to the can-bus, ignition system switch, battery. It permits collection of more data, which later receives transferred to the gps tracking server, in which it is available for viewing, in most cases thru an internet site accessed over the net, wherein fleet interest can be viewed stay or traditionally the use of virtual maps and reports. Gps monitoring structures utilized in industrial fleets are frequently configured to transmit place and telemetry enter facts at a set update charge or whilst an occasion (door open/near, auxiliary equipment on/off, geofence border go) triggers the unit to transmit records. Stay gps tracking used in industrial fleets, generally refers to systems which replace often at 1 minute, 2 minutes or five-minute durations, at the same time as the ignition fame is on. A few tracking systems combine timed updates with heading trade prompted updates. GPS statistics pullers also are referred to as gps transponders. Not like records pushers that ship the location of the gadgets at ordinary intervals (push generation), these devices are usually on, and may be queried as frequently as required (pull era). This era isn't always in big use, but an instance of this form of device is a laptop connected to the net and jogging gps. Those can frequently be used in the case wherein the location of the tracker will simplest need to be regarded sometimes e.g. Placed in belongings that may be stolen, or that does not have regular supply of strength to ship records on an ordinary foundation, like freights or packing containers. Pullers are coming in greater common use in the form of gadgets containing GPS receiver. Covert GPS trackers comprise the equal electronics as ordinary gps trackers however are constructed in one of these manner as to look like a normal item. One use for covert gps trackers is for electricity tool safety, these gadgets can be hide within energy device boxes and traced if theft occurs.

A GPS system is a network of satellites which orbit or rotate around the earth. GPS system uses satellites signals to determine a user's position. To be able to apply these satellites signals, we need to know the exact distance that our GPS receiver is from the orbiting satellites to be able to calculate an accurate position. To determine distance of the GPS receiver and satellites, both the satellite and GPS receiver generate the same pseudo code at the same time. The satellite transmits the pseudo code which is received by the GPS receiver. The GPS system is a system. GPS system is made up of three parts which are satellites, ground stations, and receivers. The most and important features of the GPS is to determine your actual location and GPS system gives you the exact or accurate information about time in all-weather condition. GPS system is very useful system, this GPS system can be used for military operations, navy operations, air force, etc. now a day GPS System is also used for civilians to track their vehicles as well as their pets, kids by using personal GPS Tracking devices. The GPS system works in a very effective manner. satellites work as a star in the constellations, where they are supposed to be at any given time. The signals obtained by receivers and are used to determine accurate position, time and speed at the location of vehicles. The GPS system is highly popular for its military uses. The US is the first to developed GPS system in 1960s for their Navy to navigate their ships in the ocean more accurately. The first ever GPS System had the 5 satellites. The ships were allowed to check their location only once in an hour. Today the GPS system has changed totally and have the portable navigation or GPS Tracking devices which can be used in vehicles to give drivers their precise location which is exact enough to navigate roadways. Military operations can also be navigating with highly precision location. since the 1980s, the GPS system have been freely available to everyone with a GPS receiver. The NAVSTAR GPS of US is the only operational GNSS (Global Navigation Satellite System) which is providing positioning data with global coverage. The China has local GPS system which may also expand it globally. Russia have its own GPS system which is known as GLONASS. The Europium have developed its own GPS known as Galileo Positioning System. These are the most interesting facts about GPS. The GPS system includes 24 satellites deployed in space about 19,300 kilometers above the earth's surface. They orbit the earth once every 12 hours at an extremely fast pace of roughly 11,200 kilometers per hour. The GPS satellites are evenly spread out in earth’s orbit so that four satellites are accessible via direct line-of-sight from anywhere on the globe. Each GPS satellite broadcasts or send a message that includes the satellite's current position, orbit, and exact time. A GPS receiver collects the broadcasts from multiple satellites to calculate its exact position using a process called triangulation. Three satellites are required in order to determine a receiver's location, though a connection to four satellites is ideal since it provides greater accuracy. Most GPS devices in GPS System also use some type of location caching to speed up GPS detection. By memorizing its previous location, a GPS device can quickly determine what satellites will be available the next time it scans for a GPS signal.
