“…In the case of 1U cube satellite which dimension is only 10cm×10cm×10cm the area of receiving the sun light is very narrow, therefore the output power is much small to use. That's why it is very important to develop a better power sub system for cube satellite and cost efficient power unit which gives much better output and efficiency [1] [2]. The specific power system deals with all the requirements and specification of cube satellite components.…”

Satellite industry almost completely dependent on centralized Electrical Power System (EPS) designs. Maximum EPS is custom designed. There are a few manufactures that make their designs available for commercial use. Most of these designs conform to the most common standard that uses three distributed buses. Today large satellite follows single bus voltage distributed architecture. Therefore single bus voltage distributed architecture is now become a mainstream architecture for small cube satellite. Power system unit has distributed voltage which is more than one, such as a low voltage bus and a high voltage bus. There is generally one bus voltage within a subsystem. Every subsystem module is accountable for additional regulation or point-of-load regulation. With the developments of small, very efficient, monolithic dc-dc converters, this paper shows the design and simulation of possible implementation of distributed architecture at the cube satellite scale. The goal of this paper is to design an efficient electrical power system (EPS) with a great utility, capable of being used for several missions, without having to redesign the system every time. KeywordsPower system of cube satellite, small satellite power system, power system model, satellite power system.

Both WSNs (Wireless Sensor Networks) and observation satellites are able to get measurements from a geographic area. To interconnect these technologies, we propose to use a store-carry-and-forward architecture relying on the DTN (Disruption and Delay Tolerant Networking) Bundle Protocol. This architecture aims at being generic, so it is application-agnostic and suits a wide range of scenarios. WSN may collect sporadically large data volume while terrestrial stations communicating with Low Earth Orbit (LEO) satellites have to endure long link disruptions when the satellite is not in the line of sight. These sporadic growths within the WSN coupled with the large latency on satellite links require to schedule data to provide quality of service to several flows. We propose a scheduling policy based on deadline of Bundles and compare it with classical DTN solutions.
