Comparison of DOP of GPS and Galileo in the South Asian region

Dilution of precision is one of the most important parameter to consider for satellite navigation. With the existent full operational US operated GPS system the position can be calculated anywhere in the world. The upcoming European Galileo system is also a strong contender for the efficient calculation of position determination. Comparing both the GPS and Galileo in terms of GDOP and PDOP and also number of visible satellites the Galileo system has been proved a better version between the two. Simulation with the help of MATLAB GUI the overall comparison has been carried out for the three countries of South Asian region.
