      1. Flight Dynamics as a Service (FDaaS)
        Nautilus provides a comprehensive, all-in-one FDaaS solution that simplifies mission operations and ensures precise navigation and flight dynamics support. Covering every orbit and phase of a mission—from concept to operations—FDaaS offers a seamless and integrated solution for mission success. This service includes:-FDS Design and Implementation: design, development, and implementation of tailored Flight Dynamics Systems (FDS) to meet the unique requirements of each mission

        -Mission Analysis: Advanced simulations and trajectory designs optimize orbital paths, ensuring fuel-efficient operations and alignment with mission objectives.

        -Ground Operations: Our specialized flight dynamics operations team ensures real-time orbit determination, maneuver planning, and navigation analysis to keep satellites aligned with mission requirements.

        -Mission Data Processing: sophisticated tools process telemetry and orbital data into post-mission insights enhancing future mission planning and identifying potential optimizations for satellite performance and design.

      2. On-Ground Navigation Solutions
        NEMO is Nautilus’ powerful software suite designed to automate mission design, navigation, and operations:-NEMO Home: For LEO, MEO, and GEO missions, NEMO Home automates orbit determination, GNSS filtering, collision avoidance, and maneuver planning. It enables effective constellation management and improves operational efficiency.

        -NEMO Nexus: Tailored for lunar missions, Nexus supports cislunar navigation, station-keeping near Lagrange points, and orbital transfers. It also integrates Lunar SSA tools, ensuring optimal asset management in the lunar environment.

        -NEMO Journey: Ideal for deep-space exploration, Journey provides advanced tools for asteroid navigation, proximity operations, and orbit insertions. With integrated ground station scheduling, it optimizes communication in high-latency environments.

      3. On-Board Navigation Technologies
        Nautilus leverages Autonomous Radiometric and Optical Navigation to empower on spacecraft with on-board precise orbit determination, guidance, and autonomous proximity operations. By integrating GPS and ground-based radiometric observables optical sensors, and inter-satellite communication, these systems enable autonomous decision-making in a wide range of scenarios, from crowded LEO environments to articulated deep space operational profiles.- EON: redefines on-board collision risk assessment. It performs real-time conjunction analysis, reducing false positives and eliminating unnecessary maneuvers to conserve fuel. EON also enables inter-satellite coordination, improving constellation performance and extending satellite lifespans. EON represents a major leap forward in autonomous satellite navigation, reducing reliance on ground control while enhancing mission safety and efficiency.

        4. Ground Testing Equipment: CubeDynA
        CubeDynA is Nautilus’ advanced ground testing platform, specifically designed to validate and enhance the performance of nanosatellite systems by recreating realistic in-orbit conditions. Developed in collaboration with the University of Bologna, CubeDynA has been developed for the European Space Research and Technology Centre (ESTEC) of the European Space Agency (ESA).

        -Testing Capabilities: CubeDynA supports closed-loop testing of CubeSat Attitude Determination and Control Systems (ADCS) for platforms ranging from 1U to 12U (with future support for up to 16U).

        -Space Environment Simulation: The facility recreates key conditions that influence satellite attitude dynamics, including Earth’s magnetic field, solar radiation flux, and Earth’s albedo.

        - Real-Time Attitude Estimation: CubeDynA provides real-time ground truth attitude measurements, which can be used to simulate surrogate star tracker outputs and enhance CubeSat navigation algorithms.
