The unit comprises four ceramic vibrating structure gyroscopes and four QLC 400 accelerometers configured on a truncated tetrahedron design. This design allows for the optimal configuration of the eight sensors, which in turn provides for a theoretical 33% increase in information. The redundant sensor configuration also allows for fault detection, which is required for many autonomous applications. This initiative is a precursor for future developments with more sensors to provide fault isolation. The paper will also present a navigation system implementing the redundant IMU with the global positioning system. Results are provided of this navigation system being implemented in an unmanned air vehicle.<\/jats:p>","DOI":"10.1177\/02783640022067995","type":"journal-article","created":{"date-parts":[[2003,7,19]],"date-time":"2003-07-19T02:59:46Z","timestamp":1058583586000},"page":"1089-1103","source":"Crossref","is-referenced-by-count":65,"title":["A Low-Cost, Redundant Inertial Measurement Unit for Unmanned Air Vehicles"],"prefix":"10.1177","volume":"19","author":[{"given":"Salah","family":"Sukkarieh","sequence":"first","affiliation":[{"name":"Australian Centre for Field Robotics, Department of Mechanical and                         Mechatronic Engineering, University of Sydney, NSW 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Gibbens","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ben","family":"Grocholsky","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keith","family":"Willis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hugh F.","family":"Durrant-Whyte","sequence":"additional","affiliation":[{"name":"Australian Centre for Field Robotics, Department of Mechanical and                         Mechatronic Engineering, University of Sydney, NSW 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2000,11,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"crossref","unstructured":"Dissanayake, G., Sukkarieh, S., Nebot, E., and Durrant-Whyte, H. 1999.
