11.5. 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:
-
Real Time Player in the Dashboard (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 off the Real-Time Player (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) -> Enter 0 value
