majority of the continental United States and portions of Alaska.
WAAS is just one service provider that adheres to the Minimum
Operational Performance Standard (MOPS) for global Satellite
Based Augmentation Systems (SBAS).
All SBAS systems use the same receiver frequency; therefore, any
operational SBAS system may be capable of providing your GPS
unit with increased accuracy at any location in the world.
Currently, enabling WAAS on your Garmin GPSMAP 580/585 in
regions not supported by ground stations may not improve accuracy,
even when receiving signals from an SBAS satellite.
To enable WAAS, go to GPS tab and press Menu selecting “Enable
WAAS”.
Digital Selective Calling
Digital Selective Calling (DSC). DSC uses marine VHF radio GPS
technology to transmit and receive location information. DSC is
used by mariners to assist them in two major areas: Distress Calls
and Position Reporting.
A non-emergency DSC Position Report allows mariners to exchange
and show their position. When you receive a DSC position, you can
create a waypoint or to show the received position on an electronic
map.
An emergency DSC Distress Call allows a vessel to transmit a
substantial amount of information in a single transmission, or “call,”
without the need for voice communication. When nearby mariners
or rescue teams receive the DSC signal, an alarm sounds, and they
immediately receive the position of the caller.
The mariner or rescue team can navigate (Go To) the caller’s
position or forward the call to the Coast Guard. When the Coast
Guard receives the call, they can immediately access the caller’s
information (such as who they are and the type of vessel) in their
database while they are in transit to the caller’s location.
