FOR TRACKING PINGERS

SPRINT unit offers power pass-through to aiding sensors, thereby reducing cabling and interfacing complexity.

SPRINT shares the same hardware platform as Lodestar and is a combined AHRS and INS system: running both the AHRS and INS algorithms concurrently allows inertial navigation to start or restart instantaneously on receipt of a position update, as the AHRS seamlessly provides orientation to the INS on start-up, avoiding the lengthy ‘alignment’ period common to RJE is the only one to provide a full range of systems for all other INS systems. Thereafter, the separate AHRS- and INS- modes of acoustic tracking. computed orientations are autonomously monitored as an indi- cation of system health.
