Phase A Technical Study Summary Report for a Tropical Earth Resources Satellite (TERS)

摘要

The high (1681 km) equatorial orbit of the Tropical Earth Resources Satellite with its particle radiation hazards (as compared to an alternative low near equatorial orbit with operational complications) was studied. Selective viewing by cloud sensor and cross track instrument pointing was analyzed. The consequences of the high spectral resolution (20 m color, 10 m panchromatic) for the designs of instrument, satellite systems, data handling, and ground data processing were assessed. Ground observations at different solar illumination angles and view angles were simulated. A satellite configuration concept was defined. The concept seems feasible, although it is technologically challenging. Radiation aspects require a careful development and may influence the design of instrument and spacecraft systems.
