APPLICATION OF G MODEL TECHNOLOGY IN AVIONIC SYSTEMS

G MODELS ARE A METHOD FOR REPRESENTING THE ELEVATION OF THE EARTH'S SURFACE THAT PROVIDE SOME SIGNIFICANT ADVANTAGES OVER THE CONVENTIONAL MATRIX FORM USED IN DIGITAL TERRAIN ELEVATION DATA (DTED). AVIONIC SYSTEMS CURRENTLY UNDER R&D IN PROGRAMS SUCH AS ITARS IN THE AVIONICS LABORATORY MAKE EXTENSIVE USE OF DTED. ONE OF THE PRIMARY BENEFITS FROM USING G MODELS IN AVIONIC APPLICATIONS IN PLACE OF DTED IS THE FACT THAT THEY MAY USE LESS THAN 10% OF THE STORAGE SPACE REQUIRED BY DTED. SINCE THE G MODELS CONTAIN PROCESSED INFORMATION EXTRACTED FROM THE RAW DTED, THEY CAN IMPROVE THE PERFORMANCE OF CERTAIN FUNCTIONS AND REDUCE THE AMOUNT OF COMPUTATION REQUIRED. THIS PROPOSAL IS FOR A STUDY THAT WILL BETTER QUANTIFY THE POTENTIAL BENEFITS AND DEMONSTRATE THE UTILIZATION OF G MODELS IN SELECTED AVIONICS APPLICATIONS.
