Figure 4-1 Sky view clearance
A better sky view clearance helps to achieve better performance. If the 3D
position data is available in advance and the device can be put to ‘Fixed’ mode, a
compromised sky view clearance may not be a serious limitation. But if the 3D
coordinates need to be calculated by the GeckoSynco itself, the clearance should
be the top priority in location selection. As a rule of thumb, there should be no
obstruction to the sky within 60 degrees vertically and horizontally, as depicted in
Figure 4-1. When installed, the satellite info web page can be consulted to verify
that at least 4 satellites are in sight, given by the ‘Num SV’ parameter in Figure
6-6.
