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.

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).

MONSID was initially developed under a 2015 NASA Phase I project and a 2016 NASA Phase II SBIR project. In support of MONSID model design and analysis we created a host of tools including MONSID Toolkit, which was developed under a 2018 NASA Phase 2x project.

About the Founders

Ksenia Kolcio
President, Okean Solutions, Inc.

Ksenia Kolcio is the President and co-founder of Okean Solutions, Inc., where she leads the aerospace systems business activities. She has been PI and supported several Phase I, II, III, and BAA programs for NASA and AFRL.

Focus areas include spacecraft fault management and GN&C technologies and analysis tools. Ksenia has successfully proposed, negotiated and executed Phase I, II, and III contracts with the AFRL and NASA to develop fault management for responsive spacecraft. She also collaborated with other small businesses on NASA Phase II/III programs to develop x-ray based navigation technologies (XNAV) and user interface and measurement models for navigation mission prototyping tools (GSFC ODTBX).

Prior to forming Okean Solutions, Ksenia was employed at Microcosm, Inc. as a Senior Systems/GN&C Engineer. There she provided algorithm development, simulation/analysis, SBIR program technical lead/management, as well as hardware and software development support. Projects included miniaturized three-axis attitude and navigation sensor solutions, Lunar gravity sensor concept, control simulation for free-floating space telescope mirrors.

Ksenia started her career at Northrop Grumman Space Technology (NGST) in the Avionics Systems Center. She was the lead autonomy and fault management engineer for two classified programs responsible for the FM architecture design and requirements flow down and traceability. On the NPOES program she developed flight vehicle simulator architecture for operator training and procedure checkout. She was also testbed lead engineer on the AEHF Gimbal Control Subsystem responsible for the design, build-up, integration of the testbed simulator and test harness, resulting in successful on-time verification. At the beginning of her career at NGST, Ksenia was a control system engineer for internal research and development projects, such as the optical intersatellite link program and the autonomous onboard processing initiative where she worked on applying a model-based FM system to spacecraft GN&C systems.
