摘要： Technology for facilitating position determination is disclosed. A satellite with a known location can activate a light source on the satellite operable to emit light. The satellite can emit the light for a defined period of time to enable a receiver to detect the light and determine a geographical location using the light emitted from the satellite.

摘要： Passively measured NEO bearings are used to augment an existing navigation system on-board the platform to correct the position estimate generated by the navigation system. The technology provides only a position correction based on passive NEO sightings but is applicable to a wide variety of platforms with different maneuvering profiles and update requirements. The technology directly calculates a position error based on the current position estimate and the passively measured and estimated bearings to three or more NEOs and provides the position error to the navigation system as a correction to the position estimate. The estimated bearings are computed from the current position estimate and the known orbits of the NEOs. The position error may be calculated from a single observation of multiple NEOs, allowing for frequent updates as needed and placing no restriction on platform maneuverability.

摘要： A sabot is used for enclosing a payload, such as a missile or projectile, during launch. The sabot includes a series of panels that are held together prior to launch by engagement with a cap having protrusions or delay pins that maintain the panels in a closed condition. When the launch is initiated, the cap begins to slide out of engagement with the panels. The cap is configured such that the disengagement does not occur immediately upon movement of the cap; instead the protrusions are sized to delay opening of the panels until the sabot and missile have cleared the launcher. Then the panels rotate outward and drop away from a base the sabot, for example using self-releasing hinges. The base of the sabot may be configured to disengage from the payload by introduction of pressurized gases into a space between the base and an aft end of the missile.

摘要： An obturator can be secured to a projectile to be launched from within a launch tube. The obturator cooperates with the projectile to seal a pressurized gas within the launch tube during launch. The obturator has a plurality of segments that combine to form a ring. Each segment has connecting features that cooperate with corresponding connecting features of an adjacent segment to hold the segments together by restricting relative circumferential movement, without restricting radially outward movement of individual segments. Preferably, each segment is identical, making it easier to repair and assemble the obturator. Upon launch, the obturator segments can move radially outwardly to separate into relatively small, uniformly-sized pieces.
