The Multi-Tier Mission Architecture And A Different Approach To Entry, Descent And Landing, Jeremy Straub

Jeremy Straub

Planetary missions are generally very well planned out. Where the spacecraft will be deployed, what it will do there and in what order are generally determined before launch. While some allowance is made for greater depth exploration of scientifically interesting items identified during the investigation, a successful mission is (generally) one that doesn’t deviate significantly from its planning. When sending an initial mission to an unsurveyed planet or moon, however, this approach is not suitable. Current space technology provides the capability to send a combined survey and lander mission (instead of conducting an initial survey mission and following it up …

Enabling Interplanetary Small Spacecraft Science Missions With Model Based Data Analysis, Jeremy Straub

Jeremy Straub

Small spacecraft operating outside of Earth orbit are significantly constrained by the communica- tions link available to them. This is particularly true for stand-alone craft that must rely on their own antenna and transmission systems (for which gain and available power generation are limited by form factor); it is also applicable to ‘hitchhiker’-style missions which may be able to utilize (quite likely very limited amounts of) time on the primary spacecraft’s communications equip- ment for long-haul transmission.

This poster presents the adaptation of the Model-Based Transmission Reduction (MBTR) frame- work’s Model-Based Data Analysis (MBDA) component for use on an interplanetary …

An Expert System For Spacecraft Design, Jeremy Straub, Christoffer Korvald, Tyler Hill, Joshua Berk

Jeremy Straub

Designing a spacecraft is a complicated process that can be problem-prone. This is particularly true in the case of a small spacecraft where volume and mass limitations are enforced by form factor requirements. The Open Prototype for Educational NanoSats implements several restrictions beyond those from the CubeSat form factor, including two different board size specifications which impact the configuration of the payload area support structure and the size of available batteries.

OpenEdge aims to avoid the discovery of form factor, OPEN-specific and other configuration issues during final assembly by checking prospective configurations against the applicable requirements and constraints set during …

A Human Proximity Operations System Test Case Validation Approach, Justin Huber, Jeremy Straub

Jeremy Straub

A Human Proximity Operations System (HPOS) poses numerous risks in a real world environment. These risks range from mundane tasks such as avoiding walls and fixed obstacles to the critical need to keep people and processes safe in the context of the HPOS’s situation-specific decision making. Validating the performance of an HPOS, which must operate in a real-world environment, is an ill posed problem due to the complexity that is introduced by erratic (non-computer) actors. In order to prove the HPOS’s usefulness, test cases must be generated to simulate possible actions of these actors, so the HPOS can be shown …
