47 results about "Space launch" patented technology

Space launch is the earliest part of a flight that reaches space. Space launch involves liftoff, when a rocket or other space launch vehicle leaves the ground, floating ship or midair aircraft at the start of a flight. Liftoff is of two main types: rocket launch (the current conventional method), and non-rocket spacelaunch (where other forms of propulsion are employed, including airbreathing jet engines or other kinds).

Systems, methods, and devices for dynamically identifying launch opportunities for a space vehicle. A space launch service platform (SLSP) receives time-stamped positional data from an external tracking system monitoring aircraft, maritime vessels, or orbital objects. The SLSP synchronizes received positional data to a unified timeline using a common reference clock. At predetermined intervals, the SLSP calculates predicted future positions of monitored objects by extrapolation. The SLSP calculates predicted proximities between a predefined launch trajectory—defined within an Earth-centered inertial coordinate system—and each predicted future position. The SLSP determines a risk index for each predicted proximity. The SLSP identifies discrete launch windows within a specified launch period where predicted proximities exceed a clearance threshold and associated risk indices remain below a risk threshold. The SLSP aggregates contiguous discrete windows into at least one continuous launch interval and generates a launch opportunity indication associating each interval with a launch readiness signal.
