Data from the onboard health monitoring sensors needs to be accommodated within a small fraction of this downlink bandwidth. The problem is more acute for interplanetary missions, where the downlink data rate is significantly lower than the low earth orbit missions. Such constraint prohibits transmission of the complete set of health monitoring data. This proposed Phase-II effort is geared towards providing enhanced remote diagnostics using limited telemetry bandwidth. Diagnostic accuracy of health management system depends more on the information content of the monitored data, than on its sheer volume. We propose accommodating more information within the allocated downlink bandwidth for health monitoring by performing intelligent data reduction. The onboard data reduction process employs sensor fusion, dimensionality reduction and temporal fusion techniques.

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.
