What is the correct positioning of an external GPS Antenna?
I don't know if the locus community is the right place for a question like this, but I think that gps-devices and gps-software are somehow linked themes.
Here the story: I just bought the well-know (and cheap) Globalsat BU-353S4 (i.e. the one with the sensitive SiRF Star IV chipset), something like the one in the attached photo. I plan to use it with my Samsung 7" tablet with android 4.4.
Doubt: "where I should mount the receiver on my motorcycle? In what position?"
By googling I found fragment of info fighting against the real life...
1. Your receiver should face-up the sky!
But I see people mounting it even on the lateral window of the car. In a vertical position!
So seems that the horizontal placement is not mandatory... or not?
I will not go to paradise when mounting the antenna in angled position???
2. Avoid position with objects obstructing the clear view of the sky!
But, again, people are mounting/placing the antenna just over the dashboard of the car, below the windscreen.The roof of the auto is not covering a huge portion of the sky???
3. Big objects close to the antenna can reflect the GPS-signal causing multi-path signals reaching the receiver!
But, again, what about the metal part close to the antenna inside a car? Lateral frame and the roof are not reflecting the GPS signal?
4. Keep the antenna away from radio interference!
Well, inside an auto there is a lot of electronic stuff, Bluetooth devices and... the smartphone of the driver. But seems that the receivers works the same... or not?
I'm quite confused... my plan is to mount the receiver behind the windshield made of poly-carbonate, but... is the plastic stuff an "obstructing" material?Why the glass of the car windscreen is not obstructing the GPS signals?
