Steam VR outside-in tracking base stations

Version 1.0 vs 2.0

2.0:  up to 4 lighthouses can be used,
optical sync by swept laser instead of separate area flash.

Version 1.0:  120 degree FoV with up to 2 flat-faced lighthouses;  manual

4.5m max separation in two revisions:

• first with an irregular layout of 15 LEDs
• second with a square 3x3 grid of 9 LEDs

V 1.0 controllers work only with V1.0 lighthouses.

Version 2.0:  two curved face revisions with 150 degree FoV, 5.5m max separation

• built by Valve for Vive Pro, slightly more compact.
  HTC provided power adapter, port for syncing to V1.0, but never developed.
• second built by Valve for Index;  slight appearance but no functional difference.

V2.0 controllers are backward compatible with V1.0 lighthouses.
