SPRINT 500 INS


 
General 
Product Name:SPRINT 500 INS
Product Description:SPRINT INS interfaces to aiding sensors such as USBL, a DVL, pressure sensor and sound speed. Power-pass through to aiding sensors is supported to ease integration. SPRINT INS can be operated without external time synchronisation and aided with manual positions and DVL for relative navigation. SPRINT has a proven track record spanning 10 years in the field in diverse applications from vehicle gyrocompass to demanding applications such as ROV guidance and mid water station keeping. The instrument is available in 4,000 and 6,000 metre depth ratings and is one of the smallest form factor subsea inertial instruments available.
