9.1.7. Beacons’ jitter codes
In order for the beacon to be able to move between submaps, the service zones
of these submaps must intersect, the intersection area of the service zones of
neighboring submaps forms a handover zone, when the beacon enters the
handover, it becomes possible for it to go to the neighboring submap. This
ensures the positioning of the beacon on the entire area of the map.
Jitter is a code corresponding to a stationary beacon, depending on the code, a
stationary beacon introduces a delay before emission and, accordingly, the
received signal will be delayed by this value, the mobile beacon knows this delay
by the emission cycle number and makes the appropriate distance adjustment.
Jitter codes, sets of ultrasonic frequencies and TDMA makes every submap
unique and let mobile beacon displays in correct submap.
