Leading edge sensor technology providing accurate and reliable results in harsh marine environments without the need of recalibration.
Sub-surface vehicle operators are faced with a number of operational challenges. Sufficient level of positioning accuracy in GPS deprived underwater environments or the need for re-calibration for each new project, or change of location, are two examples of those challenges.
ION has over 50 years of experience in developing leading edge sensor technology. The 321 Heading Sensor is the industry standard in seismic exploration industry with an installed base of more 70,000 units. The sensor has been used in a wide variety of harsh environments, and at all latitudes, and has been deployed in military, scientific and commercial applications.
ION’s Model 321 heading sensor uses an optical encoder that is magnetically aligned to the earth’s North Pole. Thanks to the unique, patented magnetically coupled optical encoder construction, the 321 sensor is able to provide accurate and reliable measurements without the need for recalibration.
- Accurate, reliable measurements in variety of marine operating conditions
- Unique, magnetically coupled encoder which eliminates the need for re-calibration
- Proven history of 0.5-degree accuracy in many applications
- Installed base of more than 70,000 units worldwide
