POPSAT: A candidate satellite system for solid Earth applications and sciences. Preliminary feasibility study. Volume 1: Summary
Abstract
A solid-Earth satellite system performance analyses, and related tasks such as microwave tracking system definition and error assessments, gravitational and nongravitational disturbance forces and their modeling accuracies are summarized. System performance simulations demonstrate that mission requirements can be fulfilled. The most cost effective launch would be a shared launch into sun-synchronous orbit and injection with a bipropellant stage into the final orbit of 7000 km altitude. This design baseline with more stringent mass constraints led to a low mass design. The minimum achievable satellite mass of POPSAT is 550 kg. A data management concept was tailored to the POPSAT system, and a satellite design compatible with the low mass constraint was conceived. Accommodation of a LASSO derived Time Synchronization Experiment was investigated and is found to need thorough review of the mission objectives and scenario. A development program was set up and all elements related to the POPSAT system were identified and costed.
