Two WAAS satellites have been taken offline and two news added.
The impact of this is that most likely your WAAS
GPS will require an upgrade to process WAAS. And until you do... you are losing the benefit of the super accurate WAAS fix.
Look for
GPS providers whose devices supported WAAS to be offering firmware upgrades in the future.
For now... take a step back and be advised that your GPS is no long as accurate as it was.
