System and architecture for space-based and mobile terrestrial sensor vehicles, and end-to-end network for aggregation and processing of sensor data
TL;DR: In this paper, a system for reducing latency data collection from space-based sensor satellites is presented, where a relay satellite terminal is configured to execute data communications via a communications channel of a first satellite beam, wherein the data communications are configured to relay the sensor data, via satellites, to respective gateways for forwarding to a central processing facility for aggregation, processing, analysis and dissemination of the data.
Journal ArticleDOI
Architectures for next generation high throughput satellite systems
TL;DR: A model to estimate aggregate system capacity as a function of radio band, available spectrum, spot beams, waveforms, and payload capability, including antenna size, power, and digital/analog connectivity across various links and availability objectives is described.
Patent
Apparatus and method for efficient handover for low earth orbit (leo) satellite systems
TL;DR: In this article, a set of path factors are determined regarding each of a plurality of communications paths for the mobile user terminal (UT) and a decision is made as to whether to perform a handover of the UT from a first of the communications paths to a second of the communication paths, wherein the determination is based on an evaluation performed based at least in part on the path selection metric (PSM).
Patent
Method for iterative estimation of global parameters
TL;DR: In this article, a method for iterative estimation of a set of unknown channel parameters in a beamforming network including determining a first order estimate of offsets at measurement nodes and an estimate of the confidence in the initial estimate of measurement nodes' offsets is presented.
