About GPS Vehicle tracking system: Technologies involved in a Tracking system and How it works?

Modern technology is making fleet management more efficient and effective in addition to adding to vehicle safety and maintenance. Needless to say these systems are a considerable improvement in fleet management which has always been plagued by inaccessibility to driver and vehicle performance till after the fact.

Technologies Involved

• GPS – Global Positioning System

Allow GPS receiver to determine its exact POSITION in longitude and latitude, velocity, direction etc.

• GSM – Global System of Mobile

Allow this POSITION information to be sent to central control room as

SMS or GSM data call

• GPRS – General Packet Radio Service

Allow transfer of multimedia content like photograph to central control room or other mobile unit

• GIS – Geographical Information system

City maps with technical information which allow converting the POSITION information into possible address, street or place.

How does GPS work?

Each GPS satellite transmits radio signals that enable the GPS receivers to calculate where its (or your vehicles) location on the Earth and convert the calculations into geodetic latitude, longitude and velocity. A receiver needs signals from at least three GPS satellites to pinpoint your vehicle's position.

GPS Receivers commonly used in most Vehicle tracking systems can only receive data from GPS Satellites. They cannot communicate back with GPS or any other satellite.

A system based on GPS can only calculate its location but cannot send it to central control room. In order to do this they normally use GSM-GPRS Cellular networks connectivity using additional GSM modem/module.

IMPORTANT POINTS

• GPS Receiver can communicate (receive and send data) to GPS Satellites

WRONG, GPS Receiver can only receive data and cannot send data to Satellite (s)

• GPS Satellites know the position of your GPS receiver mounted on vehicle

WRONG, GPS satellites do not know the position of a GPS Receiver. GPS Receiver calculates its position using data from 3-4 satellites and no single satellite knows the calculations done by GPS receiver or its position.

• We need to pay GPS Satellite Company for enabling GPS receiver to receive data

WRONG, GPS Satellite service is freely available throughout the world; anyone anywhere can receive GPS data by buying any off-the-shelf GPS receivers.

• GPS Satellites are standard satellites like for Television broadcast, VSAT etc.

WRONG, GPS satellites are different satellites and can only send small and week radio signals to earth.

What is Automated Vehicle Location (AVL)?

AVL systems are computer-based vehicle tracking systems that use a positioning system-GPS (Global Positioning System), GSM (Global System of Mobile) and GIS (Geographical Information System). Vehicle locations are transmitted at regular intervals to dispatch center, where "GIS map matching" software convert it into location and address on map for decision making.

GPS $159 This reference and handbook describes theory, algorithms and applications of the Global Positioning System (GPS/Galileo). It is primarily based on source-code descriptions of the KSGsoft program developed by the author at the GFZ in Potsdam. The theory and algorithms are extended and verified for a new development of a multiple functional GPS/Galileo software. Besides the concepts such as the unified GPS data processing method and the numerical solution of the variation equations, as well as the general ambiguity search criteria reported in the first edition, there are several highlights reported. Such as the equivalent principle and its applications, the theory of independent parameterisation, the diagonalisation algorithm, etc. Mathematically rigorous, the book begins with the basics of coordinate and time systems and satellite orbits, as well as GPS observables, and deals with topics such as physical influences, observation equations and their parameterisation, adjustment and filtering, ambiguity resolution, data processing, and the determination of perturbed orbits.

Snooper (Global Positioning System) $70.1 High Quality Content by WIKIPEDIA articles Snooper is a UK brand of GPS navigation systems and speed camera detector systems for cars, HGV vehicles and caravans. Snooper is owned by satellite navigation systems manufacturer Performance Products Ltd. based in Runcorn, Cheshire, Northwest United Kingdom. Performance Products is a whollyowned subsidiary of Cobra Electronics. A GPS navigation device is any device that receives Global Positioning System (GPS) signals for the purpose of determining the devices current location on Earth. GPS devices provide latitude and longitude information, and some may also calculate altitude, although this is not considered sufficiently accurate or continuously available enough (due to the possibility of signal blockage and other factors) to rely on exclusively to pilot aircraft. GPS devices are used in military, aviation, marine and consumer product applications. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.

Accuracy of GPS Precise Point Positioning $97.19 GPS is effectively used in science and engineering since the release of official IGS precise orbits in 1994. Various surveying and processing methods are available for GPS, and the accuracy level depends on the method used. It is useful to predict the accuracy of GPS prior to a field survey for the purposes of network design. Today, accuracy prediction formulas are available for relative positioning that requires two or more GPS receivers. Precise Point Positioning (PPP) from NASAs GPS software GIPSY revolutionized the GPS processing since it provides methods leading to mm positioning without a need of a reference station. GIPSY user community is growing rapidly and at this instance it would be good to provide a tool assessing the acuracy of PPP. This book targets both practitioners and researchers. It should also be a useful guide for the relative positioning users for comparing the results derived here with those of published previously. The literature review and the interim analysis results made availeble through tables for hands on applications should be interesting for graduate students.
