Sandel
SG102 AHRS
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.

Designed as a plug-compatible replacement for the Bendix/King KG 102, the SG102 is ideally suited as an upgrade for existing Bendix/King KCS 55A compass systems. 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.

Offering a superior approach to inertial reference, the Sandel SG102 continues our tradition of innovative, modular solutions that enable you to easily and affordably upgrade your aircraft.

• Certified for primary heading reference
• Solid state, plugcompatible upgrade for the Bendix/King KG102A D.G.
• Compatible with all common directional gyro interfaces
• Pitch and roll output for auxiliary applications requiring stabilization
