GPS-based auxiliary navigational instruments

In case of light aircrafts, in uncontrolled airspace the navigation and the air traffic monitoring is the responsibility of the pilot. Navigation and driving of the airplane simultaneously amongst complicated meteorological conditions means intensified load from the viewpoint of the pilot, even with the continuous support of the flight information service. Recently several applications are developed to support navigation tasks. Despite their obvious utility, according to our experiences, they are usually solving only some specific problems. Therefore, improvement of auxiliary navigational applications and their services is still actual and important topic. In our paper several algorithms and applications are presented to emulate classic IFR (Instruments Flight Rules) instruments on the basis of the commercially available GPS (Global Positioning System) service, which were developed on different platforms at the Institute of Instrumentation and Automation [1] [2] [3].
