Map building
Before building a map, you need to determine the need to use jitter and if it is necessary
to select a mode, the modes differ in information capacity and transmission speed, i.e. for
how many cycles the jitter code is transmitted:
-
Jitter Mode1
- information capacity = 6 bits, and transmitted in 2 cycles.
-
Jitter Mode2
- 8 bits, 4 cycles.
-
Jitter Mode3
- 4 bits, 8 cycles.
The beacon movement introduces distortions in the definition of jitter code, therefore for
objects moving fast, the most suitable mode is 1. So using 5 frequencies you can build 10
unique sub-maps in a set of frequencies, without using jitter, if this number is insufficient
or not in the presence of a complete set of frequencies or you cannot use them because
of the requirement of uniqueness of neighboring sub-maps, use jitter.
For example, when using
Jitter Mode1
and only two codes 0 and 1 for each stationary
beacon, from 10 initial combinations, you can get 40 submaps, because each submap
contains two beacons and, accordingly, 4 combinations, however this number may turn
out to be slightly less when one stationary beacon enters into more than one submap,
because the number of combinations is reduced. You can select a mode in the
Dashboard menu.
You also need to select
Jitter granularity
, each ms is 0.343m i.e. 3ms corresponds to
1.03m, which is enough for most cases.
You also need to select the
Jitter area
, this parameter indicates the neighborhood
around the jitter value, which is considered a valid deviation of the jitter value, if this
deviation is exceeded, the accepted jitter value is considered incorrect and does not take
part in determining the submap.
Select and set the
Code of jitter
in the menu of the emitting beacon
