General Description

The Rover Surface Iridium satellite mooring location beacon continuously monitors location for
mobile surface assets and/or instrument moorings. Rover makes use of the bi-directional, global,
real time Iridium Satellite Short Burst Data (SBD) network in combination with GPS position
location. Rover's sleek tubular design and internal dual Iridium/GPS antennas located at each end
cap allow it to be easily retrofitted into a variety of surface mounts. Even surface installations
which capsize may be able to transmit location information.
Inside the Rover is a 9603 Iridium satellite Short Burst Data core radio transceiver, a specialized
low power Xeos digital controller with GPS and Iridium hardware.
Rover is intended for surface deployments and should not be deployed in situations which exceed
100m in depth. Xeos Technologies Inc. (Xeos) manufactures other specific products for either
surface, or subsurface applications to depths of 11,000m.

Theory of Operation

The Rover is intended for providing regular location information on high value assets at the
surface, drifting or moored. After being activated, the Rover is deployed at the surface and begins
sending location messages as per the user settings. The internal battery pack provides over 1500
messages.
Operators can communicate with the surface deployed Rover via Iridium using email commands.
Status information can be obtained, including the health of the GPS system and battery voltage.
Timings are settable, and the default is one message every 3 hours. If you need to make a change
to settings, the Rover will receive the command to change the timing the next time it checks for
messages, as much as 3 hours after the command is sent.
The Rover will continue to send position messages based on the timings, until it is manually
turned off or the battery pack drops below the minimum voltage requirement of 7V.
Due to the location of dual Iridium/GPS antennas at both ends of the enclosure, the Rover will
continue to try and send position messages, even when inverted or capsized.
