2Select GPS Status.
The following messages are displayed while the GPS receiver is tracking satellites:
“Locating GPS Satellites”: Blackbird searches the sky looking for GPS satellites.
“Acquiring GPS Signal”: Blackbird acquires positioning information transmitted from 1 to 3 tracked satellites while search- ing for more satellites (minimum 4 needed).
“Fixing GPS Position”: Blackbird requires continuous signals from 4 or more tracked satellites (for 30 seconds) in order to accurately fix your position.
“Temporary Poor GPS Coverage”:
Thunderstorms, dense foliage or surround- ing tall buildings may cause temporary loss of position fix (acceptable if under 30 sec- onds).
“Poor GPS Signal, Lost Position Fix”:
You may have entered an area where con- sistently poor GPS signal (lasting 30 sec- onds or more) makes it impossible to maintain a position fix.
“No Line of Sight, Lost GPS Tracking”:
You are in an area where line of sight to GPS satellites has been blocked.
