AAE Pyxis INS + USBL (Model 3690)

The Industry’s First Integrated MEMS INS and USBL Positioning System

Product Overview 

The Applied Acoustic Engineering (AAE) Pyxis INS + USBL represents the pinnacle of AAE's acoustic tracking technology. By permanently embedding a survey-grade Inertial Navigation System (INS) directly into the USBL transceiver head, Pyxis eliminates the need for traditional, time-consuming vessel calibrations.

This "factory-calibrated" approach tightly couples the acoustic transceiver with an SBG Systems Navsight Apogee INS. Because the alignment between the acoustic elements and the motion sensors is fixed at the factory, the system can be deployed on any vessel of opportunity and begin providing survey-grade data (up to 0.1% of slant range accuracy) within minutes.

Why Choose the Pyxis System?

• Calibration-Free Mobilization: Saves an average of one full day per mobilization by eliminating the need for seabed beacon "box-ins" and complex offset measurements.
• Integrated SBG Navsight Apogee INS: Features a high-performance, ITAR-free MEMS INS that provides superior roll, pitch, and heave compensation, as well as a 0.025° GNSS-based heading.
• Sigma 2 Digital Protocols: Utilizes bi-directional wideband signals for maximum range stability and resistance to multipath interference, essential for shallow-water or high-noise environments.
• Superior Accuracy: Delivers up to 0.1% of slant range accuracy (with the directional transceiver), making it suitable for the most demanding subsea construction and inspection tasks.
• Portable & ITAR-Free: The system is designed for global deployment without export restrictions, and a range-restricted version (995m) is available to further simplify international shipping.
