Aerial Surveillance Grid (ASG)

Overview

The Aerial Surveillance Grid is a widely used term across countries and planets for an extensive airborne monitoring network. It integrates sensors on rooftops, relay nodes, Scarab-type transmitters, and fixed reception points to maintain continuous mapping of movements over urban areas and open skies

Structure and Operation

The grid consists of urban pillars, perimeter stations, and portable scanning units mounted on patrol vehicles or ground teams. Data streams converge at regional nodes and are forwarded, in summarized form, to central command systems for analysis

Signals and Alerts

Detections are classified into three levels: cold for routine movement, warm for unusual patterns, and hot for anomalous traces. Hot alerts may trigger automated escalation procedures

Data and Access

Regular operators receive near real-time imagery with a delay of a few ticki. Full analytical streams may include historical correlations and trajectory reconstruction. Summarized results can be displayed on municipal dashboards

Detection Methods

The ASG uses passive rooftop captures, reflections off walls and roofs, noise variations from propulsion engines, and thermal residues. Specialized algorithms detect low-profile craft that pull air rather than push it, creating characteristic anomalies

Weaknesses and Limitations

Covered arcades and underground passages create blind spots. Rock walls in canyons may produce false echoes. Intense urban lighting can hide small craft for brief periods. Relay nodes are vulnerable to overload from excessive alert traffic

Role in the Story

The ASG can record anomalies such as unknown aerial traces over city squares or weak pulses over isolated areas, often without confirmed identification
