Abstract

When developing temperature control interface modules used as part of spacecraft onboard equipment, it is important to correctly substantiate the set of measures to ensure their noise immunity, taken at the design levels of the measuring system, measuring device and temperature control interface module. Such a justification involves an assessment of the effectiveness of possible interference mitigation techniques at each design level. The article is devoted to the consideration of interference mitigation measures at the design level of the measuring device, which should be taken to ensure the required noise immunity of the temperature control interface module in combination with measures taken at other design levels. It is shown that in order to ensure the required noise immunity of temperature control interface modules, it is necessary at the design level of the measuring device to provide for measures to mitigate interference in the power supply module, the central instrument module and inter-module interfaces, as well as measures to eliminate gross measurement errors (misses) when processing digital data in the central instrument module. In the power supply module, it is possible to attenuate interference by introducing differential and common mode filters at the input and switching filters at the output. In the central instrument module and inter-module interfaces of the secondary power buses, noise mitigation is possible by dividing the common power bus into analog and digital buses and combining them at an equipotential point. In the central instrument module, it is possible to eliminate misses by using various statistical methods for processing digital data.
