Underwater EM Sensing
E-field Sensing Buoy
QFS has created a sophisticated underwater E-field sensing buoy called the “Aphros” system. Aphros is based on our proprietary underwater electrodes, which offer long lasting performance that doesn't degrade with wet/dry cycling. Aphros's robust, user-friendly configuration simplifies operations while its technological advances deliver advanced performance.
The system offers the following advantages:
- Compact sensors that can fit into an A-size sonobuoy package
- E-field sensor noise floor of less than 1 nV/rtHz above 1 Hz
- Large effective aperture along vertical axis
- Robust "dry" electrodes
- Low power requirements
- Low cost
Seabottom Based Receiver
QFS has developed a new class of electric and magnetic field sensors and integrated them with the high performance electronics and data storage systems to create the QMax EM3 ocean-bottom electromagnetic receiver. This innovative, compact receiver is designed to optimize operational efficiencies and produce the highest quality data possible for processing and analysis.
