This could be critical for real-time applications. The data validity is instantaneous, since they are used as soon as they are received to compute the current position (and moving will invalidate them). The time scale allows us to derive a -bound in the sensor sampling period. Sampling as frequently as the +bound in the sensor sampling period. Sampling as frequently as this (lower) bound is equivalent to keeping the sensor always on.

The figures show how the sampling strategy is able to keep the variance of the estimation bounded, while reducing the on time. -- GitLab
