A method for managing the telecommunication data traffic of a very high throughput satellite communication system wherein, for each satellite, the management of a so-called n+p site diversity and/or of a load diversity is implemented in a digital transparent processor in the satellite to guarantee the availability of the very high throughput communication system.

Some implementations of the disclosure relate to dynamic switching of a satellite inroute data path between a Time Division Multiple Access (TDMA) method and a Time Division Multiplexing (TDM) method. In one implementation, a method comprises: communicating, using a satellite terminal, over an inroute TDMA channel; determining, at the satellite terminal, based at least on an aggregate ingress traffic rate to the satellite terminal, to switch communications from the inroute TDMA channel to an inroute TDM channel; and after determining to switch communications, sending, from the satellite terminal to a Gateway Earth Station, a request to be allocated an inroute TDM channel.

Systems and methods relating to correction of a Doppler/frequency offset in a wireless communication system are disclosed. In some embodiments, a method of operation of a node comprises estimating a Doppler/frequency offset for a wireless device based on an uplink signal received from the wireless device and providing a frequency adjustment to the wireless device that corrects for the Doppler/frequency offset.

The present disclosure provides a satellite control method and apparatus, comprising: receiving a to-be-photographed target site input by a user; calculating first moment information corresponding to each satellite entering the target site, according to location information of the target site and operation orbit information of the each satellite in a plurality of satellites; and determining, from the plurality of satellites, at least one to-execute satellite to photograph the target site according to the first moment information corresponding to the each satellite entering the target site.

Conventionally, software-based services that utilize satellites are manually and painstakingly configured, provisioned, activated, and calibrated, because the complexity and variability of satellite links prevent automated and scalable service orchestration. Accordingly, systems and processes are disclosed for automated and scalable orchestration of services that utilize satellite links. In response to a service request, comprising a service definition for an end-to-end service, parameter(s) of a satellite link that satisfies the service definition may be calculated. These parameter(s) may be used to select a configuration for a satellite-network service chain, comprising a plurality of virtual network functions, from a service catalog. The satellite-network service chain may then be instantiated, within a cloud infrastructure, using the selected configuration. This process may be implemented in a software-defined network controller which dynamically manages the resources and configuration of the service chain.

A system and method for communicating with an Internet Of Things (IoT) device via a satellite link. The method includes assigning a transmission mode to a physical channel, where the physical channel supports multiple timeslot durations and the transmission mode is selected from a single user (SU) or a multi-user (MU); selecting a timeslot duration from the multiple durations for a payload; obtaining, when the transmission mode is SU, a timeslot grant for use of the physical channel for the timeslot duration; and transmitting a burst including the payload, where the burst is transmitted synchronized with the timeslot grant when the transmission mode is SU and the burst is transmitted without synchronization when the transmission mode is MU.

In a method and apparatus for inter-satellite communications, transmissions between a satellite and neighboring satellites that share an orbital plane occur via an aft antenna or a forward antenna and transmissions between the satellite and neighboring satellites that do not share an orbital plane occur via the aft antenna or the forward antenna timed during orbital plane crossings. This occurs even if the total path length and number of links is higher than inter-satellite communications that use side-to-side transfers.

A method includes receiving request information obtained from an external user. The request information is associated with a task to be completed by at least one satellite asset among a plurality of satellite assets, where the satellite assets are grouped into a plurality of constellations and each of the constellations is associated with a corresponding scheduler among a plurality of schedulers. The method also includes assigning the task to a queue. The method further includes determining at least one specified scheduler to schedule the task at the at least one satellite asset. In addition, the method includes sending instructions to the at least one specified scheduler for performing the task by the at least one satellite asset.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a transmission frequency for an uplink transmission based at least in part on a reference point for the uplink transmission, the reference point being associated with one of: a satellite that provides a cell covering the user equipment, the satellite being associated with a non-terrestrial network, or a gateway associated with the satellite; and transmit the uplink transmission based at least in part on the transmission frequency. Numerous other aspects are provided.
