Typical Technical Specifications:

Introduction

The Overlap deployer Model 214 was developed for

the German Helios A&B satellites. This motorized

mechanism is capable of extending and retracting a 60

foot (18.3 meter) long Tubular Extendible Element (TEE).

The deployer features electrical stops at full-extend and

–retraction. A potentiometer, driven by the moving

element, provides a continuous indication of deployed

length. This deployment mechanism design will meet the

requirements of document MIL-A-083577B (USAF)

General Specification for Moving Mechanical

Assemblies for Space and Launch Vehicles.
