Project Overview
The project aims to develop a multi channel multi constellation GNSS receiver which can acquire /track and provide positioning solution in stand alone and hybrid constellation mode for follwing multiple MBOC modulated GNSS signals under weak signal condition
* NavIC SBOC(6,1,1/11) modulated L1 SPS signal
* GPS TMBOC(6,1,4/33 and complete MBOC(6,1,1/11) modulated L1C civil signal
* Galileo CBOC(6,1,1/11) modulated E1 civil signal
* BDS QMBOC modulated B1 signal
* Receiver should explore vectorized DLL and vector frequency lock loop for tracking weak signal (upto 15 dB/Hz) and to track signal under multipath condition.
* Developed reciever should hacve the capability of acquiring signal under weak signal conditions (acquisition below 25dB-Hz C/No) and the performance of the implemented reciever is to be evaluated in weak signal condition such as in urban and sub urban canyons.
* Other weak signal acquistion and tracking algorithms can also be explored to meet the specifications
* The software of receiver to be preferably written in C/C++ , HDL, MATLAB languages
