Episode notes
Remote ID Failure
- Remote ID, intended to identify drones and their pilots, has failed due to prioritizing cost over performance.
- The chosen Bluetooth/Wi-Fi technology has limited range and is ineffective for law enforcement or public use.
ADS-B Overview
- ADS-B improves aircraft tracking accuracy by leveraging GPS, enabling electronic conspicuity.
- This allows aircraft to see each other electronically, enhancing self-separation and potentially preventing mid-air collisions.
Transponder Modes
- Aircraft transponders have evolved from basic identification (Mode A) to altitude reporting (Mode C) and selective interrogation (Mode S).
- ADS-B extends Mode S by automatically transmitting information, enhancing situational awareness.
