ASSESSMENT OF MODIFICATIONS TO THE EXPERIMENTAL DISTRESS ALERTING AND LOCATING SYSTEM

The report documents a study of modifications required to allow for the use of the experimental Distress Alerting and Locating System (DALS) as a preoperational SAR system. In particular, the following areas are addressed: Multiple access and false alarms in an attempt to prevent system saturation; Automatic deployment techniques for the user device (hand-held unit); Situation coding to describe emergency status of distressed vessel/person; The feasibility of a frequency modification for operation on an allocated safety and distress frequency; Repackaging techniques incorporating a non-destruct antenna, long shelf life batteries and a sealed (environmentally protected) case; and The desirability and feasibility of adding to the distress device an 'on-air' indicator and/or a 'response to your call' indication.
