Satellite internet constellations deploy large numbers of low earth orbit satellites to provide global broadband connectivity with reduced latency. Inter-satellite links and phased array antennas enable dynamic beamforming and efficient spectrum reuse. Network topology and orbital slot allocation influence coverage and capacity, while handover mechanisms maintain seamless connectivity during satellite movement. Ground station networks interface with space segments, supporting data routing and constellation management. Launch strategies and debris mitigation debe address operational sustainability (not there yet).

Congestion management in satellite-based communications networks
Patent published on the 2026-10-15 in US under Ref US20260322724 by APPLE INC [US] (Talakoub Shahram [us], Seeber Sebastian B [us], Robson Travis J [us], Deo Saurabh [us], Adams Michael E [us], Moore Adam J [us], Williams Ashley M [us], Nelson Gregory R [us], Bhattarai Sudeep [us])
Abstract: [0000] A communications system may include a core network (CN) that communicates with a user equipment (UE) device via a satellite constellation. While a congestion level of a serving satellite in the constellation exceeds a threshold and an uplink message queue is empty, the UE may transmit heartbeat signals with a heartbeat period to signal to the CN that the UE device is still active in its communications session. Receipt of a reverse link signal such as the heartbeat may trigger the CN to re[...]
Our summary: This content discusses congestion management in satellite communications networks. It describes how user equipment transmits heartbeat signals to indicate activity during high congestion. The core network adjusts message priority based on the timing of these heartbeat signals.

Abstract: Earth Observation (EO) and Remote Sensing (RS) data are widely used in various fields, including weather, environment, and natural disaster modeling and prediction. EO and RS done through geostationary satellite constellations in fields such as these are limited to a smaller region, while sun synchronous satellite constellations have discontinuous spatial and temporal coverage. This limits the ability of EO and RS data for near-real-time weather, environment, and natural disaster applications. T[...]
