Having spent a long night calibrating Ubisense, here is a checklist to make it faster next time. This is with version 2.0.4 of the software. Many thanks to our resident surveying expert Yukang for staying very late to help me out with this.
Doublecheck offsets to apply to surveyed points. Get signs right. Remember which points were surveyed with the reflector pointing up or down, take into account the height of the totalstation.
Take into account the height of the antenna inside the tag. This may add 1-2 centimetres to the height of surveyed points.
Check that the antenna boards inside the sensors haven’t come loose. If they have you need to open the case and clip them back into place.
Check that the sensors are horizontal, roll should be zero.
Optimal pitch of the sensors is 45 degrees downwards. I seem to not point them down enough so should try to emphasise this in future.
