Wu Flight Lab - PX4 EKF adapter
Upstream: https://github.com/PX4/PX4-Autopilot/tree/v1.15.4
Version: v1.15.4
Commit: 99c40407ffd7ac184e2d7b4b293f36f10fe561ef
Compiler: Emscripten 3.1.64, -O2, no fast-math
Core C++ source: unmodified upstream EKF, matrix, geo, world_magnetic_model.
Enabled: GNSS position/velocity/yaw, barometer.
Browser adapter: synthetic FRD IMU, NED internals, EN horizontal display.
Platform shims: monotonic simulation clock, constants, POD aid-source message fields; no uORB runtime.
IMU 200 Hz, filter 100 Hz, GNSS/barometer 10 Hz, max delay buffer 900 ms.
Initial stationary preflight: 12 seconds, completed before experiment t=0.
Initial WebAssembly linear memory: 16 MiB; maximum 32 MiB per worker.
Simulation and EKF execute on the visitor device. Server serves static assets.
This is a planar synthetic sensor experiment, not PX4 SITL or a flight safety validation tool.
