Get Started¶
Four pages, in order. If you are deciding whether to build one, start with the overview; if you have already decided, go straight to the parts list.
-
What the system measures, how accurate it is, and how a swing becomes a row of numbers.
-
Everything to buy, with links and a cost summary. Some items have long lead times — order first.
-
The sequence and its prerequisites. Doing these out of order means redoing work.
-
Assembled hardware to first shot.
The short version¶
OpenFlight measures a golf shot with two radars and a Raspberry Pi:
- An OPS243-A 24 GHz Doppler radar gives ball speed and club speed from a raw I/Q capture, triggered by a sound sensor that hears the strike.
- A TI IWR6843 60 GHz mmWave radar gives launch angle, launch direction, and club path from the raw radar cube.
- A ballistic simulator turns those into carry.
Shots are streamed to a React UI and, optionally, to GSPro, OpenGolfSim, or another simulator.
Before you commit¶
What this is not
OpenFlight is a working DIY launch monitor, not a commercial product. Expect to solder one joint, flash custom radar firmware, measure your rig's geometry with a tape measure, and read a troubleshooting page or two.
Spin rate in particular is experimental and is not used for carry by default — see rolling buffer and spin detection.
Don't buy K-LD7 radars
The K-LD7 angle radars are deprecated and superseded by the IWR6843. Their software support is retained for existing builds only. See Legacy (K-LD7).
