Abstract
A head-tracking system includes a georeferenced head tracker (GHT) configured to provide georeferenced head position data, and a platform-referenced head-tracker (PRHT) configured to provide platform-referenced head position data. A controller is coupled with the GHT and the PRHT, and configured to be coupled with an avionic system configured to provide georeferenced aircraft position data. The controller includes a processor configured to access the georeferenced head position data, compare a current drift error of the GHT with a predetermined error threshold. When the current drift error is below the threshold, the processor transmits a signal indicative of the georeferenced head position data being a current georeferenced head position data. When the current drift exceeds the threshold, the processor access the georeferenced aircraft position-data, generates update data based on the platform-referenced head position data and the georeferenced aircraft position data, and updates the GHT at a known instant in time.
