Software designs for enhanced maritime service options

Abstract

Herein, we focus on the design of software RSIM for enhanced maritime DGNSS operation and its service. First, it describes the architecture of RS and 1M systems, and analyzes the performance requirements of the RTCM SC-I04 document. In order to achieve this study, we proposed the design of the software for the DGNSS RSIM architecture, operational module for the control and monitoring of GNSS receivers, module for generating the differential corrections and converting to RTCM format, and it then broadcasts the differential corrections to user receivers using the MSK modulator. For the performance requirements of the proposed software RSIM, the pseudorange (PR) measurement, the pseudorange corrections (PRCs) and position accuracy are presented in the Interests of performance analysis of the software RSIM. We then analyze the functionality of maritime DGNSS integrity monitoring and the key components for generations of 1M information. In addition, we present the performance analysis results of the proposed software DGNSS RSIM. Finally, our conclusions are presented. ？ 2011 IEEE.
