Avionics
- Certified for primary heading reference
- Solid state, plugcompatible upgrade for the Bendix/King KG102A directional gyro
- Compatible with all common directional gyro interfaces
- Pitch and roll output for auxiliary applications requiring stabilization
Plug compatible with the KG 102A directional gyro, the SG102 is ideally suited for upgrading existing Bendix/King(r) 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 also outputs attitude information that can be used for stabilization of radar antennas or remote cameras.
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 SG102 AHRS continues the Sandel tradition of innovative, modular solutions that enhance reliability while saving you time and money.
