Long averaging intervals help prevent false gradient minima hits generated by signal noise. However, this approach reduces the ability of the algorithm to respond to short scale signal fluctuations in space and time. The amount of signal noise depends on the range and time of the day. The gradient method provides variable averaging parameters.
BL-View default settings use 80-m (262-ft) height averaging close to the ground. This interval is gradually increased to 360-m (1181-ft) averaging used at heights above 1500 m (4920 ft).
The selected time averaging interval depends on the signal noise. It varies between 14 minutes during night-time and 52 minutes on a bright, cloudy day.
