OVERVIEWBraxton’s Flight Dynamics System (AceFDS) is a powerful and versatile software toolset providing full-lifecycle flight dynamics capabilities. FDS adds value to your flight dynamics requirements throughout any phase of the mission from Launch through Disposal. FDS seamlessly accommodates the internal mission design cycles from Estimation, Prediction, Maneuver Targeting, Calibration, and Reconstruction. Unique to FDS is the ability to perform real-time orbit and attitude determination along with continuous Ion and Propellant maneuver planning. Extensibility is inherent to our design, as FDS allows for tailoring to mission specific capabilities. Our flexible approach to product packaging and deployment facilitates its use in Research, Design, and Real-time Environments.

FLIGHT DYNAMICS SYSTEM

CAPABILITIES• Orbit Determination: Performs estimation of spacecraft orbits based on the weighted batch least square algorithm using

AceFDS simulated tracking data or actual ground station data.

• Attitude Determination: Performs estimation of spacecraft spin-stabilized attitude based on the weighted batch least square

algorithm using as input AceFDS simulated or actual sensor.

• KF Orbit Determination: Performs sequential estimation of spacecraft orbit using a Kalman Filter, as well as estimation of

tracking measurement biases and other miscellaneous parameters.

• Maneuver Planning: When targeting a specific and/or desired orbit, FDS provides the ability to create sequenced plans

for spacecraft maneuvers including delta-V, spin precession, and spin rate change, using chemical propulsion systems.

• Station-Keeping: Provides the ability to analyze the long-term behavior of orbit drifts due to perturbations and to target a

maneuver to maintain the satellite within the assigned orbital box.

• XIPS Maneuver Planning: Provides the ability to create sequenced plans for spacecraft maneuvers using a generic Xenon

Ion Propulsion System.

• Maneuver Calibration: Calculates individual thruster performance factors based on pre and post maneuver states.

• Maneuver Reconstruction: Provides the ability to reconstruct maneuver profiles based on simulated or actual telemetry data.

• Element Conversion Tool: Provides an element set and coordinate frame conversion capability either from values entered

by the user or imported from saved states.

• Vehicle Specification Management Tool: Provides the ability to ingest and manipulate a set of data files comprising

the vehicle specification. Upon completion of a vehicle ingest operation, the data is converted to a format and naming

convention for used by all FDS tools.

• Operational Database Management Tool: Provides the ability to export or ingest entire saved operational databases as

well as manage elements of the operational database.

• Data Analysis Tool: Provides the ability to generate plots or tables of any data collected or simulated in FDS and the ability

to modify and configure those plots and tables.

• Simulation: Provides the ground station, sensor, and telemetry simulators to mimic real world environments.

• Interactive Mission Scheduler: Provides for automated task scheduling and visualization.

• Centralized Database: Enables interactive collaboration, ensuring all users work with the same data; allows system

administrators a common data ingestion point, and facilitates data mining capabilities to perform trend analysis and

anomaly detection.

• Visualization: 2D and (Optional) 3D Visualizations enhance understanding of the overall mission through X-Y graphing,

plotting, and vehicle specific displays.

• Form Templating: Allows users to save and reload templates of common missions which reduce User Data Entries and

Increases Productivity and Performance.

• External Interfaces: TCP/IP interfaces allow interoperability with 3rd Party and Legacy Tools to accommodate integration

with other systems.

• Standard Libraries: SOFA, CSpice, MSISE00, WGS-84 ensures compliance, accuracy, and acceptance.

• Supporting Functions: Provides Data Stream Collection, Monitoring of System Status, and User Administration.

• Deployable in a Microsoft Windows or Linux environment.
