Systems and methods are provided for calculating satellite access windows for a constellation of imaging satellites. In some implementations, systems and methods are provided for managing execution of native programs on high performance computing systems. In one embodiment a system can determine, for each time interval within a first period of time, a position of each imaging satellite of a constellation of imaging satellites. The system can transform, for each time interval within the first period of time, the position of each imaging satellite from a first coordinate system to a second coordinate system. The system can determine an access window for at least one imagining satellite based at least in part on a determined angle between the vector to the respective location and a determined vector to the respective satellites. The system can schedule the at least one imaging satellite to perform a task within the access window.

The invention relates to a method and a system for determining the capability of a sensor contained in a satellite to access a target region. The position of the satellite is ascertained, the viewing radius of the sensor in the direction of a target reference point in a target region is then determined, the extension of the target region in the direction of a satellite position point is ascertained, and the sensor is determined to be capable of accessing the target region if the distance between the satellite position point and the target reference point in the target region is less than or equal to the sum of the viewing radius of the sensor and the extension of the target region in the direction of the target reference point.

A projection unit (12) of an interference power estimation device (1) projects an orbit of a satellite onto a map representing a ground surface. A range acquisition unit (13) determines a plurality of ranges on the map so that the projected orbit is included in the ranges. An altitude calculation unit (14) calculates an altitude of the orbit of the satellite in each of the ranges. A range interference calculation unit (16) calculates, for each of the ranges, an interference power between the satellite at a position determined by a latitude and a longitude of the range and the altitude calculated for the range and a radio station installed on the ground surface. An estimation result calculation unit (17) selects, as an estimation result, a maximum value among the interference powers calculated for each of the ranges.

A method, computer program product and system where a processor(s) configures sensor(s) on an unmanned aircraft system, to capture data related to a surface of a defined geographic area. The processor(s) navigate the unmanned aircraft system in a repeatable defined travel path proximate to the defined geographic area, such that the sensor(s) capture surface data related to the defined geographic area during the navigating, wherein a position of the unmanned aircraft system in the travel path is within a satellite view geometry of a satellite. The processor(s) maintain the unmanned aircraft system at a distance from the surface at which atmosphere does not obscure the data and obtain the data collected by the sensor(s). The processor(s) compares the data collected by the sensor(s) to data collected by one or more instruments on the satellite related to the defined geographic area to determine is the instrument(s) of the satellite are calibrated.

A method and apparatus for the control of the attitude of earth orbiting satellites and the orbit and attitude control of a novel gravitational wave detection satellite configuration located near the sun-earth Lagrangian points L3, L4 and L5, utilizing the control of solar radiation pressure by the use of electrically controllable variable reflection glass panels to provide the torques and forces needed.

Imaging systems and methods for imaging of scenes in apparent motion are described. A multi-axis positioning mechanism is operable to move an area imaging device along a tracking axis. A control module directs the multi-axis positioning mechanism to set the tracking axis to be substantially parallel with the apparent motion, and directs the multi-axis positioning mechanism to move the area imaging device in one or more cycles such that the area imaging device moves, in each of the one or more cycles, forward along the tracking axis at a tracking speed that compensates for the apparent motion. The control module directs the area imaging device to take at least one exposure during each of the one or more cycles to generate one or more exposures. An imaging module forms an image of the scene based on the one or more exposures.

The present technology relates to an imaging method of a satellite system and a transmission device that enable to perform imaging of an artificial satellite in accordance with an event having occurred on the ground, in remote sensing by the artificial satellite. The satellite system includes: the transmission device installed on the earth; and the artificial satellite having an imaging device. The transmission device transmits an imaging instruction to the artificial satellite passing in the sky, in accordance with a predetermined event detected by a sensor installed on the earth, and the artificial satellite performs imaging of an event occurrence region on the basis of the imaging instruction. The present technology can be applied to, for example, an artificial satellite or the like that performs satellite remote sensing.

A satellite constellation forming system forms a satellite constellation (20) having a plurality of orbital planes (21) in each of which a plurality of satellites fly at the same orbital altitude. A satellite constellation forming unit forms the satellite constellation (20) in which orbital altitudes of the orbital planes (21) are mutually different. Furthermore, in the satellite constellation (20), relative altitude differences between adjacent orbital planes in the plurality of orbital planes are sequentially arranged to be sinusoidal. The satellite constellation forming unit sequentially changes an orbital altitude (23) of each orbital plane of the plurality of orbital planes while maintaining a sinusoidal arrangement of the relative altitude differences between adjacent orbital planes in the plurality of orbital planes.
