Abstract: The invention relates to an imaging system for imaging a surface on an astronomical body, such as the Earth. The imaging system such as a satellite imaging system comprises a telescope comprising at least first and second curved mirrors wherein the second mirror is located downstream of the first mirror, relative to a propagation direction of imaged light, a digital image sensor or a slit aperture arranged at the focal plane of the telescope, and an actuator system arranged for tilting the second mirror or other curved mirror located down-stream of the first curved mirror for scanning the line of sight of the imaging system in a scanning direction (221) on the surface within a field of view (231) of the imaging system.

Abstract: Computer systems (100) for satellite image acquisition and mission-plan calculation devices (120) for satellite and also Earth observation satellites (110). Based on the observation that the uncertainty connected with meteorological conditions can lead to the development of mission plans, for satellites, with low effectiveness, the uncertainty is characterized and used to improve the preparation of mission plans for satellite. A model of the uncertainties is built upon observations and/or past meteorological forecasts. Next, at the time of planning, the model is used by presenting the observations and/or the current forecast as input to the model. In that way, the acquisition zones for which it is unlikely to get acceptable images on the preferred acquisition date may be identified.

Abstract: A surveillance satellite that has detected a significant high luminance generates launch sensing data indicating a launch time point corresponding to a detection time point, a launch coordinate value expressing a position at which the significant high luminance was detected, and a line-of-sight vector at the detection time point and containing surveillance data at the detection time point and transmits the launch sensing data. A communication satellite that passes through a point in a communication range with respect to the surveillance satellite to transmit the launch sensing data receives the launch sensing data and transmits the launch sensing data to remaining communication satellites via a satellite communication network.

Abstract: A flying object (109) flies on the earth's limb. Three or more surveillance satellites (120) monitor the earth's limb from different latitudes than each other at a time of interest and transmit three or more sets of monitoring data. A ground system (130) receives the three or more sets of monitoring data, calculates three or more line-of-sight directions from the three or more surveillance satellites to the flying object at the time of interest based on the three or more sets of monitoring data, calculates flying object coordinate values indicating the position of the flying object at the time of interest based on the three or more line-of-sight directions, and selects one flight path model from multiple flight path models based on the flying object coordinate values.

Abstract: A surveillance satellite (100) of a surveillance system (310) transmits flying object information, which is generated by monitoring a flying object (520), to a coping system (330) via a communication satellite (200) of a communication system. A defense information integration center (350) includes a communication route search device (470) for satellite information, a flight path prediction device (5490) predicting a flight path of a flying object, and a coping asset selection device (333). The defense information integration center (350) transmits an instruction command to a surveillance satellite group included in the surveillance system (310), a communication satellite group included in the communication system (320), and a coping asset (332).

Abstract: A system includes a plurality of satellites in orbit around a celestial body in a plurality of orbital planes. Each satellite includes an imaging device having a field of view (FOV) to capture an image of a sky that includes celestial image features of resident space object (RSO), stars, and/or planets. The satellite processor is configured to receive image data from sensors in the imaging device, to increase a positional detection accuracy of the celestial image features by defocusing imaging optics of the imaging device, to capture image data in a volume of the sky as the FOV of the imaging device on each satellite moves in an orbital plane, and generate by a centralized computer at least 1,000 celestial image features using the image data transmitted from each of the satellites.

Abstract: 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.

Abstract: A universal test port is connected to the different functional sub-systems of a spacecraft, allowing the sub-systems to be tested from a single location of an assembled spacecraft. The universal test port is mounted on an external surface of the spacecraft and configured to connect to the different functional sub-systems (such as power, propulsion, and command and data handling, for example) of the assembled spacecraft, allowing for the streamlining of testing operations by electrical ground system equipment during assembly, integration, and test (AIT) operations and reducing the risk of collateral damage to spacecraft hardware during testing in AIT.
