Power demands of communication technologies between LEO small-satellites are difficult to counterbalance by solar infeed and on-board battery storage, due size weight limitations. This makes the problem battery-powered inter-satellite a very one. Its management requires profound understanding as well techniques for proper extrapolation electric power budget part satellite-to-ground design. We discuss how construction contact plans in delay tolerant networking can profit from sophisticated...
The kinetic battery model is a popular of the dynamic behaviour conventional battery, useful to predict or optimize time until depletion. however lacks certain obvious aspects batteries in-the-wild, especially with respect to the effects random influences and when charging up capacity limits. This paper considers limited capacity in context piecewise constant yet charging and discharging. We provide exact representations battery behaviour wherever possible, otherwise develop...
Summary Size and weight limitations of low‐Earth orbit (LEO) small satellites make their operation rest on a fine balance between solar power infeed demands supporting communication technologies, buffered by on‐board battery storage. As result, the problem planning battery‐powered intersatellite is very difficult one. Nevertheless, there growing trend toward constellations mega‐constellations that are to be managed using sophisticated software support. In earlier work, we have discussed how...

The kinetic battery model is a popular of the dynamic behavior conventional battery, useful to predict or optimize time until depletion. however lacks certain obvious aspects batteries in-the-wild, especially with respect (i) effects random influences and (ii) when charging up capacity bounds. This paper considers bounded in context piecewise constant yet discharging. resulting enables time-dependent evaluation risk exemplified power dependability study nano satellite mission.
