- Abstract
- This paper presents the considerations on NCR (Network Clock Reference) variations which impact on the stability of the satellite interactive system operation. We identified what kinds of factors can influence system performance in timing synchronization aspects. The amount of impacts that each factors can cause to the system operations from the realistic calculations and corresponding solutions are presented. These calculations may not be exact in real satellite transmission situation. However, we are sure that this can be good guidelines for system design. Besides processing delay and several measurement algorithms accuracy which are typically system specific, the impacts from user access position, satellite movements and user movements are addressed as the most common factors which every satellite system can experience. It is turned out that user access point causes the most critical impact on network synchronization from the analysis. These factors should be considered in any types of mobile and fixed satellite systems using TDMA (Time Division Multiple Access) scheme.
