Abstract: A constellation of many satellites are actively maneuvered to maintain specified non-geosynchronous reference orbits. Each satellite is assigned a slot within a particular reference orbit. For each reference orbit, a set of orbital parameters including eccentricity and argument of perigee for frozen orbits are selected that are unique relative to other reference orbits in use. One characteristic of a frozen orbit is that at a given point in the orbit, altitude is relatively constant. At points where orbital planes of the reference orbits intersect, the differing sets of orbital parameters assure a vertical separation between satellites in different orbital planes is maintained without the need for evasive maneuvers. Actual orbital motion data is obtained from sensors onboard each satellite. The desired orbital parameters are maintained based on the actual orbital motion data as part of scheduled maneuvers to maintain the reference orbit assigned to that satellite.

Once detected, actions may be taken, such as notifying the user.

Abstract: Systems and methods are described for modifying input and output (I/O) to an object storage service by implementing one or more owner-specified functions to I/O requests. Different data manipulation functions can be placed in different I/O paths depending on the request method or user access level. For example, a user having full access may be returned the unaltered version of the object, whereas a user having modified or reduced access may be returned a modified or redacted version of the object. In this manner, owners of the object collection are provided with greater control over how the object collection is accessed.

Abstract: To determine whether a request or an associated response is cached, the request may be received by a first server associated with a Content Delivery Network (CDN). Based on configuration data for the server, a header is generated based on characteristics of the request, indicating that a response associated with the request is able to be cached. A second server associated with generation of a response receives the request. In response to the header, the second server generates a caching determination based on configuration data and the characteristics of the request. When the first server receives the response and the caching determination, the response may be stored. Use of the second server to generate caching determinations eliminates the need to change the configuration of devices associated with the CDN while enabling requests from multiple CDN devices to be cached without requiring changes to be deployed to each device.

The target vision server queries a target information server in order to access, filter and provide the real-time target location information required by the electronic vision device. A surveillance system of sensors and target tracking systems provides the target information server with target location information.
