In this paper, echo occurrence rates for the Dome C East (DCE) and the new Dome C North (DCN) radars are studied. We report the ionospheric and ground scatter echo occurrence rates for selected periods around equinoxes and solstices in the final part of the solar cycle XXIV. The occurrence maps built in Altitude Adjusted Corrected Geomagnetic latitude and Magnetic Local Time coordinates show peculiar patterns highly variable with season. The comparisons of the radar observations with the International Reference Ionosphere model electron density and with ray tracing simulations allow us to explain the major features of observed patterns in terms of electron density variations. The study shows the great potential of the DCE and DCN radar combination to the Super Dual Auroral Radar Network (SuperDARN) convection mapping in terms of monitoring key regions of the high-latitude ionosphere critical for understanding of the magnetospheric dynamics.

Lessons learned from hosting an Infrared Payload on a communications satellite This paper highlights salient lessons learned from the United States Air Force s (USAF) Commercially Hosted Infrared Program (CHIRP) and discusses how they may apply to future hosted infrared (IR) payloads on geostationary orbit communication satellites (comsat). The primary goal of the CHIRP program is to perform a technological demonstration to advance the Technological Readiness Level (TRL) of staring Wide Field of View (WFOV) IR sensors and associated data processing. Its secondary goal is to show that commercially-hosted ¿rideshares¿ are a viable way to test experimental payloads in general. The primary challenges relate to integrating up-front systems engineering with a particular payload and satellite on a commercial provider s launch schedule and field of view. In particular, we highlight how these observations will affect the analysis of trade-offs when choosing between free-flying and commercially-hosted, staring IR missile warning payloads in the future.
