Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This paper presents the authors' ongoing work on designing a novel 3-axis solar tracker platform utilizing a 3-DOF spherical parallel manipulator with revolute joints and a solar sensor. The selected solar sensor and the SPM configuration are described in details. A novel approach is proposed for the SPM platform orientation estimation based on solar sensor measurements employing trigonometric identities and quaternion rotation representation. The proposed approach is experimentally verified using a SPM 3D-printed prototype equipped with a solar and an orientation sensors. It is assumed that the proposed concept for a novel 3-axis solar tracker platform can further applied to design novel mobile solar tracking systems.
