General Discussion / Re: USB-GPS Working in PilotAware
« on: October 26, 2015, 06:06:20 pm »I have a G-Mouse based on the MTK chipset, and one of the 'recommended' uBlox7 GPS dongles.
The MTK chipped GPS has an almost instantaneous startup, position fix is spot on, as is 'direction'. Whereas the uBlox7 dongle can sometimes take 5 minutes to come up on a cold start and sometimes goes in and out of GPS lock several times before it becomes reliable. It also has a tendency to 'wander' in both position and direction, and often shows a groundspeed (albeit very low) when the thing is just sitting there.
I too have those issues with my uBlox, taking an age to fix from cold, then shows a small amount of movement, only 2 / 3 mph then settles for a bit. None of which I got when using the iPads gps source.
