TAIP (trimble ASCII interface protocol)ĭesigned specifically for vehicle tracking applications. TSIP (trimble standard interface protocol)Ī binary packet protocol that allows the designer to configure and control the GPS receiver for optimal performance in any number of applications. NMEA provides direct compatibility with other NMEA-capable devices such as chart plotters and radars.
Some popular protocols for GPS receivers are: NMEA 0183Īn industry-standard protocol common to marine applications defined by National Marine Electronics Association (NMEA), USA. This is a satellite service providing additional correction information to the GPS receiver in order to increase its accuracy.īefore purchasing a GPS receiver, it’s good to know the protocols supported by it. If accuracy is important, you need GPS with a wide-area augmentation system (WAAS) capability.

To obtain accurate information, the satellites and the receiver use very accurate clocks, which are synchronised so that they generate the same code at exactly the same time. GPS determines the distance between a GPS satellite and a GPS receiver by measuring the amount of time taken by a radio signal (the GPS signal) to travel from the satellite to the receiver. 2: Circuit of a GSM and GPS based vehicle tracking system GPS receiver converts the received signals into position and estimates time and some other useful information depending on the application and requirements. A minimum of four satellites may be required to compute the four dimensions of X, Y, Z (latitude, longitude and elevation) and time. All the GPS satellites transmit radio signals, which are then captured by a GPS receiver and used to calculate its geographical position. So they maintain exactly the same position with respect to the earth below them. These satellites are geosynchronous with an orbital period that is the same as the Earth’s rotation period. The GPS consists of satellites that orbit the earth. GPS receivers are popularly used for navigation, positioning, time dissemination and other research purposes. It provides location and time information in all weather conditions, anywhere on or near the Earth. GPS is a space-based satellite navigation system. It reduces vehicle abuse and ultimately results in significant cost-savings for individuals, fleet owners and the like.īefore delving into the detailed working of the project, let’s discuss some basics of GPS and GSM technologies. You can also use it to keep tab on your driver. An SMS will inform you whether the vehicle is stationary or on the move.ĥ.
#Itracking gps install#
You can easily install it in any vehicle such as cars, boats and motorbikes. The device ensures vehicle security and smooth fleet management.Ĥ. It can be used for trucks carrying valuable goods, to keep track of the status of delivery and location of the truck at all times.ģ. You can locate your stolen vehicle easily using your mobile without any extra cost.Ģ. 1: Block diagram of the GSM and GPS based vehicle tracking system Applications and benefitsġ. 1 shows the block diagram of the GSM and GPS based vehicle tracking system. Whether you own a company with a fleet of hundreds of vehicles or you have expensive piece of equipment and you want to keep an eye on them, this tracking system can inform you of the status without you having to be actually present on the site.įig. This system allows you to track your vehicle anytime and anywhere. You will automatically get the location of the vehicle in the form of an SMS (short message) on your mobile phone. After this installation, you can easily track your vehicle using your mobile phone by dialling the mobile number of the SIM attached to the GSM modem. The system can be mounted or fitted in your vehicle in a hidden or suitable compartment. Component list for GPS based vehicle tracking system GSM modem with a SIM card used here implements the same communication technique as in a regular cellphone. This project uses only one GPS device and two-way communication is achieved using a GSM modem. This is a cheaper solution than a two-way GPS communication system wherein communication is done in both ways with GPS satellites.
