Augmentation Methods for GNSS Integrity and Precision Enhancement in Difficult Environment
Original language description
The topic of the paper is to describe influences of the difficult environment to the GNSS and SBAS signals and consequences for signal processing. The satellite line of sight shadowing influence to signal reception is discussed for various environments together with proposed shadowing model. The model is derived from two state Markov model. The experimental measurements of mobile reception of EGNOS signal has shown the need of supporting SBAS signals in several environment by complementary transmission.Such concept of supporting system with data transmitted by separate channel is discussed in the paper both for DGNSS and SBAS case. The possibility and analysis of use of Internet for real time distribution of augmentation data is presented in the paper, namely questions of data latency and augmentation influence to user position in difficult environment.
