The status field indicates a 2D or 3D, when the GPSMAP 198C 

Sounder has collected the necessary data from satellites to calculate 

a fix. The unit then updates the location, date, and time.

You can use the sky view to help determine if any satellites 

are being blocked, and whether you have a current location fix 

(indicated by a 2D, 2D Differential, 3D, or 3D Differential in 

the status field). The sky view shows a bird’s-eye view of the 

position of each satellite relative to the receiver’s last known 

location. The outer circle represents the horizon (north up), the 

inner circle 45º above the horizon, and the center point a position 

directly overhead. You can also set the sky view to a Track up 

configuration, causing the top of the sky view to align along your 

current track heading.

The GPSMAP 198C Sounder is capable of receiving WAAS (Wide 

Area Augmentation System) satellite signals. WAAS is an FAA 

(Federal Aviation Administration) funded project to improve the 

overall accuracy and integrity of the GPS signal for aviation use, 

but land/sea based users can also benefit from this system. At this 

time, the system is still in the development stage and is not fully 

operational. 
There are currently two WAAS satellites that can be received in the 

U.S.A., one over the Atlantic Ocean and one over the Pacific
