Some embodiments operate in context of a bent-pipe satellite that illuminates user and gateway coverage areas with fixed spot beams. Beamforming can be used, along with coordinated, phase-synchronized communication by the distributed access nodes, to generate signals that coherently combine via the satellite. Scintillation and/or other atmospheric irregularities can degrade phase synchronization at the access nodes. Accordingly, embodiments can monitor phase tracking performance of the access nodes to detect when a phase tracking error occurs in at least one of the access nodes. In response to detecting the phase tracking error, embodiments can inhibit transmitting of forward uplink data signals by at least that access node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Scintillation mitigation in geographically distributed satellite access nodes","description":"Systems and methods are described for scintillation mitigation in satellite communications systems with geographically distributed access nodes.
