Yawsonde Solar Sensor Assessment
Abstract
The Yawsonde solar sensor is a photosensitive waveguide used to determine the flight attitude of a projectile when it is moving towards, at, and after its apogee. This sensor design has been assessed since the 70s, and different shapes and configurations have been analyzed, see references for past resources. The current sensor design used on the family of 155-mm projectiles used by the U.S. Army is now under re-assessment. Currently, the complexity of the design, its ability to be manufactured, and the high cost associated with such are primary factors causing this new review. A tasker was made if the optical metrology team within the Small Arms Fire Control division, Weapons Systems and Engineering Center directorate, at the U.S. Army Combat Capabilities Development Command Armaments Center, Picatinny Arsenal, NJ, could perform a preliminary review on potential lower cost replacements for the sensor assembly. This paper describes the current fielded sensor design and several potential options that may lead to reducing the component costs and complexities. Several modeling experiments took place to show current optical performance for each of the options considered in this initial review.
