Portfolio > Training Simulations

Simulations are a vital part of training in several industries and are essential for human spaceflight missions. The examples below demonstrate METECS’s ability to leverage our core products and services to enhance NASA's training simulations.

TS21 Demonstrations

METECS is currently providing significant contributions to the architecture, modeling and simulation, and integration of NASA's Training Systems for the 21st Century (TS21). Recently, METECS supported three major demonstrations of improved TS21 simulation capabilities.

Cupola Mock-Up Demonstration

The “Cupola Mock-Up” Demonstration presented the initial integration of the TS21 ISS, CTNS, and Generic Visiting Vehicle simulations with User Support Services and Graphics in the TS21 Integration Rig. While put together on very short notice, it showcased significant milestones including simulating a 30 meter approach of the Japanese HTV vehicle to the ISS using 3 simulations interfaced through HLA. It also demonstrated the SSRMS performing a scripted OCAS maneuver. Specific METECS contributions included 3D graphics integration, as well as interfacing the vehicle dynamics via HLA. The METECS software package mRest was used to start the simulations and provide simulation health and status monitoring.

METECS's contributions to this effort, along with our rich history of simulation integration, has equipped us with an understanding of the intricacies of interfacing external visiting vehicle simulations to the simulated ISS through HLA. This skill has applicability to NASA, as well as commercial space companies needing to interface their vehicle simulations with NASA’s ISS simulation.

Robotics Capture/Berth Cupola Demonstration

The follow-on “Robotics Capture/Berth Cupola” Demonstration presented a human-in-the-loop (HIL) capture and install of the Japanese HTV to the ISS using the METECS built Pong LEE/GF contact/mechanism model and Dynamic State Management (DSM). It also included actual flight software and an HLA ownership transfer of the HTV dynamics between simulations.

With the newly integrated hardware PCS, hand controllers, and DCP, Robotics and Mech instructors were able to perform an HIL capture and install of the HTV. Both the Robotics and Mech instructors had wonderful reviews for progress of the TS21 simulation. They specifically praised the higher fidelity capture and install, as well as the improved integration of Robotics, Mech, Dynamics, and Graphics compared to the legacy training simulation. In addition to our contributions to model and software development, METECS was integral to the integration and testing process.

TS21/MCC-21 Integration Demonstration

The “TS21/MCC-21 Integration” Demonstration involved interfacing the TS21 simulation with the 21st Century Control Center (MCC-21). MCC-21 is a concurrent project to upgrade the Mission Control Center (MCC) architecture. All of the objectives were met during the demonstration including successfully sending commands and receiving data between TS21 and MCC-21. METECS supported the Robotics commanding and graphics for TS21 for this effort.

All three of the above TS21 demonstrations were extremely successful. Multiple METECS employees received “Elite Team Awards” presented by the NASA JSC Software, Robotics, and Simulation Division for their "exceptional effort and technical excellence" in support of these showcase events.

Japanese Exposed Pallet Berthing Mechanism

Requirements for crew training can sometimes quickly and dramatically change. METECS is particularly adept at responding to these time critical projects.

Recently, METECS was approached to provide a simulation model for the Japanese Exposed Pallet "rail and wheel" berthing mechanism. With crew members being moved to different flights due to medical issues, replacement ISS crew needed to be trained to berth this payload on an extremely tight schedule.

Rapid Contact Model Generation using Pong

The Pong contact utility from METECS was used to quickly draw up and export the contact geometry of the rails and wheels required for this training simulation. The dedicated METECS team and Pong utility made this a quick process and drastically reduced the time required to produce and verify the contact model from scratch.

Crew Interface Upgrades

After the simulation model and graphics model were integrated into the Dynamic Skills Trainer (DST) simulation, METECS then built the required FMS overlays that would be needed for the Robotics Workstation (RWS) displays. These overlays were designed, built, and integrated into the DOUG 3D graphics software.


Lastly, upgrades were required to other interfaces to allow the commanding of Force Moment Accommodation (FMA) and FMS sensor calibration.


The METECS effort to quickly build, integrate, test, and verify the EP rail and wheel mechanism model allowed crew training to happen on schedule, and ultimately, helped to lead to the successful robotics operations on orbit.
