Distributed Sensor Fusion of Ground and Air Nodes Using Vision and Radar Modalities for Tracking Multirotor Small Uncrewed Air Systems and Birds

High-density airspace operations with multiple aircraft type and potentially noncooperative aircraft require distributed sensor detection and tracking systems to monitor airspace for safe, autonomous flight operations for advanced air mobility, urban air mobility, and high density small uncrewed air systems (SUAS) flight concepts. This work collected data using a distributed radar and camera sensor framework during the NASA Advanced Air Mobility High Density Vertiplex project SUAS flight operation. Node locations include on an onboard SUAS, affixed to the Landing and Impact Research Facility with approximate 200ft elevation, on a tripod on first-floor roof with an approximate elevation of 20 ft, and on a tripod on a concrete pad that is approximately 4 ft above sea level. Each node includes camera, radar, and GPS.

Glacial Climate Intervention: A Research Vision

Glaciological research should be expanded to include the science of ice-sheet preservation to determine if engineered interventions applied to critical ice-sheet regions may reduce sea-level rise. This document represents a white paper that articulates a perspective on future research directions based on discussions of glacial climate intervention held at workshops at the University of Chicago (2–3 October 2023) and Stanford University (8–9 December 2023), and at an American Geophysical Union town hall (12 December 2023). Opinions expressed here are those of the authors only and do not necessarily reflect opinions held by all attendees of the workshops and town hall.
