Satellite multi-purpose instrument GuardianSCL™

speed logcompassfor boat

Know your heading. Understand your movement.
GuardianSCL derives heading from GNSS rather than from a spinning mass, so there is no settling time and no drift to compensate. Heading and satellite speed over ground are presented clearly, and the functions are selected to suit the installation.

GuardianSCL combines GNSS-derived vessel heading and satellite speed-over-ground information to give bridge teams a clearer understanding of orientation and movement. Heading, course and speed describe different aspects of navigation. The selected GuardianSCL configuration can be matched to compatible receiving equipment and vessel integration requirements.
