Abstract

This paper presents the design of high altitude balloon experiment (HABE) attitude determination and control architecture. Inertial pointing forms the foundation of the HABE tracking system where the precise attitude control system is required to ensure target acquisition. The basic concept involves constructing an inertial line of sight (LOS) vector with target and HABE trajectory measurements and controlling the gimbal attitude to create a parallel LOS. Algorithms are developed incorporating the gimbal dynamics and inertial sensor information to optimize the pointing control system's flexibility and accuracy. Coordinate transformations between inertial, sensor, and vehicle frames intensify the complexities in realizing the pointing control system design. Kalman filtering is incorporated, providing trajectory prediction and compensating measurements for extraneous noise and latencies. The complete architecture of the pointing control system is analyzed with both frequency domain models and time domain simulation to characterize performance predictions.
