    Abstract: Systems and methods are described for enabling flexible signal pathways within a satellite of a satellite communications system. For example, a pathway selection subsystem in a bent-pipe satellite enables a flexible arrangement of non-processed signal pathways that couple uplink antenna ports with downlink antenna ports via uplink and downlink pathway selectors. The pathway selectors can be dynamically reconfigured (e.g., on orbit), so that the configuration of the pathway selectors at one time can form one set of signal pathways between respective uplink and downlink antenna ports, and the configuration at another time can form a different set of signal pathways between respective uplink and downlink antenna ports. The pathway selection subsystem can have a simulcast mode which, when active, couples each of at least one of the uplink antenna ports with multiple of the user downlink antenna ports to form one or more simulcast signal pathways.

  • Patent number: 10880765
    Abstract: An apparatus is provided for measuring the performance of a mobile communication system. The apparatus includes two measurement mobile interfaces and a measurement probe. The probe is connected to the backhauling interface of a base station of the system. Then, one measurement mobile interface transmits packets to the other measurement mobile interface via the base station. These packets are received at the base station, forwarded to the packet gateway of the system, sent back to the same base station, and finally received at the destination measurement mobile interface. Since the measurement probe belongs to the same apparatus as the mobile interfaces, it may detect the packets as transmitted/received at the backhauling interface. The probe then generates performance parameters relating to the packets as transmitted/received by the mobile interfaces and/or as detected at the backhauling interface. The system performance is then measured based on such parameters.

  • Patent number: 10826598
    Abstract: A satellite communication system may include a terrestrial station and a satellite having a communication link therebetween. The terrestrial station may include a controller and a transceiver cooperating therewith and configured to determine a degradation of the communication link, obtain satellite-derived, rainfall rate and rainfall height data, and determine a rain fade for the communication link based upon the satellite-derived, rainfall rate and rainfall height data. When the degradation of the communication link is caused by the rain fade, the controller determines a mitigation action for the satellite and communicates the mitigation action to the satellite.

  • Patent number: 10644400
    Abstract: A host processor controls an apparatus by updating all the phase shifter values of a phased array antenna by using “global write” to update these parameters to all phased-array transformation circuits simultaneously via a serial bus. Antenna elements, each controlled by a phased-array transformation circuit, are individually configured to transform phase and gain according to a register array. The register array has a local register group and a central register group, the local registers physically placed close in proximity to RF chains which each correspond to an element of array antenna, whereby each set of local registers control an individual antenna element and a central register controlling overall beam steering function. The apparatus is transformed by the host efficiently elaborating phase shift weights into a submodule of a phase array antenna system with low noise and bandwidth. The host triggers reuse of phase and gain when it can.
