may be limited by your geographic location in relation to those satellites, now in developmental service. 
WAAS satellite signal reception requires an absolute clear view of the sky and works best when there are 
no nearby obstructions such as buildings, mountains, etc. WAAS satellites will be numbered 33 or higher 
when viewing the sky view on your GPSMAP 2006/2010. Initial reception of the WAAS signal may take 
up to 15-20 minutes each day, then 1-2 minutes afterwards. When WAAS differential correction has been 
received for GPS satellites (numbers 32 or below), ‘2D or 3D Differential’ will appear in the receiver status. 
To learn more about the WAAS system, its satellite positions and current state of development, visit the 
FAA web site (http://gps.faa.gov). 

Receiver status is indicated at the top fi eld of the page, with the current Accuracy, Dilution Of Precision 

(DOP) and, if equipped with an optional Differential Beacon receiver, Beacon SNR (Signal Noise Ratio) 
above the sky view. DOP is an indication of satellite geometry quality measured on a scale of one to 
ten (lowest numbers the best, highest numbers the poorest). Accuracy uses DOP and other factors to 
calculate horizontal position accuracy in feet or meters. The status fi eld will show one of the following 
conditions:

•   Waiting for GPS Antenna— the GPS receiver is looking for and collecting data from satellites visible 

at its last known or initialized position, but has not collected enough data to calculate a fi x or a 
GPS receiver is not connected.

•   Ready (2D)— at least three satellites with good geometry have been acquired and a 2 dimensional 

position fi x (latitude and longitude) is being calculated. ‘2D Differential’ will appear when you are 
receiving DGPS corrections in 2D mode.

 •  Ready (3D)— at least four satellites with good geometry have been acquired and your position is 

now being calculated in latitude, longitude and altitude. ‘3D Differential’ will appear when you are 
receiving DGPS corrections in 3D mode.

•   Lost Position from GPS Antenna— the GPS receiver is no longer tracking enough satellites for a 2D 

or 3D fi x or connection has been lost between the GPS receiver and the 2006/2010.

•   Simulating— the 2006/2010 is in simulator mode.
•   GPS Antenna is Simulating— the 2006/2010 is receiving simulated NMEA input information.
