Global Positioning System B.tech Seminar Topic for ECE Final Year Students

This paper discussed about a special-based global navigation satellite system, Global Positioning System (GPS).  GPS satellites are maintained by United States Government and it can be used by any user around the world with a GPS receiver with some technical limitations.  In order to address and overcome the problem of previous navigation system, the GPS project was evolved in 1973.  During that time GPS was running with 24 satellites.  

Overview:

Global Positioning System (GPS) receiver receives the signals from GPS satellites which are located high above the earth and then calculates its position by clearly timing those signals. Each satellite continually transmits the message with the information included like time of the message transmission, clear orbital information and system health of all GPS satellites.

Many civilian applications uses absolute location, relative movement and time transfer components of a Global positing system. Clock synchronization, Cellular telephony, Geotagging, GPS Tour and Navigation are the most important GPS applications for civilian.  Satellite clock error, Atmospheric error and Receiver clock error are the three sources of errors in GPS.

 Both Ionospheric error and Tropospheric error are parts of atmospheric error.  Space segment, control segment and user segment are three segments consisted by a GPS element. GPS works in microwaves bands. GPS unit have few problems when operate it in rain, forest, jungle, deep canyons, and inside automobiles. Actuation of Gold code helps to demodulate and decode GPS satellite signals. Every GPS continuously broadcasts a navigation message with rate 50 bps. Position calculation, GPS receiver clock and shouting from the stars are the main three basic concepts of GPS.

Conclusions:

Navigation, Target tracking, Missile and projectile guidance are the most important GPS applications for military.  GPS allows military soldiers to find objectives in the dark and coordinate troop and supply movement accordingly.  GPS helps to track ground and air targets. Military aircrafts uses GPS to find targets. GPS allows accurate targeting of military weapons like ICBMs, cruise missiles and precision-guided munitions.

CSE Mini Project Topic on GSM Modem Based SMS Gateway with Project Report

AT COMMANDS are used to design a SMS gateway that can easily communicate with the GSM modem. For proper interaction this system will have a user friendly graphical interface. This in turn will connect with the modem using protocol like HTTP and others.

This system is highly advanced and it is designed with several objectives like to receive and send SMS to mobile device using the computer system.

In this system the computer will be connected to the GSM modem in order to provide smooth efficiency of message transferring. It will also enable to study the AT commands as well as their implementation in GSM modems.

Another aim of this system is to create a GUI based application for receiving and sending messages. It also helps to store messages in the computer’s memory. 

To receive and send message using the GSM modem SMS gateway is the most effective mean and we can send SMS only from those computers that are connected to a GSM mode. At commands are used for this purpose and recently the study and its implementation is done successfully.

Receiving SMS is only possible if we have GSM modem and usually mobile phones do not work on this formula of GSM modem. For more features enhancement is necessary to made in the GUI system. We can now send and receive MMS and also add contact details, etc.

Remote Notice Board Using GSM With SMS Full Project Report

Introduction to Remote Notice Board Using GSM With SMS Project:

The world is shrinking with time because today people from all over the world can easily communicate with one another in just a matter of seconds. Digital techniques of communication are the main brainchild behind this success and with the passage of time these techniques are successfully developing more and more.

Advancement control and communication has become important in all parts of the world. The use of cellular technology – mobile phones have increased drastically in the past years.

The main motto of smart Notice Board Using GSM project is to use mobile phones to receive the message and then send it for display to notice board. This project is designed with the concept of micro-controller and it can be used to control remote notice board.

The heart of the project is P89C52RD2BN. Here the cellular technology is considered for sending message to the notice board. The mobile used is of GSM technology.

The international roaming capability is the main strength of GSM which means it ensures seamless service for the customers. Apart from that it also enable high quality speech, digital experience, call waiting and forwarding services and freedom of using universal mobile phones. SMS is a service of GSM technology by which data can be received and send easily from one handset to another.

The message can consist of alpha numerical combination, words and numbers. SMS service is one of the widest using techniques and it is meant especially for those who have hearing or speech problems. 

The best part is that if you are outside the coverage of the GSM area then the SMS will be stored for you and once you enter the coverage area you will receive it then and there. This will also help you to be aware about the security system of your office and home.

 Functional Block Diagram of the GPS Navigation Robot

The block diagram of Final Year Mechanical Project clearly shows the functional working of gps that is here the set point (current position) is compared the first waypoint. Once the destination is reached the program memory enqueue the second way point and so on. If the designated waypoint is not reached again it checks till the destination is reached. 

Performing the Navigation Using GPS and Camera:

The effective way of using adaptive robotic technology is performing the complex operation simultaneously to do the desired operation. Similarly we have performed the simultaneous operation by performing both obstacle avoidance and positioning using stereo camera and gps sensor respectively. The main advantage of performing this GPS Navigation Robot operation is maximum nearness error can be avoided that is created during real time positioning. The block diagram clearly shows how the navigation is performed.

Robotics Final Year Project Ideas and Topics

Constructional Working of Robotics:

Electronic Engineering ECE Approach:

Camera:

In our Robotics Final Year Project we have two cameras

a) C-MOS camera sensor

b) Stereo camera

          The C-MOS sensor camera is placed at the center of the bot and the stereo camera is placed at the center of the bot and the stereo camera is placed at the top of the bot. the camera is tilt to an angle to make the projection perfectly projected to the center of the object.

The C-MOS camera is used to perform more specifically for the lane detection. It is used because of its very high sensitivity to light, low power consumption and low cost. The output is digital, so it is directly fed to the controller to take the action. The functional block diagram shows the importance of camera action.

Technical Features of the Robotic Camera:

The Image processing and Image acquisition is performed by the on-board micro processor and the result of stereo and C-MOS camera is stored in SRAM (Static Random Access memory) and DRAM (Dynamic Random Access Memory) respectively.

The lane following is pre processing method, so the sample of images are pre loaded to the SRAM and it’s been cross checked by the controller and necessary action is given to the end effector. 

          The Dynamic image processing is carried out by using stereo camera where the self-windowing algorithm is used for real time variation. It is been stored in DRAM and synchronously signal is given to controller to perform the end- effector action.

Block diagram of the robotic project idea clearly show the importance of two cameras.

Mechanical Engineering Projects on Robotics

The computational robotic feature was developed using a mechanical system engineering approach with emphasis placed on the understanding the inter-relationship between system components and on maximizing the overall system performance.

The Mechanical Engineering Project development of fully autonomous is a very complex task which holds the consideration of several factors. First, the appropriate view of providing and utilizing autonomy must be determined for each application. For example, the sensors used in this robotic project for image analysis and global positioning is high a time-variants, so this will directly create impact on any set of tasks designed.

Here we tried to manipulate the entire operation carried out by the Robotics Engineering itself that is it has its own capacity to take any decision under any environment without interference.

The integration is very difficult because it requires the assembly of many complex sub systems into a high degree of interconnection and synchronization.

From a Mechanical and Electronic engineering perspective, a well-defined architect provides the underlay framework for achieving reliable maintainable cost-effective system. N Such architecture does this by enabling methods coherently integrating diverse physical, functional and disciplinary sub-systems.
