Reducing location update latency
Exact latency depends on many factors:
-
IA or NIA
-
From modem or from the beacon
-
IMU sensor fusion or regular ultrasonic only
-
Radio profile
-
Realized update rate
-
Any sort averaging or Real-time player enabled or not
The range is:
~ 12ms for data from a mobile beacon via USB with IMU fusion enabled and not
averaging at all
~ 150ms with 30m-submap and update rate in ultrasonic of 7Hz and not averaging
~ 2 seconds with the same settings as in (b), but Real-Time Player with settings 16, i.e. it
takes into account up to 16 previous readings before giving out the new one
What affects delay:
-
(For
NIA
)
-
Real Time Player in hedge
(For
IA
)
-
Window of averaging and Distance filter settings in modem (For
NIA
)
-
Prefiltration coefficient and Ultrasonic filtering settings in hedge (For
IA
)
How to decrease latency:
-
Turn
(works for
IA
and
NIA)
-
Change the
Window of averaging and Distance filter
settings value to 0 (
For
NIA)
:
-
Choose
Modem -> Window of averaging
(in the right tab)
-> Enter 0 value
-
Choose
Modem -> Distance filter
(in the right tab)
