Where the old RedSpy had about 10-15 infrared leds, the new tracker has two times as much leds. This ensures our tracking points covering the ceiling are lit up properly and will be captured by the infrared camera inside the tracker. The field of view of the new Stype has also increased, meaning that more tracker points are visible to the system. Partially obscuring the camera isn’t such a big deal anymore. Where before operators had to be careful not to put a part of their body in-between the tracker and the ceiling, now this problem has almost vanished.
Another welcoming change from the old to the new system was the introduction of an ethernet connection between the tracker and base station instead of a fiber optic cable. This change means that the whole tracking system doesn’t rely on a fragile fiber cable, but instead is connected with a robust and easily interchangeable ethernet cable.
