Design Of An Electrical Power System For The Openorbiter Cubesat, Sofiane Chaieb, Michael Wegerson, Jeremy Straub, Ronald Marsh, David Whalen

Jeremy Straub

The OpenOrbiter Small Spacecraft Development Initiative aims to create an Open Prototype for Educational Nanosats (OPEN) framework (see [1]) for a complete 1-U CubeSat (10 cm x 10 cm x 10 cm, 1.33 kg spacecraft) with a total parts cost of less than $5,000 [2]. In order to supply all spacecraft subsystems with power, an electrical power system (EPS) has been implemented. The EPS generates power using multiple solar panels, stores it in batteries and regulates it to provide continuous levels of power to all of the subsystems of the spacecraft. The EPS has a crucial role in the spacecraft …

Scada System Security: Accounting For Operator Error And Malicious Intent, Ryan Kilbride, Jeremy Straub, Eunjin Kim

Jeremy Straub

Supervisory control and data acquisition (SCADA) systems are becoming more and more com-monplace in many industries today. Industries are making better use of software and large scale control systems to run efficiently, without the need for large amounts of oversight. Security is a particularly large issue with such systems, however. A human must still be involved to ensure smooth operation in the event of catastrophic system error, or unusual circumstanc-es. Human involvement presents problems: operators could make mistakes, configure the system to operate sub-optimally or take malicious actions. This imple-mentation of SCADA security aims to combat these problems.

A 6-U Commercial Constellation For Space Solar Power Supply To Other Spacecraft, Corey Bergsrud, Jeremy Straub

Jeremy Straub

This poster presents early stage planning for a constellation

of 6-U CubeSats which will collect power from

the sun and supply it to other spacecraft in Earth orbit. Unlike

solar panels (which have a known decay rate), antenna

systems (such as would be required to receive microwavetransmitted

power) do not substantially decay over the

typical (or prospectively extended, under this model)

spacecraft lifetime. This allows a spacecraft to be built for

long-term operations (utilizing an electric propulsion technology

and/or a greater supply of conventional propellant)

and receive power from a lower-cost utility provider

spacecraft, which can be replaced on a …
