An experimental geostationary platform - A step toward the 1990's

NASA studies on geostationary platforms are reviewed. Traffic models for geostationary missions through the year 2000 are presented, and the benefits of platforms are shown, as compared with accomplishing the same missions on specialized satellites. These benefits are illustrated by a case study (involving Leasat) demonstrating that substantial cost savings can result because of economies of scale. Technologies in need of development and demonstration are identified, and attention is given to the potential NASA Experimental Geostationary Platform.

Design concept of geostationary platform

The payload efficiency of communication satellites has typically averaged 25 to 30% while meteorology and earth observation satellites range from 30 to 35%. Improvement in solar cell efficiency, batteries, electric propulsion for stationkeeping, and solid-state circuitry will increase this efficiency in the future, but it will still be advantageous in the Shuttle era to reduce the expenditure for support systems. A platform that provides all the support functions could reduce the initial cost due to economics of scale and also reduce transportation cost. Three alternate configurations of a platform for geosynchronous orbit communications and meteorology missions are presented

MSFC presentation charts on geostationary platform

A concept is presented of a geostationary platform. The concept takes the form of antennas and other payloads mounted on a strongback structure. The utilization and benefits of the platform are discussed.
