Direct interface to a standalone Chelton Control Display Unit (CDU) . Analog/Digital Switched Pins

Better than 5° RMS (highly dependent on quality of placement and proper airframe bonding). Step 1: Mechanical Installation and Airframe Mounting

Capable of COSPAS-SARSAT and Marine DSC decoding.

A typical installation for the 935-2, such as those performed on Airbus AS365 or EC155 helicopters , involves a multi-stage approach including mechanical provisions and avionics integration.

: Monitors six channels in parallel (one tunable receiver plus five dedicated distress guard receivers).

“Now the ugly part,” Leo said to the cat.

The is a sophisticated, tactical direction-finding (DF) antenna system designed for high-accuracy localization of personnel in distress, particularly in Search and Rescue (SAR) and Combat Search and Rescue (CSAR) operations. As part of the reputable 935 Series , this unit provides essential, real-time bearing data for both bus-controlled and stand-alone setups.

For technicians and installers, finding the precise manual is crucial for mounting, wiring, and calibrating this sensitive equipment. This article covers the essential installation phases, technical requirements, and how to acquire the necessary documentation. 1. Overview of the Chelton 935 Series Tactical DF System

Before beginning any physical work, use this checklist to ensure you are fully prepared:

. It must be mounted rigidly and in line with the airframe, either in a normal or inverted attitude. Control Interface

I should also consider possible mistakes users might make during installation. For example, incorrect transducer installation leading to inaccurate readings, or power supply connections not being grounded properly. Including those in the troubleshooting section would be helpful.

The unit features an anti-rotation mechanism to prevent damage during installation and to maintain precise alignment with the aircraft’s longitudinal axis. Avionics and Interface

Before modifying the airframe, verify that your electrical and space provisions match the system parameters.
