Windfinding Using the Loran-C and Omega Long Range Navigational Systems

This paper describes a weather balloon tracking system designed to be both portable and quickly erectable. The purpose of this system is to enable upper air soundings to be made over the oceans from rented space on merchant vessels. The system is based upon the telemetry of existing long range navigational aids for determining relative balloon position and track. Details of instrumentation are given, along with results of flight tests performed in the latter part of 1966.
