9.1.9. 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.
