9.2 TDMA Type 2 - Full-overlapping TDMA
The steps below describe how to run IA with TDMA feature, which helps to improve
the tracking quality in complex situations.
Suitable for IA only. Use IA Software
Beacons HW v4.9 should have different frequencies
When you work with two TDMA submaps, update rate reduces twice.
10.1.1. Mount stationary beacons in according to the TDMA chapters in
Placement manual.
10.1.2. Wake up beacons included in Submap0. Enter the values in the table
“distance between beacons”, Freeze it. If necessary, set the shift,
rotation, height, etc. Draw a service zone (More info: Submaps feature
description).
10.1.3. Wake up beacons included in Submap1. If the submap uses beacons
from other submaps, you must add them to the current one. Draw a
service zone, fully crossing with Submap0’s service zone.
10.1.4. If submaps with the same set of frequencies intersect, it is necessary to
use TDMA. (This is the mode of sequential radiation, when for each
stationary beacon the number of the cycle in which it should emit and
the number of cycles of radiation after which these numbers are
repeated is set)
For example, in the room there are beacons 19kHz, 45kHz and two
31kHz and submaps respectively 19kHz+31kHz and 31kHz+45kHz
both include beacon 31kHz, therefore for all beacons the length of the
TDMA sequence is set to 2, while the position in the TDMA sequence
for beacons in 19kHz+31kHz submap is set to 0, and for beacons in
31kHz+45kHz submap is set to 1. As a result, the radiation of beacons
in submaps occurs sequentially, first 19kHz+31kHz submap, then
31kHz+45kHz submap. You can also use absolutely the same set of
frequencies in submaps (Submap0 = 19kHz+31kHz, Submap1 =
