Final step is to check each synchronization from master to neighbor slaves in "Sync Stability" tab.
Synchronization is essential for positioning.
2nd difference shows synchronization stability which is calculated from successive synchronization timestamps sent from master anchor and received by neighbor anchors. Good synchronization is below value 1, while values above 2 indicates more imprecise synchronization and thus anchors are excluded from position calculation by default. The threshold value 2 can be set to more relaxed value if accuracy requirements are less strict, then sub-meter accuracy is not achievable.
When to check the graph?
- After the initialization when you set new masters
Whenever you set a new master
Sync graph shows the stability of the synchronization over the time.
You select master and check appropriate neighbor anchors whether their sync values are below 2. If yes, you can check all masters within the system.
If some anchor is not synchronized below value 2 you will need to check line of sight visibility to master anchor, check whether distance to master anchor is not too big. You can also try to select different master.
- There is a possibility to show only anchors which are close to the master within some radius, furthermore the anchor restrictions might be applied to this view.
- There is also possibility to show strength of the signal RSSI between the master and anchors in range and First Path parameter both in dBM. These values are not related to threshold 2.
Once you finish the work with Sync graph, please click on STOP button, otherwise, it will take processing power of the server.
Finally, after master selection is done we recommend to make a RTLS Studio backup.
