There are several key parameters in any realtime 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:
Obviously, there 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:
Notice that though location update rate and latency are usually linked, they really not the same thing. You may have a high update rate and high latency at the same time, for example.
Also, remember that the accuracy of position measurements doesn’t really 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.
