SPRINT 700 is a combined solid state Attitude and Heading Reference System (AHRS) and 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.
The AHRS requires no external aiding and can settle in 5 minutes or less in dynamic conditions. INS adds advanced Aided Inertial Navigation that runs concurrently with the AHRS algorithm.
This dual algorithm capability is unique in the market and allows for dual use from one inertial instrument, e.g. AHRS for ROV, 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.
