Performance Gen 3: 140° physical field-of-view reference. Polar plot uses zenith at center and horizon at edge.
Camera FOV values calibrate the live antenna mask. Projection now uses a 3D camera basis and perspective rays; defaults remain approximate and vary by phone/camera.
Center = zenith/straight up (0° zenith angle). Outer edge = horizon (90°). North is up, East right, South down and West left. Obstructions are positioned from measured azimuth and zenith angle.
Captured images include the camera frame plus survey HUD, reticle, azimuth/elevation, GPS and timestamp. Images remain on this device unless you save/share them.
