# Number of Calculation Anchors

# Position Calculation Settings

The RTLS Studio has got a default setting regarding minimum and maximum number of anchors used for position calculation. In some cases to optimize the RTLS System performance, the number of Computing and correction anchors could be changed.

## Max Number of Computing Anchors

Defines a maximum number of anchors used for position calculation.

In practice, tag usually has unobstructed vision to 4-6 anchors, others are non-line-of-sight which might worsen the results. Therefore, **the default value is 6**. If there is a good signal from more than 6 anchors, RTLS Server tries to select the best six anchors (in terms of signal, synchronization, geometry, etc.) to calculate the position.

If there is more then 6 anchors set up for computing, it consumes more CPU and time without higher benefit.

## Min Number of Computing Anchors

Defines a minimum number of anchors used for position calculation.

Mathematically, minimum is 3, however 4th anchor adds redundancy and ability to calculate the error of computation. **The default is 4.**

## Min Number of Correcting Anchors

Defines a minimum number of anchors used for recalculation of the position. **The default is 4.**
