Batteries & Chargers
The ISA500 underwater AUV & ROV Altimeter & Echosounder provides exceptionally long range measurement capability – in excess of 120 meters.
In addition to providing exceptionally long range capability, the sensor has a 1mm accuracy – allowing precision underwater distance measurements to be made.
Optionally, the ISA500 can also be provided with an integrated Attitude and Heading Reference System (AHRS). This provides highly stable Heading, Pitch and Roll readings.
Another optional capability is ECHOGRAM, providing sonar backscatter data for each ping.
Altitude & Echo Sounding
The ISA500 utilises sonar technology to derive distance measurement.
Operating by default at 500kHz, the sensor utilises a broadband composite transducer and electronics together with an advanced digital acoustic engine. The combination of these enable the sensor to achieve long range and high accuracy.
The sensor can be operated at any frequency from 400 to 600kHz – ideal for different applications or operating in conjunction with other hydro-acoustic or sonar equipment.
The ISA500 provides a single range measurement per ping (for use as an underwater Altimeter). With ECHOGRAM enabled the ISA500 can provide sonar backscatter data (for use as an Echosounder).
Optionally available on the ISA500 is an integrated Attitude & Heading Reference System (AHRS) providing Heading, Pitch & Roll.
The AHRS is based on Micro-Electrical-Mechanical-System (MEMS) based technology.
Within the ISA500 there are three MEMS based Gyros, Accelerometers & Magnetometers. The outputs from each of these MEMS devices are fused together, providing highly stable Heading, Pitch & Roll.
The Heading is highly resilient against temporary magnetic interferes. This is aided by a soft and hard iron calibration feature once the unit has been installed on the ROV, AUV or other underwater application.
Provides Altitude readings from 120 meters above the seabed. Also provides Heading, Pitch & Roll. Can emulate any other device – making integration into any ROV or AUV very easy.Reduce the equipment required to provide Altitude, Heading, Pitch & Roll by using a single ISA500 unit.
Distance Measurement
Measure distance to a target underwater. Using the multi-echo capability, measure the distance to and between multiple targets.Measure distance to a target underwater. Using the multi-echo capability, measure the distance to and between multiple targets.
The ISA500 is available in 1,000, 6,000 & 11,000 meter rated housing configurations. Housings are offered in either Titanium or Acetal.
Both forward looking and right angle housing configurations are available – enabling simple integration into any underwater vehicle, towed asset or structure.
An OEM version of the ISA500 is also available, which offers an un-housed version of the ISA500 for integration into a third party housing or system. Alternative connector options are also available upon request.
