WatchMate
AIS
CPA Closest point of approach in nautical miles. The nearest a target will
come to your vessel if both maintain their course and speed.
TCPA Time until closest point of approach will occur (minutes and seconds).
BRG Bearing from your vessel in degrees magnetic, true or relative.
RNG Range from your vessel in nautical miles.
SOG Speed over ground in knots.
COG Course over ground in degrees true or magnetic.
HDG Heading in degrees true or magnetic.
ROT Rate of turn shown as direction and degrees per minute.
IMO International ship registration number.
MMSI Radio identifier. Used to call vessels via DSC radios.
AIS data is received at various intervals. As a result, you will see the MMSI
number instead of the ship's name until more data has arrived.
Alarm Types
Guard alarm - based on each a target's current distance from your vessel.
CPA alarm - there are four settings associated with CPA alarms: CPA alarm distance,
time until CPA (TCPA), target speed and your vessel speed. The CPA alarm distance
indicates which targets may trigger the alarm. The other settings suppress alarms
if the TCPA is too great, or either vessel's speed is too slow. Help for these, and all
other settings, is displayed on each setup screen.
Muting Alarms
Alarms are muted for each individual target. All other targets remain active.
Profiles
Alarm and filter settings are grouped into four profiles (anchored, harbour, coastal,
offshore). You can change the settings for each profile and switch between profiles
at any time. Select the current profile from the main menu.
Filters
You may filter targets which are moving slower than a specified speed or farther
away than a specified range. Use setup to establish filters for the current profile.
Setup
To change alarm and filter settings associated with a profile, you must select the
profile prior to entering setup mode. Setup mode is accessed from the main menu.
