Description:
The objectives of the Nimbus-G mission are to study air pollution, ocean parameters, and weather and climate on a global scale. The observations required to meet these objectives include nadir viewing and scanning, and limb viewing and scaling techniques. Each of these approaches requires that the spacecraft provide a sensor mounting surface that maintains a fixed orientation relative to the nadir and the orbit track and that the orientation of the orbit plane remain constant with respect to the sun for maximum space cooler efficiency. The tradeoffs necessary to satisfy the conflicting instrument payload requirements within the constraints placed on the Nimbus design are discussed, along with the modifications necessary to meet the unique needs of the instrument complement.
