AVIATION & AERONAUTIC CALCULATOR
Ads B Coverage
A precise tool.
What is the Ads B Coverage & How does it work?
ADS-B (Automatic Dependent Surveillance – Broadcast) is a surveillance technology used in aviation to track aircraft positions and other information. The coverage radius of an ADS-B antenna depends on its height above ground level.
The relationship between the coverage radius (R) and the antenna height (h) can be approximated by the formula:
R = 3.57 times sqrt{h}
R = Coverage radius in nautical miles
h = Antenna height in feet
h = Antenna height in feet
This formula assumes a flat Earth model and does not account for atmospheric refraction or obstructions.

Frequently Asked Questions
How do I calculate ADS-B coverage radius?
Use the formula R = 3.57 × √h, where R is the coverage radius in nautical miles and h is the antenna height in feet.
What does ADS-B stand for?
ADS-B stands for Automatic Dependent Surveillance – Broadcast, a technology used to track aircraft positions.
What factors affect ADS-B coverage?
The primary factor affecting ADS-B coverage is the antenna height above ground level. Other factors include terrain and atmospheric conditions.
Can I use this formula for all types of aircraft?
This formula provides a basic approximation and may need adjustments for specific aircraft or operational environments.
What is the coverage radius for an ADS-B antenna at 100 feet?
The coverage radius would be approximately 11.8 nautical miles using the given formula.
How does terrain affect ADS-B coverage?
Terrain can obstruct line-of-sight, reducing ADS-B coverage. Higher ground elevations generally improve coverage distance.
Is there a maximum height for ADS-B antennas?
There isn't a strict maximum height, but practical considerations like signal interference and cost typically limit antenna heights.
