Teledyne TSS Launches AHRS and INS Systems

After two years of development Teledyne TSS debuted its new family of advanced AHRS (attitude and heading reference system) and INS (inertial navigation and attitude and heading reference systems) at Oceanology International.

The Saturn family of products uses fiberoptic technology and incorporates advanced digital signal processing and algorithm design. The company said all units are compact and lightweight in both air and water.

As the first installment of the new product line Teledyne developed four versions of the Saturn family with two basic grades of accuracy available in both surface and subsea configurations. The Saturn 10 has a heading accuracy of 0.1 degrees sec. lat. RMS with a pitch/ roll accuracy of 0.01 degrees. Saturn 30 has a heading accuracy of 0.3 degrees sec. lat. RMS with a pitch/roll accuracy of 0.2 degrees. Both have heave accuracy at five percent or five cm (about 1.97 inches). Both subsea versions use titanium casings rated to 4000 meters (about 13127 feet).

The Saturn 10 systems are designed to support the offshore construction ROV surface navigation and multibeam survey sectors. The Saturn 30 systems are designed as a solid-state attitude and heading reference system (AHRS) for primary surface and subsea navigation.
