The SG102 Attitude Heading Reference System (AHRS) is a solid-state three-axis instrument certified for primary heading reference. Pitch and roll information is also provided for stabilization of other equipment such as weather radar, FLIR cameras, etc. A full set of heading outputs (XYZ, ARINC 429 and RS-232) is also available to allow upgrade of other common directional gyros. Weighing just over two pounds, the SG102 system also includes a Sandel-designed sealed magnetic transducer (magnetometer) for stabilized magnetic heading.

Features

• Certified for primary heading reference
• Compatible with all common directional gyro interfaces
• Pitch and roll output for auxiliary applications requiring stabilization
• >10,000 Hours MTBF, Calculated
• Plug compatible with the KG 102A directional gyro, the SG102 is ideally suited for upgrading existing Bendix/King® KCS 55A compass systems. Multiple heading formats (XYZ, ARINC 429 and RS-232) are also supported to allow upgrading of other directional gyros or interfacing with Sandel’s SN3500 and SN4500 Primary Navigation Displays.

The SG102 system also includes a Sandel-designed solid-state sealed magnetic transducer (magnetometer) for stabilized magnetic heading. Utilizing the latest MEMS sensor technology, the compact SG102 weighs just over two pounds and provides size and weight savings over traditional mechanical gyros.Offering a superior approach to inertial reference, the vibration-resistant SG102 AHRS continues the Sandel tradition of innovative, modular solutions that enhance reliability while saving you time and money.
