Such conditions as a thruster failure moments before an automated docking, or imprecise or unknown inertial properties due to fuel slosh, partially deployed appendages, etc., can cause controllers to become unstable or otherwise unable to complete their objectives. Based on our prior work in control systems and specifically in developing the existing Synchronized Position Hold, Engage, & Reorient Experimental Satellites (SPHERES) ISS testbed, we propose to analytically characterize the requirements to implement algorithms for autonomous thruster fault identification, fuel slosh and online inertia property estimation on the SPHERES system. This Phase I effort will focus on the necessary software architecture changes and any hardware modifications required to implement these algorithms using SPHERES. Successful completion of this effort will produce specifications and preliminary designs for all necessary components, and pending a manifest opportunity, lead to testing the new algorithms in ISS within Phase II. This proposal offers valuable innovation in three respects: creation of novel spacecraft control algorithms, rapid advancement from concept to spaceflight demonstration, and low-cost/high-return use of existing spaceflight resources.","startYear":2004,"startMonth":1,"endYear":2005,"endMonth":1,"statusDescription":"Completed","principalInvestigators":[{"contactId":208061,"canUserEdit":false,"firstName":"Javier","lastName":"deluis","fullName":"Javier Deluis","fullNameInverted":"Deluis, Javier","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
