DEVELOPMENT OF REAL-TIME KINEMATIC (RTK) POSITIONING SYSTEM FOR A ROVER

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

GNSS plays a crucial role in terms of its military and civil applications. With the advancement of GNSS, positioning and navigation techniques are becoming significant. Real-time Kinematic is a complex technique that uses GNSS carrier-based positioning. It is more precise than code-based positioning. Its basic aim is to reduce and remove errors in positioning system for base and rover stations. Currently common available systems are not addressing the scenarios where high-precision positioning is required. GPS with accuracy will provide significant improvement in precise positioning. This project required to develop a base station with known coordinates as a reference that acquires raw data through a GPS receiver. Base station then calculates the error in its position and transmits correction in real-time to rover station for application and determination of precise position. In military, almost all target acquisition operations, reconnaissance, weapon guidance systems, and war plans require accurate data, whereas, civil applications includes autonomous industry, aviation industry, and robotics.

Project Objectives

This Project is envisaged to provide a proof of concept that the actual position of the rover can be achieved by applying corrections transmitted by base station implementing positioning technique. Project objectives include:

1. Extensive study of RTK technique.
2. Selection of hardware
3. Integration of hardware components
4. Implementation of RTK corrected system on rover
5. Compilation and evaluation of RTK corrected results

Project Implementation Method

This project is based on positioning technique in which the actual location of the rover can only be known by implementing corrections provided by the base station. First of all, concept of GPS signal and working of GPS is to be understood. After this, by comprehensive studying the RTK positioning system and selecting the hardware we will be able to develop required hardware. Stations are interfaced with the software and a communication link is also established between both stations. Base station will have known coordinates that will be compared with the received coordinates by the GPS satellites. Then it will calculate the error correction and will transmit it via communication link to the rover. Then, rover will use those error correction to calculate its coordinates in real-time and also transmit back its position to base station. Next, this system will be tested in various situations for comparison and compilation of results.

Benefits of the Project

1. This project will provide more accurate results which is beneficial for surveillance.
2. It can be used for acquisition/neutralization of static/mobile targets that can be utilized in military.
3. It can be used for land surveying as well as for hydrographic survey.
