Understanding ADS-B: How Aircraft Surveillance Works Without Radar
A technical overview of Automatic Dependent Surveillance–Broadcast, covering the 1090 MHz signal structure, decoding pipeline and how Sparrow Global's receiver achieves high sensitivity in challenging RF environments.
Read ArticleUnderstanding AIS: The Global Maritime Tracking Standard
A technical overview of the Automatic Identification System — covering VHF channels, TDMA protocol, message types, Class A vs B transponders, range characteristics, and integration with maritime domain awareness systems.
Read ArticleADS-B Receiver Site Selection: Maximising Coverage and Sensitivity
A practical engineering guide to ADS-B ground station siting — radio horizon geometry, antenna height trade-offs, LNA placement, cable loss, and suppression of LTE, FM broadcast and DME interference for maximum range.
Read ArticleProtecting the Maritime EEZ: A Multi-Layer Surveillance Architecture
How shore-based AIS, coastal surface search radar, satellite AIS and spaceborne SAR can be layered into a fused common operational picture to achieve persistent, wide-area maritime domain awareness across an Exclusive Economic Zone.
Read ArticleUsing Mode S and ADS-B to Filter Primary Radar Targets
A technical look at how cooperative Mode S and ADS-B data is fused with primary air defence radar to classify tracks as White, Grey or Black — reducing operator workload and sharpening the non-cooperative residual picture.
Read ArticleADS-B for Roads: What if Every Vehicle Broadcast Its Position?
A speculative engineering look at applying cooperative surveillance — the principles behind ADS-B and Mode S — to land transport. The technology case, the challenges, the benefits, and the question society will have to answer.
