I am in Vancouver, BC and am configured as a SMU but successful PlanePlotter multi-laterations are almost non-existent, usually under ten per day.
Looking at the SharerLocation.gpx file, I see a large gap between Victoria, BC and Portland, OR. Perhaps there are ABS-B data suppliers in that area but no one appears to be providing multi-lateration data, at least not on a consistent basis. If someone in that gap could provide multilat data, PlanePlotter users would have a much greater chance to see the location of aircraft that are not yet equipped with ADS-B. From what I’m seeing, we could possible see fifty percent more aircraft with one of two more multilat data suppliers in that gap.
