COAA PlanePlotter 6.7.5.1 Review – Radar-Grade Tracking at Home
The virtual radar that reveals hidden aircraft.
COAA PlanePlotter 6.7.5.1 plots aircraft that FlightRadar24 misses. See if it’s right for you.
Introduction
Your ADS‑B receiver hums along, painting airliners on FlightRadar24. But the C‑17 doing circuits overhead? Missing. That military Learjet on Mode‑S only? Invisible. The screen shows silence where your ear hears engines.
That gap is real. So many aircraft carry Mode‑S transponders but never embed position data. Commercial platforms filter them out as noise. And you’re left wondering what just flew past.
According to EUROCONTROL, roughly 30% of all IFR flights in European airspace rely on Mode‑S without ADS‑B position reporting. That’s thousands of flights daily that you can hear but can’t see unless you have the right decoding software.
Overview
COAA PlanePlotter is a Windows virtual radar application that receives raw aircraft data and plots it on user‑calibrated maps. Created by Bev Ewen‑Smith under the COAA banner, the software first appeared in the early 2000s and has evolved through continuous updates 6.7.5.1 being the current mid‑2026 release.
Its core purpose is simple: show the aircraft that web‑based trackers either cannot see or choose not to display. By connecting receivers like SBS‑1/3, RadarBox, or an RTL‑SDR dongle running dump1090, PlanePlotter decodes Mode‑S, ACARS, HFDL, and more.

Description
PlanePlotter 6.7.5.1 takes raw message streams from your receiver—whether a hardware box or a network feed from dump1090—and extracts hex codes, altitude, speed, heading, and, if present, position coordinates. The software then plots these data points onto chart images that you calibrate yourself.
The real magic sits in two positioning engines. Multilateration (Mlat) timestamps the arrival of a single Mode‑S transmission at multiple ground stations. The server computes time‑difference‑of‑arrival hyperbolic intersections, requiring at least four receivers to generate a fix. The PlanePlotter sharing network, with over 6,000 active contributors, produces more than 200,000 Mlat position fixes on a typical day aircraft that would otherwise stay invisible.

Key Features
Multilateration for Position‑Less Aircraft
Mlat computes real‑time coordinates for Mode‑S aircraft that never broadcast their location. By combining time‑of‑arrival data from several sharers, the server triangulates a fix. During an afternoon monitoring the North Sea, Mlat revealed a pair of RAF Typhoons refuelling from a tanker aircraft that never appeared on any web tracker. Coverage depends on ground‑station density; urban regions fare best.
ACARS, HFDL, and VDL2 Decoding
Beyond Mode‑S, PlanePlotter decodes airliner ACARS messages, oceanic HFDL traffic, and VDL2. While decoding a transatlantic A350’s feed, fuel reports and waypoint positions appeared in the log and plotted automatically. No secondary decoder app required.
Alerting Engine
The alert system triggers on squawk codes, registrations, altitude bands, or custom rules. Notifications can pop on screen, send email, or fire SMS via prepaid credits, making it useful for photographers chasing rare registrations.

FAQ
Is PlanePlotter hard to set up compared to Virtual Radar Server?
The interface isn’t polished; it reflects two decades of feature accumulation. Basic ADS‑B plotting works quickly, but Mlat, Beamfinder, and HFDL require reading the wiki and forum posts. VRS looks nicer, but it can’t do multilateration or Beamfinder.
Can PlanePlotter really show military aircraft that aren’t on FlightRadar24?
Most military transports and fighters broadcast Mode‑S without position. If four or more ground stations receive the same signal, Mlat calculates a fix. So yes, you’ll see movements that commercial sites filter out especially in areas with good sharer coverage.
What receiver do I actually need to get started?
You can run PlanePlotter in download‑only mode using data from the sharing network—no receiver necessary. To contribute locally, a cheap RTL‑SDR dongle with dump1090 works fine. Dedicated boxes like the Kinetic SBS‑3 offer better sensitivity but cost considerably more.
