Understanding Anchor Restriction Setting Parameters
Restrictions Hierarchy
When nothing is set, the calculation is using a global RTLS Server configuration.
When a master anchor is being used for a calculation and it has its custom settings, all values defined in the Master Anchor Restriction settings will override the global configuration in the calculation.
When a neighbor anchor is used in calculation with master specifying special master/neighbor settings (usually only thresholds), the thresholds of the global settings and master's settings are overridden.
Anchor Restriction Setting Parameters Overview
| Parameter | Possible Values | Description | Other |
|---|---|---|---|
Position Data Output | |||
| Store To DB | 0 (No), 1 (Yes) | Whether the positions calculated by this anchors should be stored in database. | |
Position Data Filtering | |||
| Zone Tolerance | <1, 100> | How further away from localization cells are the positions accepted. | |
| Ignore Border Positions | 0 (No), 1 (Yes) | Whether the positions lying near the edge (0-10 cm) of the localization cell are discarded. | The edge of the localization cell is determined by the position of anchors used in current calculation and the zone tolerance. |
Position Adjustment | |||
| Z-Axis Compensation | -1 (Off), <0, 100> | Height of the tags from the ground in meters. When set the calculation is done in 3D. | Helps to make the localization more precise for deployments with big anchor/tag height differences. The height of the anchors must be set. |
Position Calculation Settings | |||
| Mpfit Bestnorm Threshold | <0, 10 000> | The bigger the value the worse positions are accepted. | |
| Optimum Error Threshold | <0, 1 000> | The bigger the value the worse positions are accepted. | |
| Corrected Optimum Error Percentage | <0, 1 000> | The bigger the value the worse positions are accepted. | |
| Max Number Of Computing Anchors | {3, …, 100} | How many anchors may maximally be used for position calculation. | |
| Min Number Of Computing Anchors | {3, …, 100} | How many anchors may minimally be used for position calculation. | |
| Min Number Of Correcting Anchors | {3, …, 100} | When the first calculation fails, the recalculation is done with fewer anchors. Minimal number of these anchors is defined by this value. | |
Anchor Synchronization | |||
| Sync Firstpath Threshold | <-115, -75> | Threshold for synchronization signals. (First Path) | |
| Sync RXPowerLevel Threshold | <-115, -75> | Threshold for synchronization signals. (RX Power Level) | |
| Sync Firstpath Index Threshold | <0, 1 024> | Threshold for synchronization signals. (First Path Index) | |
Tag Blink Raw Filtering | |||
| Blink Firstpath Index Threshold | <0, 1 024> | Threshold for blink signals. (First Path) | |
| Blink Firstpath Threshold | <-115, -75> | Threshold for blink signals. (RX Power Level) | |
| Blink RXPowerLevel Threshold | <-115, -75> | Threshold for blink signals. (First Path Index) | |
