BEHAVIOR OF THE INFORMATION PARAMETER OF THE GLIDE PATH BEACON OF THE LANDING SYSTEM IN A WIDE SECTOR OF ANGLES
The article is devoted to the problem of information protection generated by a glide path beacon of the PRMG format for providing instrumental approach of aircraft for landing. To en-sure a safe approach, the radio beacon landing system forms a descent trajectory in space - a glide path. A developed multilevel control system is designed to ensure the integrity of the land-ing system by continuous monitoring of the position of a given glide path and the steepness of the indicated glide path parameter. However, during flight tests of a glide path beacon (GPB), a false glide path is sometimes detected in the area of the landing system, which naturally vio-lates its integrity. The article shows the reason for this phenomenon - a violation of the multi-plicity of the heights of the suspension of the radiating elements of the GPB antenna array. Flight measurements data of the glide path zone at the airfield in the foothills are given. The experimental results confirm the theoretically found regularities in the behavior of the informa-tion parameter of the glide path beacon in a wide sector of angles. Recommendations are pro-posed for maintaining the integrity of the landing system
