Lodestar 500 is a combined solid state Attitude and Heading Reference System (AHRS) and optional SPRINT Acoustically Aided Inertial Navigation System (AAINS).
The instrument is comprised of three high grade, highly reliability, commercially available, Ring Laser Gyros (RLG) and accelerometers. The sensors are also the standard for commercial aviation with a proven 15+ year track record.
Lodestar AHRS requires no external aiding and can settle in 5 minutes or less in dynamic conditions. SPRINT INS adds advanced Aided Inertial Navigation that runs concurrently with the Lodestar AHRS algorithm.
This dual algorithm capability is unique in the market and allows for dual use from one inertial instrument, e.g. Lodestar AHRS for ROV, SPRINT INS for Survey.
On-board data storage and backup battery functionality ensures continued operation and no data-loss even if communications or external power is lost.
