What is the difference between Compatt 6 and Compatt 6+?

Both Compatt 6 and 6+ share the same address range and same Wideband 2 ranging protocols, which are proven to offer accurate ranging to better than ±7.5 mm. They can both operate the Wideband 2 telemetry commands used by Fusion 1 and Ranger 2. This allows backwards compatibility and the ability to be used in shared LBL arrays. The major difference is that Compatt 6+, when used with Fusion 2, will operate using new Wideband 3 commands which combines ranging and telemetry for faster operations.
