Abstract

The manuscript describes the design drivers and performance of a high efficiency quasi-real time satellite mobile messaging system well adapted to the location-based and data acquisition services targeting in particular the automotive market. It is shown that the proposed solution is providing a random access channel throughput around 2 bit/s/Hz with reliable packet delivery over satellite mobile channels. This very high throughput is obtained by a relatively simple packet transmission control based on downlink signal quality observation and an optimized design of spread Aloha with successive interference cancelation (SIC) at the gateway.
