Flight Dynamics Operations
In the context of modern space operations, especially with the proliferation of LEO mega-constellations, the role of spaceflight dynamics operations has become increasingly critical. This field ensures the safe and efficient navigation of satellites. Its core activities include routine tracking and monitoring of spacecraft location, determining their precise trajectory, predicting their future path, planning maneuvers, mitigating collision risks, and maintaining their desired orientation.
Effective management of these operations is vital for the long-term sustainability of space activities by reducing the risk of collisions and mitigating space debris creation. This promotes a more sustainable space environment for future missions. At GlobaNav Solutions, we excel in navigating the complexities of space and have extensive experience in low Earth orbit (LEO) spaceflight operations.
We invite you to explore our publications, where we share detailed insights and findings from our work in this critical field.
Satellite mission: TerraSAR-X
Mission Objective: Make multi-mode and high-resolution X-band data available for a wide spectrum of scientific applications. Acquire 2D SAR observations in the operational modes Stripmap, ScanSAR and Spotlight.
Operational Altitude: 514 km
Our Contributions: Following the successful launch and insertion of TerraSAR-X into its target orbit, the flight dynamics team achieved a key milestone: demonstrating the satellite's ability to precisely maintain its position within the designated control zone. The validated ground-based automated GPS-based precise orbit determination and maneuver calibration system, together with the attitude determination process, contributed to the success of precision station-keeping of the satellite within its stringent control parameters.
