The 2685 Mobile Integrated Positioning System (MIPS) is an advanced Ultra Short Baseline (USBL) underwater tracking system. The MIPS antenna provides a subsea positioning solution in a compact design for use in a naval environment.
System integration is via a high speed serial link ideal for OEM applications. The MIPS antenna is deployed from a single point mooring, allowing a variety of platforms to be utilised.
Accuracy is based on the correct speed of sound being entered, no ray bending and an acceptable S/N ratio.
