This position retrieved from the most recent ACU poll. This value is expressed in decimal
degrees. ROSS polls the ACU for position on a five 5 second interval.
4.18 Handoff Mode
The ROSS Handoff Mode is defaulted to automatic mode (satellite handoff is triggered by vessel
position within Service Areas) on startup. If Force Manual Mode is invoked, Automatic Handoff
mode is disabled. Automatic Handoff mode can also be enabled or disabled. When Automatic
Handoff mode is disabled, the modem will continue to transmit except if it enters a coordinated
area with a transmit flag set to disabled. On power up Automatic Mode is always enabled.
4.19 Stealth Mode
If enabled, ROSS will omit any location information in the Satellite Location Identification

unidentified from network operators. This mode can be enabled or disabled from the Operations
menu in the ROSS client console.
