Open publisher page 0 citations

Abstract

A compass module accessory was developed and combined with the XYLON standard BAR-350 digital barograph to meet the OSTIV requirements for a barograph with combined altitude and compass heading records. A small magnetic compass was optically encoded to provide a digital output. The microprocessor in the BAR-350 barograph was used to interrogate the compass and process the output to provide a compass heading printout or indication of circling. Several flights were made to demonstrate the operation and show the type of records produced.
