The technique of selecting a guard band in the climatic tests of radio-electronic equipment

The purpose of this study is to create a methodology for assessing the risks arising from climatic tests of radio-electronic equipment. The article considers the effect of additional misalignment of transmission lines arising under conditions of temperature inhomogeneities on the increase in consumer and producer risks. A method of selecting a protective measuring band is proposed to minimize the probability of false acceptance and rejection of the tested devices. The results obtained make it possible to determine the optimal, from the point of view of the risks of the consumer and the manufacturer, the coefficient of the protective band of radio engineering measurement.

Application of Unmanned Aerial Vehicle Remote Sensing in Engineering Measurement

<p>Unmanned aerial vehicle remote sensing is widely used in the whole engineering measurement in recent years. It has many advantages including simple operation, high accuracy and high efficiency. It is precisely because of these advantages that unmanned aerial vehicle remote sensing has gradually replaced the traditional surveying and mapping technology to be widely used. With the continuous expansion of the number and scale of projects in China, the effect of unmanned aerial vehicle remote sensing in engineering measurement is getting bigger and bigger. This article mainly analyzes the advantages of unmanned aerial vehicle remote sensing and its application in engineering measurement, so as to provide some reference for the development of surveying and mapping engineering in China.</p>
