A study on compatibility and interoperability among multi- GNSS

PDF Full Text


Background: During the last decade replenishment and modernization of 2 global satellite navigation systems are witnessed. Development and deployment of another 2 global navigation systems are also observed. 2 regional satellite navigation systems are emerging fast along with them. Now there are more than 120 satellites available and dedicated for navigation purpose. This situation is termed as ‘Multi- GNSS’. ‘Multi- GNSS’ can provide uninterrupted position solution under constraint conditions to the users. But for using ‘Multi- GNSS’ more effectively and efficiently users should properly investigate the issues of interoperability and compatibility among the systems. This paper will address this issue of interoperability and compatibility between different GNSS systems for having the full benefits of using all the systems together.
