As Ozbusdriver wrote, it is not just aviation that will benefit from SBAS, but many sectors.
So to write that the cost is on aviation to justify is hard to disingenuous.
Also, you have used a figure of $150M - where does that figure come from and how reliable is it, and what does it include when adding up to the $150M?
