-In order to illustrate how to set up a system we document a reference system and how we've set it up. In our reference setup we have placed 3 anchors above and 3 anchors bellow the flight area, shaped in inverse triangles. This allows to get good accuracy in X, Y and Z.
-This is the reference system from which measurement where taken:
+====== Reference set-up using 6 anchors (TWR) ======
+This reference system can be used to position in Two-way ranging mode (TWR). In this reference setup we have placed 3 anchors above and 3 anchors bellow the flight area, shaped in inverse triangles. This allows to get good accuracy in X, Y and Z. There are [[misc:investigations:lps-precision|measurements of accuracy and precision]] for this reference system.

+====== Reference set-up using 8 anchors (TDoA/TWR) ======
+This reference system can be used to position in Two-Way Ranging mode (TWR) and Time Difference of Arrival mode (TDoA). In this reference setup we have placed 4 anchors above and 4 anchors bellow the flight area, shaped like a box. Note the numbering of the anchors, this allows to get good accuracy in X, Y and Z.

-====== Measurements taken from our reference set-up ======
-To validate the system we took a series of measurement from the reference system. You can see the results in the page [[misc:investigations:lps-precision|Measurements of accuracy and precision of the Loco Positioning system]].
