1090 ADS-B

[SMO]

I just installed a GTX 330D ES, replacing the standard 330 and adding the additional antenna. All is properly configured for ADS-B out. I have made a couple local flights with this - most of which are at about 1000' AGL. I am in a mountainous part of BC, Canada. I have gotten the PAPR report from Nav Canada which says all the ADS-B parameters have passed, however when I look on Flightaware I see much of my flight is missing. Flightaware just draws some straight lines from the last point it picked up to the next point it picks up, even though my flight took a different route to that next point.

Does anyone have any insight into why the PAPR report would fully pass but it seems some of the flight's data points are missing on Flightaware? I do understand that the missing points could be because I was shielded from the satellites due to the local terrain, but then why would the PAPR say it was 100%?

Nav Canada has access to the Aireon satellite data. To my knowledge Flightaware does not. They primarily rely on their network of feeders with ADS-B receivers, as well as some data feeds from the FAA. Not sure if they have any feeds from Nav Canada. The low altitude flight won't give you much chance for a feeder to pick up your signal (unless they happen to be very close to you).

Ok, that makes sense. Looking into this a bit more I see that Flightaware has a subscription based product that includes the Aireon data, but is quite expensive. Doesn't look like there is any free service using this data.

Do you, or anyone, know if I would need to jump through any other hoops to legally fly in controlled airspace in the U.S.?

This might be a shot in the dark.. I had a similar lack of FlightAware coverage. Example: blank portions of a flight in areas where previously had full coverage. Turned out the stubby belly antenna was loose
