There are several key parameters in any real-time locating system (RTLS) or indoor positioning system (IPS). Among them:
There are many more, and you can learn about them in detail: https://www.youtube.com/watch?v=zg3oW_U_jdY&t=3949s. Let’s discuss deeper the two of them more:
Notice that location update rate and latency are usually linked but are not the same. For example, simultaneously, you may have a high update rate and high latency.
Also, remember that the accuracy of position measurements doesn’t depend on the location update rate. At the same time, if your system can tolerate more latency in the position measurements, it is possible to achieve higher accuracy of measurements.

Typical update rate with default settings with average-sized submap of 10-15m – 8Hz. We support up to 30-40 Hz for very small submaps of 2-3m. For larger maps of 30m and default settings – 6Hz or so.
There is a clear trade-off between latency and accuracy of tracking. By applying more filtering or averaging, it is possible to achieve better tracking quality, but latency will suffer. Thus, each case must choose between accuracy/quality and latency.
