ADDASAT Development Plan for the Attitude Control System

Abstract

As a part of the ORVEAL project, a real scale laboratory model of the inertial platform for ADDASAT is developed by the joint ADDA and UPB teams, ensuring the capability of a three-axis attitude control demonstration in the ground laboratory that simulates weightlessness by low friction bearings. The study is part of the larger ADDA-UPB program for developing the low cost NERVA orbital system for applications in enhanced environmental policies and land resources surveillance. The ORVEAL research is granted by Romanian UEFISCDI financing authority.

Feasibility of the Microcomputers for the ADDASAT Capsule

“…The state equations come from algebraic expressions containing parameterized cosines, sums and products [9]. The inputs are passed through a wash-out filter, while for the feedback loop we use a Kalman filter in lieu of the standard Luenberger state estimator, both solutions commonly applied in practice.…”
