I have just bought Globsat BU353S4 GPS-receiver. Now I have a doubt: it is mandatory to mount it in an horizontal position (i.e. facing the sky) or it can be also tilted of some angle with no perceptible loss in precision?
I'm talking about an ideal situation: two antennas with zero obstacles around them. One is mounted horizontally, while the other has some angle with respect to the terrain.
As I know, usually this patch antennas have a ground plane. Maybe that metallic plane can obstruct the view of one or more satellites... but I'm not sure, this is just a personal speculation.
P.S. I'm struggling to mount it on a motorcycle, so there is not a big choice of places where the antenna can be mounted.
