Payloads sensitive magnetic fields require low magnetic field emission levels from other payload instruments or platform equipment, or at least the characterization of them. Payloads can be sensitive to constant ("DC") or time-varying ("AC") magnetic fields itself, both periodic and aperiodic, or especially to the spatial field gradients, i.e.

Small satellites have seen a significant growth over the past decade and have emerged as a viable complement to traditional large satellite solutions for many applications. This growth is mainly justified by their short development time and low cost.

With the current best knowledge, equipment such as Star-Trackers, RIUs, PCDUs, Batteries are elements of great uncertainty and for which the demise models need to be matured and validated. In some of these cases this may be related to lack of knowledge and validated models by test leading to conservative assumptions on materials used, modelling approach and break-up process these are units that may not demise in system level simulations (unlike what was indicated in previous studies).

Background and justification:

The project focused on the development of technology for wireless energy transmission from a fixed station to a vehicle. A rover-like vehicle on the surface of the moon was assumed for the definition of the system parameters. Previous studies and projects for SPS WPT systems focused on the frequency ranges at 2.4GHz or 5.8GHz and less in the mm-wave range when selecting the transmission frequency. The reason for this is the lower attenuation of the transmission through the atmosphere.
