can be inside but then the design needs to be different to work that way, external GPS generally need to be kept away from the main unit, away from the cameras etcYeah it is my understanding that the GPS puck /mouse antennas you want as far from the camera / main unit as possible, but sure some dashcam brands have the antenna in the mount and about as close to the unit as you can get.
Wish you'd specified that. "GPS interference" is a totally different animal than some random selectromagnetic interference (EMI) happening only within the system.that's what I was referring to previously although my comments were general in nature, not saying it's the problem in this particular case, it's very common with some models of Ducati and BMW though
Pretty much, the "puck" type antenna has a more or less hemispherical pattern. Thus the recommendation to mount it horizontally, so it has the most gain toward the sky (where the sats are at).I am thinking maybe the puck / mouse antenna are more omni directional, another system i am testing ( the SG9663DR ) the GPS antenna are meant to be put on the dashboard, reverse of what i have been used to for many years.
But ever the provocateur i have put the antenna on my windscreen and so upside down, and to be honest GPS fix are just as fast / good as any other camera i have ever worked with.
Wondering about this too. The GPS antenna for my Viofo A129 Duo is right up against the windshield, and in fact forms part of the mount for the front camera (and main system unit).Yeah it is my understanding that the GPS puck /mouse antennas you want as far from the camera / main unit as possible, but sure some dashcam brands have the antenna in the mount and about as close to the unit as you can get.
I do not know if the different approach also entail some "secret" sauce for the brands that do the GPS in mount, i am currently testing a GPS build into the camera system, and by the looks of it the antenna part are just there on the skywards side of the plastic housing, and there dont appear to be any shielding in between it and the other components ( 2 camera units and the main PCB ) only on the PCB itself do you find a EMI shield covering just the SOC as i recall or maybe the SOC + WIFI chip.
