    Implementation of Geostar's RDSS system (1990)
    In:  CASI
    Details
    Publication Date: 2013-08-31
    Description: The Geostar (Trademark) system began its initial operations in 1988 and was the first domestic satellite system to provide regular service to mobile users within the United States. Here, an overview is given of Geostar's radiodetermination satellite system (RDSS) concept and its development by Geostar, with a focus on the current operational status of Geostar's interim RDSS system and services.

    Licensing of future mobile satellite systems (1990)
    In:  CASI
    Details
    Publication Date: 2013-08-31
    Description: The regulatory process for licensing mobile satellite systems is complex and can require many years to complete. This process involves frequency allocations, national licensing, and frequency coordination. The regulatory process that resulted in the establishment of the radiodetermination satellite service (RDSS) between 1983 and 1987 is described. In contrast, each of these steps in the licensing of the mobile satellite service (MSS) is taking a significantly longer period of time to complete.
