There are several key parameters in any real-time locating system (RTLS) or indoor positioning system (IPS), or indoor navigation system (INS), which are just different names for the same thing. Among the key parameters:
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 though location update rate and latency are usually linked, they are not the same thing. For example, you may have a high update rate and high latency simultaneously.
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. See more: Does accuracy depend on the location update rate?
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.
