Trajectory and orbit analysis is critical to the success of all space missions. For many years, Defense Technology Systems has provided pre-mission and real-time support in these activities for NASA's earth-orbit missions.

Typical trajectory and orbit analysis for planning and operational activities includes the following:

• Launch Windows
• Flight Trajectory
• Vehicle Constraints
• Range Safety
• Ascent Design
• Tracking Geometry
• Target Selection
• Attitude Design
• Communications Coverage
• Plume Impingement
• Reentry Analysis
• Post-Flight Data Analysis

Defense Technology Systems has standard and proprietary tools for these and related types of analyses. Our capabilities have been proven repeatedly on Space Shuttle and other flights.
