Communication performance simulation for the Asia Cellular Satellite System

Mobile satellite systems (MSS) are offering a solution to increased demand for cellular communications in developing areas of the world. The Asia Cellular Satellite System (ACeS) is a regional MSS being developed by Lockheed Martin Corporation (LMC) to provide such communication to Asia. Based on one geostationary satellite, the ACeS System has a variety of communication services for which System Engineering and Test (SE&T) at LMC's Management & Data Systems (M&DS) Division is responsible for ensuring adequate performance. These services carry such information as speech signals, data signals, and control signals. This paper describes the methodology and the communication simulation tools which SE&T engineers have developed and are using to ensure adequate performance.
