Ka Conference 2023 - Beam-Hopping and NGSO Signaling Support in DVB Standards

Beam-hopping is an important technology that enables the better utilization of satellite assets for geosynchronous satellites, especially for non-geosynchronous (NGSO) constellations. This technology is matured and is supported in the DVB-S2X standard. With the new amendments to the signaling standards of DVB-SI and DVB-RCS2 for both beam-hopping and NGSO constellations, it can also be integrated into interactive NGSO-based RCS2 systems. This paper describes the signaling elements, provides an estimate for the overhead it introduces and describes a general procedure for connecting a new terminal to an interactive DVB-RCS2 based system.

    Ka Conference 2023 - JOEYSAT: Experimental Leo Ku/Ka Band Satellite to Test Next Generation Technologies in Space

    JOEYSAT is an advanced broadband Ku/Ka Band satellite that was launched into Low Earth Orbit (LEO) on May 20, 2023. It incorporates a fully digital next generation communication payload, made up from a set of digital beamforming antenna arrays coupled with a regenerative on-board processor. The combination of digital beamforming, steering and hopping with powerful on-board digital processing allows the payload to enhance the efficiency and reliability of satellite communication systems suffering from limited bandwidth, high latency, and interference. This presentation outlines the underlying technology elements, the test results obtained so far and the additional tests planned.

      Ka Conference 2021 - Beam Hopping - Deployment Scenarios Analysis

      Beam-hopping was shown to provide a level of flexibility that makes it possible to increase served traffic, reduce areas of unmet demand while enabling the reduction of power consumption on-board. In the paper we study the impact on utilization and capacity, as a function of various deployment parameters, of those features.

        Ka Conference 2021 - Simulation of Tracking Systems for Electronically Steered Antenna Arrays for GEO and LEO satellites

        Electronically steered digital beam-forming antenna arrays have gained significant attraction in satellite communications and 5G applications. Electronical steering has the distinct advantage of not requiring mechanical rotating parts and thanks to digital beamforming, supporting of multiple beams simultaneously is possible unlike analog phase arrays.

                                Ka Conference 2017 - Bounds on Satellite System Capacity and Inter-constellation Interference

                                The ever-increasing demand for data communication traffic, combined with the need for truly global coverage has spurred the introduction of new satellite systems with Low Earth Orbit (LEO) constellations, which are to operate independently, or in conjunction with Geosynchronous Earth Orbit (GEO) satellite fleets.
                                The paper takes a step further in analyzing the total capacity that can be achieved by a satellite system whereby terminals can receive, via multi-beams, several satellites. Thus, making it possible to re-use spectrum and uniformly share the load among multiple satellites.
