In consideration of the site selection of a satellite ground receiving station, a set of rules of allowable electromagnetic interference (EMI) levels is proposed in this paper. The methods for analysing calculating and measuring EMI are described, and the requirements which the measuring system should fulfil are also suggested. Moreover, as far as some kinds of spectrographs and common EMI sources are concerned, the data-processing methods are mentioned in detail. These considerations can also be consulted by...
