Real-time fault detection and identification for increased autonomy

MONSID® is a premiere model-based fault detection and isolation software package that provides a clear, continuous confirmation of health status under nominal and anomalous conditions. MONSID’s unmatched capability makes it easy to use across different project phases from system development to hardware integration to real-time, on-board analysis.

MONSID makes it easy to confirm your system is Healthy.
And, if it’s not, MONSID will tell you what has failed!

Smarter Health Assessment tames complexity

MONSID models need to describe nominal behavior only - the model captures operational intent. It is faster and easier to model correct behavior rather than building and maintaining elusive and time-consuming fault models.

Traditional fault models are not necessary!

MONSID's Smarter Health Assessment tames complexity

Rover modeling only correct behavior is faster and easier.

Count on MONSID for clear and concise results in all phases of your project

Let MONSID serve as the foundation of your fault management system to uncover both unexpected and unintended behaviors - from Integration and Test to real time, on-board use to offline analysis.

Use MONSID in all phases of your project

MONSID can help uncover both unexpected and unintended behaviors. You can effectively use the same model from day 1 of your project to help test your system as well as serve as the foundation of your fault management system.

From Integration and Test to real time, on-board use to offline analysis, MONSID gives you clear concise results in all phases of your project.

Compliment your existing fault response and recovery systems

MONSID can be paired with other on-board or remote systems that are responsible for fault response and recovery. We have integrated MONSID into many open-source and custom frameworks, allowing our customers to add to or improve their system’s responsiveness to anomalies.

These frameworks include some of the most common currently in service: NASA’s core Flight Software (cFS), the Robot Operating System (ROS), and NASA’s F’ (F Prime).
