Description
technical field [0001] The invention relates to the technical field of DME ground navigation, in particular to a monitoring system of precision DME ground navigation equipment. Background technique [0002] In recent years, with the increasing number of navigation equipment in airports at home and abroad, the requirements for equipment are also getting higher and higher. At present, the design method of the monitoring system of DME / P equipment is outdated. It is built for decades of integrated circuits, and there is no localization, so it is difficult to debug. In addition, the functions are very limited, the speed response is slow, the lack of protection design, and it is easy to be interfered. Now there is an urgent need for localization and more optimized functions. A new monitoring system with good self-test capabilities and special test capabilities appears. In addition, it also needs to have requirements such as technological advancement, work stability, and performanc...
