The present disclosure generally relates to methods and user interfaces for establishing communications.

Within a satellite communications system, a base station communicates with standard compliant user equipment (UE) via a satellite having a field of view. The base station has a processor that instructs the satellite to generate a wide beam signal covering a plurality of cells in the field of view, and detects an access request from a user equipment within the plurality of cells over the wide beam signal. The base station, comprising a processing device such as an eNodeB, then generates one or more network broadcast/access signals that is uplink to a satellite and broadcasted via one or more nominal beams generated by the satellite, covering all the inactive cells, one of the plurality of cells having the access request.

The antenna includes multiple antenna array elements and multiple phase shifters for calibrating phases of the multiple antenna array elements. The device includes a temperature sensor, a positioning unit and a computing control unit, the temperature sensor is configured to obtain temperature information of the antenna and output it to the computing control unit; the positioning unit is configured to obtain position information of the antenna and output it to the computing control unit; the computing control unit is configured to receive the position information and temperature information of the antenna, determine position information of a satellite, and control the phase shifters to adjust phases of the multiple antenna array elements according to the position information the temperature information of the antenna, the position information of the satellite and pre-stored calibration data.

A ground station processes downlink signals received from respective satellites. The ground station has a plurality of signal conditioning devices each receiving a respective one of the downlink signals and providing a conditioned downlink signal. A plurality of Doppler and/or Delay compensator devices each receive a respective conditioned downlink signal from a respective one of the plurality of signal conditioning devices. The compensator devices conduct Doppler and/or Delay compensation on the received conditioned downlink signal, and provide a compensated downlink signal output. A selector or diversity combiner receives the compensated downlink signal from each of the plurality of Doppler and/or Delay compensators. The selector or diversity combiner selects one of the received compensated downlink signals based on received signal strength of each received compensated downlink signal to provide a selected downlink signal, or diversity combines all of the received compensated downlink signals to provide a diversity combined signal. The selector or diversity combiner provides the selected downlink signal or the diversity combined signal to an eNodeB.

An aggregated communication network includes one or more communication networks and a plurality of network nodes arranged in a plurality of hierarchical layers, the network nodes including a central node at a highest layer and a remaining network nodes being arranged, as part of the one or more communication networks, in layers below the highest layer, with one or more spatially distributed network nodes at each layer below the highest layer. The network nodes in each communication network are interconnected in a tree-like structure via communication links, with respective sub-branches extending from the network nodes via network nodes in lower layers. The one or more communication networks are connected to the central node in a star-like structure via respective communication links between the central node and respective network nodes in a next-to-highest layer. The communication links between network nodes in a lowest layer.

An autonomous vessel and method for transporting a cargo from an origin to a destination utilizing water currents, a satellite location system, and a satellite communication system includes a hull for navigating a body of water. A communication module is adapted for wireless communication with local contacts and the satellite communication system. A propulsion module is adapted to propel the hull through the body of water and preferably includes one or more relatively low-power electric motors. A navigation module is adapted to steer the hull towards a next waypoint. The navigation module preferably includes a rudder control system and is connected with a location module that is itself adapted for communication with the satellite location system to find a current location of the hull on the body of water. A controller is adapted for controlling the modules, sending information, and for receiving commands and information.

A system and method for determining attitude of an end point equipment (EPE) using a global navigation satellite system (GNSS) receiver. The method includes collecting signals and radio frequency (RF) switch states, wherein the signals are GNSS signals received by at least one GNSS antenna of an end point equipment (EPE), wherein the signals are associated with the respective RF switch states; generating differencing data of the signals with respect to reference measurements, wherein the reference measurements are collected from a GNSS receiver at a reference station in a predetermined distance from the EPE; determining an attitude of the EPE based on the generated differencing data; and causing reorientation of the EPE based on the determined attitude.

An adjustable mount for mounting a component subjected to dynamically-varying loads decouples position adjustment of one axis from position adjustment along the other. The mount includes a frame between base and top plates. The frame has apertures for receiving positioners. The positioners abut sides that extend inward from the plates and into the frame. Actuating a positioners causes it to push its corresponding side. This causes relative motion between the frame and the positioner's corresponding plate. Movement interfaces guide these movements during adjustment and locking interfaces lock the frame and the corresponding plate into position after completion of adjustment.

Apparatuses, methods, and systems of hub communication with a satellite network or a terrestrial network are disclosed. One method includes detecting presence of the satellite network, detecting, by the hub, presence of a terrestrial network, selecting to connect to one of the satellite network or the terrestrial network based on a priority ruleset, estimating a propagation delay between the hub and a base station of the satellite network when the satellite network is selected, adjusting a timing offset between transmit and receive radio frames at the hub based on whether the satellite network or the terrestrial network is selected, and based at least on the propagation delay and a fixed frame offset between uplink and downlink frames at base station, and communicating with the base station of the satellite network or a base station of the terrestrial network.

A communications system for line-of-sight (LOS) and beyond-line-of-sight (BLOS) communications using a single aperture includes one or more operators positioned within an environment, wherein each operator includes a common aperture, one or more low-earth orbit satellites communicatively coupled to a plurality of communications sub-systems disposed on the operators. In one embodiment, the communications sub-systems may include a first antenna element to transmit and receive first radio frequency signals along a first directional link via the common aperture. In another embodiment, the communications sub-systems may include a second antenna element to transmit and receive second radio frequency signals along a second directional link via the common aperture.
