A satellite constellation forming system (100) forms a satellite constellation which is composed of a satellite group and in which the satellite group cooperatively provides a service. The satellite constellation has a plurality of orbital planes in each of which a plurality of satellites fly at the same nominal orbital altitude. A satellite constellation forming unit (110) continues providing the service while avoiding a collision between satellites by both or one of control of an orbital altitude and control of a passage timing of a satellite group flying in a region where the plurality of orbital planes intersect.

A system for providing air traffic control within a geographic sector to which a communication frequency in the VHF or UHF range is assigned comprises at least one satellite (configured for a communication with an aircraft in the geographic sector using an analog modulated RFF signal at the communication frequency. The system is configured in such a way that at each time, only one satellite is actively transmitting on the communication frequency assigned to the geographic sector.

Methods and techniques are described for supporting satellite wireless by a user equipment (UE) using satellite acquisition information. A UE may obtain (e.g., from an AMF or gNB) acquisition information for satellite cells supporting access to a PLMN. The UE may enter an inactive state with no radio access, may later leave the inactive state, find a preferred satellite cell based on the acquisition information and access the satellite cell (e.g., camp on the cell or connect to the PLMN using the cell). The acquisition information may indicate satellite cells available at one or more predefined times for a known location of the UE or may enable a satellite cell to be found for any UE location at any time. The acquisition information may also provide timing, frequency and other information to enable a UE to access a satellite cell with reduced latency and reduced power consumption.

A method, including receiving a search query for resources that are configured to establish a connection with a space vehicle, the search query including a first value for a connection parameter; identifying one or more tactic definitions that satisfy the search query, each of the tactic definitions including one or more second values for the connection parameter, wherein at least one of the second values for the connection parameter matches the first value for the connection parameter that is included in the search query; and generating one or more tactic options, each of the tactic options being generated based on a respective one of the tactic definitions, each of the tactic options being associated with a respective resource of the tactic option.

A system for aggregating spaced related systems includes accessing service provider information for multiple service providers to determine relevant services/systems available, automatically determining that no single service provider provides services sufficient to perform a particular space activity, automatically identifying multiple services from different service providers that in aggregate include performing the space activity, and automatically determining a parameter to configure space equipment to perform each of the multiple services from the different service providers in order to perform the space activity. In some embodiments, this system can be scaled across multiple regions (e.g., multiple planetary regions). For example, each region can have its own set of servers and ledgers that provide real-time services within the region and opportunistically synchronize between regions (e.g., when communication is available).

Systems, methods, and apparatus for satellite operations with secure enclave for secure inband hosted payload operations are disclosed. In one or more embodiments, a method for payload operations comprises receiving, by a vehicle, host commands from a satellite operation portion of a host spacecraft operations center (SOC). The method further comprises reconfiguring a payload and at least bus component on the vehicle according to the host commands. Also, the method comprises transmitting, by the vehicle, host telemetry to the satellite operation portion of the host SOC. In addition, the method comprises receiving, by the vehicle, hosted commands from a secure enclave of the host SOC. Additionally, the method comprises reconfiguring the payload on the vehicle according to the hosted commands. Further, the method comprises transmitting, by a payload antenna on the vehicle, host payload data, hosted payload data, and the encrypted hosted telemetry to the secure enclave.

A system and method are disclosed for providing single-hop communication sessions in a satellite network. A timing offset is selected based on a system timing reference, and used to establishing a common timing reference. A synchronization signal is transmitted from a gateway to a satellite based on time slots aligned with the common timing reference, and subsequently forwarded from the satellite to all terminals managed by the gateway. Communication sessions are initiated by terminals using the common timing reference, and downlink transmissions from the satellite to the terminals are aligned with the synchronization signal.

An orbiting multiple access transceiver communicates with terrestrial mobile stations which are also capable of communicating with terrestrial base stations. The multiple access transceiver is configured to sample a signal when a terrestrial mobile station of interest is not transmitting to produce a sample signal. The sample signal may be processed to produce an out-of-phase signal that may be applied to a signal when the terrestrial mobile station of interest is transmitting to produce a clearer signal from the terrestrial mobile station of interest.

Apparatus, methods, and computer-readable media for facilitating on-demand ephemeris and beam information requests are disclosed herein. An example method for wireless communication at a UE includes transmitting a request for requested information, the requested information including one or more of system information and satellite information. The example method also includes receiving a response message based on the request, the response message including one or more of: an NTN system information block, satellite information associated with at least one requested communication satellite, and beam information associated with the at least one requested communication satellite.

Aspects of the subject disclosure may include, for example, a device that has a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, including receiving a request for an observation of an overhead viewing area from an observer location; discovering an interference of a satellite with the observation of the overhead viewing area; determining possible solutions to the interference; selecting a solution of the possible solutions; receiving the observation from one or more satellites responding to the solution selected; and providing a response to the request including the observation received. Other embodiments are disclosed.
