TL;DR: In this paper, a method for transporting payload to the outer space features use of the carrier aircraft containing carried aircraft system mode, where the payload is loaded in the carried aircraft and carried aircraft is carried by a carrier aircraft to high altitude.
Abstract: A method for transporting payload to the outer space features use of the carrier aircraft containing carried aircraft system mode. The payload is loaded in the carried aircraft and the carried aircraft is carried by the carrier aircraft to high altitude, where the carried aircraft is launched to transport the said payload to the outer space. Its advantages include high transport efficiency and very low cost.

TL;DR: A new waveform for UAV payload communication in the C-band is proposed and its performance results are shown.
Abstract: Currently, LTE mobile communication technology is considered as the main communication link of UAV. However, an auxiliary communication link is indispensable for stable operation and mission execution of UAV even in areas where existing mobile communication networks can not cover. For stable operation of UAV, auxiliary communication link requires greater communication coverage and link availability than existing LTE mobile communication network. In that sense, it is difficult to use for the auxiliary communication link unlicensed band where there is the small power limitation and severe interference is suffered. Therefore, C-bands, which is allocated for UAV control and payload communication, could be good candidate. In this paper, we propose a new waveform for UAV payload communication in the C-band and show its performance results.

TL;DR: This paper focuses on advanced, cost effective, modular high data rate Data Handling System with many advanced features like DWT based Slice Redundant Compression system, On Board Radiometric Correction, Variable Integration time for payloads, configurable formatter, selectable compression ratio, programmable NUC coefficients for different TDI stages and SPI protocol for communication between different subsystems of BDH system.
Abstract: Baseband Data Handling (BDH) system is one of the major subsystems in the Payload data downlink chain in all the remote sensing satellite missions. Its main functionality is to collect payload data, align data, compress the same and organize as space packets, multiplex these space packets into transfer frames that can be stored or downlinked for further transmission. Furthermore, encryption and channel coding are performed at the downlink chain. As the resolution of payload increases, data volume and number of ports from payloads increase drastically. To handle this high data rate, a modular and scalable architecture is required which focuses on realization cost and realization time. This paper focuses on advanced, cost effective, modular high data rate Data Handling System with many advanced features like DWT based Slice Redundant Compression system, On Board Radiometric Correction, Variable Integration time for payloads, configurable formatter, selectable compression ratio, programmable NUC coefficients for different TDI stages and SPI protocol for communication between different subsystems of BDH system. At present, this system is flown in a High Resolution Remote Sensing Satellite and providing excellent services. Same system will be reused for future missions.

TL;DR: The first occultation mission in the Korean space program, KOMPSAT-5, is scheduled for launch in 2010 and the characteristics of its occultation payload are described in this paper.
Abstract: The first occultation mission in the Korean space program, KOMPSAT-5, is scheduled for launch in 2010. KOMPSAT-5 will have a dual frequency GPS receiver to generate precision orbit determination data and occultation data. The KOMPSAT-5 spacecraft and the characteristics of its occultation payload are described in this paper. An occultation processing system developed by KASI is also introduced.
