Okean Projects & MONSID Applications

MONSID has been extensively tested, verified, and validated, including performance analysis. More importantly, MONSID has been actively used over a wide variety of actual systems.

JPL Athena Test Rover

MONSID uncovered surprise behaviors, unanticipated interactions between controller and planner, real faults, terrain-induced stalls, motor stalls, hidden/masked faults that would have fooled a traditional monitor.

Here’s a video the CAST team posted of a recent demo where MONSID was utilized to help them determine when a problem was encountered. MONSID software is showcased in the top 2 charts. For this demo, the satellite was supposed to adjust orientation around the asteroid (the spud-looking thing on the wall) using its reaction wheels. About 20 seconds into the demo, one of the wheels failed. MONSID detected the failure (the blue line spikes in the top chart) and the information was used by the planner (provided by JPL) to effectively update the plans (and hence switch to other controlling hardware) to allow completion of the originally desired task.

NASA SBIR Phase I 2020 Project: Model-based Fault Diagnosis for Autonomous Propellant Management

March 1, 2021

This was a 6-month SBIR Phase I project with Kennedy Space Center that included early technical development to determine the feasibility of the innovation.

The topic covers Autonomous Operations Technologies (AOT) that support activities performed by rocket engine test facilities, propellant servicing systems, processing and launch of vehicles and payloads, and for extended surface operations on the Moon and Mars. AOT performs functions such as systems and components’ fault prediction and diagnostics, anomaly detection, fault detection and isolation, and enables various levels of autonomous control and recovery from faults, where recovery may include system repair and/or reconfiguration. 

We proposed our MONSID technology in support of Autonomous Propellant Management (APM). MONSID supports autonomous operations technology requirements to reduce operations and maintenance costs and minimizes human in the loop intervention. Applied to propellant management and test facilities, the MONSID technology can provide a critical component for autonomous health management of these systems.
