Recently, one of the classes of electromagnetic interference has become particularly topical: the effect of radiated interference on the equipment (in the form of an alternating electric field) and the emission of radiated noise from the equipment. The reasons for this are as follows:
1. An increase in the capacity of spacecraft leads to an expansion of the quantitative composition of radio transmitters of spacecraft. The number of channels of transmitting equipment is increasing, their power, multi-range, and, consequently, the number of transmitting antennas in the spacecraft is significantly increased.
2. The evolution of equipment aimed at optimizing its mass and size and functional characteristics can lead to an increase in its sus-ceptibility to external fields.
3. Increasing the functional load and speed of equipment leads to an increase in the level of radiated interference, which may affect the receivers and other equipment.
4. Transition from the hermetic design of the equipment bay to an unsealed.
In this article, some methods realized in JSC «ISS» for calculating the electric field strength in the spacecraft structure are considered:
analytical, modeling and experimental methods for calculating the radiation of the transmitting antennas of spacecraft on the equipment outside the equipment bay of the spacecraft;
analytical and experimental methods for calculating the radiation of equipment to the spacecraft receivers through receiving antennas;
methodology for calculating the radiation of the transmitting antennas of spacecraft on the equipment inside the equipment bay of the spacecraft;
a technique for calculating the radiation of equipment to another equipment inside the equipment bay.
The developed methods have been tested in the process of creating and conducting ground-based experimental testing of all non-hermetic spacecraft developed by JSC «ISS». It should be noted that after the introduction of the methodology developed above to provide EMC spacecraft with respect to radiated interference, the cases of abnormal operation of the equipment as a result of the de-terioration of the electromagnetic environment of the spacecraft in the process of ground tests and in the course of field operation were not recorded.
