Gyro-stabilization of the Imagenex Model 881A-GS
makes the high resolution 881A sonar into a system capable
of crystal clear visualization of the ocean environment from
moving platforms, no longer compromised by the blurring
effects of host vehicle rotation. An advanced, low drift gyro is
integrated directly into the sonar head, so the sonar can now
compensate for vehicle motion in real time with unprecedented
accuracy, stability, and robustness.
The enhanced capabilities of the 881A-GS have not
compromised the performance of the 881A sonar. On short
range, this sonar scans using a 2 mm range resolution, and
can auto-adjust acoustic frequency and resolution to scan up
to a 200 m radius, 360° surrounding area.
The Model 881A-GS still has low power, simple set-
up, and small size that make it an ideal tool for large work
ROV’s and small inspection vehicles. On it’s own it is now an
amazingly simple drop sonar and borehole inspection
package: just add a laptop computer and power supply and
run the included Imagenex software.
