Garmin 520 Owner's Manual

The Wide Area Augmentation System (WAAS) capability 

produces a more accurate position fix. When enabled 

(GPS set to Normal and WAAS set to Enabled through 

the System Setup Page, also the interface must be set 

to something other than RTCM mode), this feature 

searches for WAAS satellites near your location and 

then receives data for correcting differentials in the 

GPS satellite signals. WAAS satellite numbers begin 

at number 33 and are displayed on the Satellite Page. 

When differential correction data has been received for 

GPS satellites (numbers 32 or below), a D displays in 

the signal bar beneath the skyview. It is helpful to orient 

the unit antenna toward the WAAS satellite shown in the 

skyview. To learn more about the WAAS System, refer to 

the Federal Aviation Administration Web site (

). 

Because the Rino 520/530 relies on satellite signals to 

provide you with navigational guidance, the unit’s view 

of the sky determines how fast you achieve navigational 

status. GPS signals do not travel through heavy objects 

or people: For best results, keep the unit in clear view of 

the sky.

At least three satellite signals are needed to determine 

your location, otherwise the unit displays a “Poor 

Satellite Reception” message with four options:
Use with GPS Off—Select this option if you want to turn 

GPS off.
