    Abstract: A high data rate distribution network for low-earth orbit (LEO) satellite constellations is described. The high data rate distribution network includes multiple LEO constellations, each constellation including a number of LEO spacecraft orbiting in a LEO plane that are all connected together by by-directional free space optical links. The distribution network further includes geostationary earth orbit (GEO) spacecraft in communication with a number of ground gateways. The GEO spacecraft can receive forward communication traffic including radio-frequency (RF) and/or optical data streams uplinked from the ground gateways and can convert the received forward communication traffic into a forward aggregated traffic. The GEO spacecraft can further optically downlink the forward aggregated traffic to LEO spacecraft in a LEO constellation that is in line of sight of the GEO spacecraft. The forward aggregated traffic is then disaggregated among and received by the LEO spacecraft in the LEO constellation. Return communication traffic from each LEO spacecraft can also be aggregated into a return aggregated traffic from the LEO constellation. The return aggregated traffic is optically uplinked to a GEO spacecraft by a LEO spacecraft of the LEO constellation that is in line of sight of the GEO spacecraft. The GEO spacecraft converts the received return aggregate traffic into multiple RF and/or optical data streams that are down linked to a number of ground gateways.

    Abstract: There is provided a method for detecting flying object launching using a surveillance system and a communication system and transmitting flying object information to a coping system in quasi-real time.
    A plurality of satellite constellation business apparatuses (430) which manage individual satellite constellations, each having eight or more communication satellites (200) on one orbital plane (90), are present. All of the individual satellite constellations form a satellite constellation (610) which is a unified satellite constellation with eight or more orbital planes. Communication satellites (200) on a same orbital plane each form cross-links with communication satellites ahead and behind. Communication satellites on adjacent orbital planes each form cross-links with communication satellites in left and right adjacent orbits. The plurality of satellite constellation business apparatuses (430) construct a total of N orbital planes (90) and form a mesh communication network in collaboration.

    Abstract: A method of routing communication among nodes and systems of an interplanetary network on an ad-hoc basis is described herein. For example, the communication routing described herein may not be pre-determined or static, but rather determined dynamically on a periodic basis, as transmission conditions change, as nodes are added or removed from the interplanetary network, periodically, and/or the like. The interplanetary network may include one or more nodes that have static and/or dynamic states. A node can include any extraterrestrial object or communication relay. The interplanetary network may also include one or more ground stations, which can include communication equipment (e.g., antennas, radar, transmission towers, etc.) located on Earth. To enable the ad-hoc communication routing, a ground station system and/or another processing device can continuously or periodically obtain orbital parameters from one or more nodes in the interplanetary network and generate updated contact plans.

    Abstract: A second monitoring device includes a +X+Y sensor (11S) directed at +45 degrees, a +X−Y sensor (12S) directed at −45 degrees, a −X+Y sensor (13S) directed at +135 degrees, and a −X−Y sensor (14S) directed at −135 degrees. When flying northeastward, the second monitoring device monitors airspace above high latitudes in the Northern Hemisphere with the +X−Y sensor (12S), and monitors airspace above high latitudes in the Southern Hemisphere with the −X+Y sensor (13S). When flying southeastward, the second monitoring device monitors airspace above high latitudes in the Northern Hemisphere with the −X−Y sensor (14S), and monitors airspace above high latitudes in the Southern Hemisphere with +X+Y sensor.

    Abstract: A satellite system may have a constellation of communications satellites that provides services to users with electronic devices such as portable electronic devices and home and office equipment. A network operations center may use gateways to communicate with the satellite constellation. The satellite constellation may include sets of satellites with different orbits such as circular orbits with different inclinations, sets of satellites with elliptic orbits, sets of satellites with circular orbits of different altitudes including low earth orbits, medium earth orbits, and/or geosynchronous orbits, and/or sets of satellites with other orbits. The satellite orbits of the satellites in the satellite constellation may be selected to provide coverage to desired user population concentrations at different locations on the earth without using an excessive number of satellites.
