Advances in Telemetry Capability as Demonstrated on an Affordable Precision Mortar

Abstract

This paper presents three telemetry techniques demonstrated on an affordable precision mortar that allowed the guidance, navigation, and control (GNC) system to be effectively analyzed. The first is a technique for the real-time integration and extraction of GPS data into a sensor telemetry stream. The second is a method for increasing telemetry bandwidth by saving a short period of high rate data and then broadcasting it over the rest of the flight test. Lastly, I present an on-board data storage implementation using a MicroSD card.
