• Improved collision avoidance: Precise knowledge of satellite positions allows operators to predict potential collisions or close approaches with other objects in space. Prompt alerts based on this data facilitate timely evasive maneuvers to avoid any dangerous encounters.
• Optimized resource allocation: Efficient orbit determination techniques enable better utilization of fuel reserves by minimizing unnecessary trajectory adjustments. This results in extended satellite lifetimes and cost savings for operators.
• Increased mission success rate: Reliable orbit determination helps ensure that satellites are positioned accurately within specified orbital slots or assigned targets. This enhances the chances of successful payload deployment, communication link establishment, and other critical operations.

The table below summarizes some significant advancements in satellite orbit determination technology:

In conclusion, advancements in orbit determination technology have significantly transformed the aerospace and defense satellite industry. The utilization of technologies like GNSS, laser ranging, and satellite-to-satellite tracking has revolutionized how we determine satellite orbits with unprecedented precision. These innovations not only enhance operational efficiency but also contribute to increased mission success rates, improved collision avoidance capabilities, and optimized resource allocation. As technology continues to evolve, future trends in satellite orbit determination are poised to further expand our understanding and control over space assets.
