摘要： A space information recorder (100) acquires space object information (500), which is orbit forecast information of a plurality of space objects (60), from a management business device (40) used by a management business operator that manages the plurality of space objects (60), and records the space object information (500). The space object information (500) includes a forecast epoch, a forecast orbital element, and a forecast error of each of the plurality of space objects (60). When it is foreseen that a space object A included in the plurality of space objects (60) will intrude into a range at orbital altitudes of 300 km to 1000 km in which a satellite group of LST 10:00 to 11:00 is present, a time period from intrusion to exit and orbit forecast information are recorded.

摘要： An object is to assist an appropriate avoidance action when a collision between space objects in outer space is foreseen in advance. A storage unit (140) stores orbit forecast information (51), which is a forecast value of an orbit of each of a plurality of space objects. An alert control unit (120) determines whether space objects whose locations at the same time are in a dangerous relationship exist as danger-anticipated objects among the plurality of space objects, based on the orbit forecast information (51). When it is determined that the danger-anticipated objects exist, the alert control unit (120) outputs a danger alert indicating existence of the danger-anticipated objects. When the danger alert is output, an avoidance decision unit (150) decides an avoidance space object, which is a space object to perform an avoidance operation, out of space objects included in the danger-anticipated objects.

摘要： Metamaterials are employed with satellites, e.g., small satellites, to increase the observability of such satellites. Any type of suitable metamaterial can be used. In exemplary embodiments fractal-based patterns or structures may be used. A super scatterer having a metasurface is employed for the satellite and enhances the radar reflection for a given area of the satellite. Such detection can be used for monitoring and/or controlling the orbits of satellite space craft.

摘要： The invention concerns a suborbital space traffic control system that comprises: a radar system configured to monitor a predetermined suborbital region and detect and track objects in the predetermined suborbital region. The objects include vehicles and space debris; and a suborbital space traffic monitoring system configured to: receive, from the radar system, tracking data related to the objects detected and tracked by the radar system; monitor, on the basis of the tracking data, trajectories of the objects in the predetermined suborbital region using one or more predetermined machine-learning techniques to detect potentially hazardous situations for the vehicles in the predetermined suborbital region; and, if it detects a potentially hazardous situation for one or more given vehicles, transmit corresponding alarm messages to the given vehicle(s).

摘要： A system detects a maneuver of at least one space object by receiving a first data set relating to orbital characteristics of at least one space debris object. The system trains a model, using the first data set, in order to model orbital behaviors of the at least one space debris object. The system then receives a second data set relating to orbital characteristics of the at least one space object, and detects a maneuver of the at least one space object using the trained model and the second data set.

摘要： An embodiment of the present invention is a system (and concomitant methods and computer software embodied in non-transitory computer readable media) providing formations of satellites and a method of modeling and analyzing inter-satellite relative motion of more than one satellites. These extensions include factoring in spacecraft flight dynamics for achieving real-life and/or simulated objectives.

摘要： The present invention relates to an aerospace vehicle navigation and control system comprising a terrestrial illumination matching module for determining spacecraft position and attitude. The method permits aerospace vehicle position and attitude determinations using terrestrial lights using an Earth-pointing camera without the need of a dedicated sensor to track stars, the sun, or the horizon. Thus, a module for making such determinations can easily and inexpensively be made onboard an aerospace vehicle if an Earth-pointing sensor, such as a camera, is present.

摘要： The disclosure herein relates to a receiver for use in a user satellite, located among other things partly or wholly on orbits remote from Earth, for example. The receiver comprises a receiving unit and a processing unit. The receiving unit is configured to receive signals transmitted by navigation satellites of one or more global navigation satellite systems (GNSS). The processing unit is configured to determine measurements based on the data contained in the signals received. The processing unit is further configured to carry out a calculation of position, velocity and time (PVT) based on batch processing of the measurements. The disclosure herein further relates to a method and a user satellite.
