| Popis: | Applications of aircraft attitude information obtained from single-antenna global positioning system (GPS) receiver measurements are discussed. A recently introduced framework to synthesize attitude information from GPS velocity vector measurements is reviewed. The framework combines the benee ts of high-quality GPS velocity measurementswithanovelvelocity-vector-basede ightcontrolparadigmtoprovideameansforthehumanoperator orautopilottoclosetheaircrafte ightcontrolloop.Threepossibleapplicationsofthisnovelconceptarediscussed.A single-antenna GPS-based backup attitude indicator is evaluated in e ight and compared to thetraditional attitude indicator. In addition, single-antenna GPS-based autopilot and tunnel-in-the-sky trajectory guidance systems are demonstrated in e ight. Unlike traditional attitude indicators and autopilot and trajectory guidance systems, these applications rely solely on the information obtained from a single-antenna GPS receiver. This concept thus has signie cant system integration and cost advantages and makes a number of glass-cockpit capabilities affordable to the General Aviation aircraft community. |
