This report deals with providing tracking to an outdoor mobile augmented reality system and the Zion Augmented Reality Application. ZionARA is meant to display a virtual recreation of a 13th century castle on the site it once stood through an augmented reality Head Mounted Display. Mobile outdoor augmented/mixed reality puts special demands on what kind of equipment is practical. After briefly evaluating the different existing tracking methods, a solution based on GPS and an augmented inertial rotation tracker is further evaluated by trying them out in a real setting. While standard unaugmented GNSS trackers are unable to provide the level of accuracy necessary, a differential GPS receiver is found to be capable of delivering good enough coordinates. The final result is a new version of ZionARA that actually allows a person to walk around at the site of the castle and see the castle as it most likely once stood. Source code and data files for ZionARA are provided on a supplemental disc.
