Our team at Logos is comprised of highly skilled engineers with extensive backgrounds in networking and satellite technologies, ensuring that we push the boundaries of what's possible in satellite connectivity.
Position Overview
In the role of Precise Orbit Determination Engineer, you will spearhead the architecture and software development for the ground-based orbit estimation service within the Logos Space satellite network. Your responsibilities will include processing a variety of tracking data, such as GNSS observations and ground station ranges, to accurately reconstruct and forecast satellite ephemerides. This critical work facilitates the seamless scheduling of operations and maintenance across the Logos Space constellations.
Key Responsibilities
- Estimation Architecture: Architect and sustain the ground-based Orbit Determination (OD) pipeline utilizing Extended Kalman Filtering (EKF), Least Squares, or comparable batch estimation frameworks.
- High-Fidelity Modeling: Develop and implement advanced force models including high-degree gravity fields, solar radiation pressure, atmospheric drag, and third-body perturbations to achieve superior prediction accuracy, along with clock parameter estimation.
- Data Fusion: Create algorithms to integrate and fuse GPS/GNSS and similar PNT source telemetry with ground-based ranging data, producing robust and precise satellite ephemeris estimates.
- Calibration & Validation: Regularly perform cross-calibration analyses between ground-truth POD and onboard navigation systems to ensure consistency across the fleet.
Qualifications
- Education: MS or PhD in Aerospace Engineering, Geomatics, or Physics, specializing in Estimation Theory or Astrodynamics.
- Experience: A minimum of 5 years of experience in orbit determination for LEO satellites.
