CAS500 FPA (1) : FPA

CAS500 is a 500kg-weight its scale is in the middle of Application Satellite(e.g. Arirang-satellite) and Nanosat(e.g. scientific satellite), but its spatial resolution is 0.5m level which can provide observation image as precise as Application Satellite. Pushbroom scanning is the way how CAS500’s optical payload can achieve an image by skimming the crust with its optical camera. Developing precise optical structure, system operating manipulation, and also corresponding crust scanning pace with Line-rate is required to maintain MTF performance and achieve high-end image. Line-rate is a pixel shooting pace on a single column of linear CCD imaging detector.

FPA(Focal Plane Assembly) is the heart of optical payload which composed of (1) CCD, (2) Electronic board for CCD control, imaging, process and interface, (3) Housing which stabilized structurally and thermally, and (4) Heat pipe for ventilation. i3system already achieved all kinds of space level technology including CCD control, low-noise imaging, fast imaging process and its interface, structural design for heat, and delivered fine CAS500 FPA to consumers.

-Supply power from Spacecraft Bus(SC BUS) through CEU Power Supplier(CEUP) and input Reference Synchronizing Signal(PPS) and Remote Control Signal(TC) through Camera Controller Box(CCB).

-Transmit Remote Measurement Signal(TM) through Camera Controller Box(CCB).

-Transmit achieved image to Payload Data Transmission Subsystem(PDTS) through Channel Link.

CAS500 FPA (3) : Specifications

LUTI CEM (1)
This is the first lunar probe development project which makes Korea Republic can secure generic technologies that are necessary to developing probe, orbiter, lander, space science payload, and Deep Space Network. Development of testing orbiter which is the first stage of this project goes forward based on international cooperation, and proceed development of key technology of space probe, deep space network, and space science/technology payload. Next step is launching KSLV by developing domestic unmanned lunar probe and lander. Testing lunar probe will contain five kinds of payloads that are domestically developed, and also the other payload that NASA is planning to develop. 5m level of high resolution camera will be installed in testing lunar probe. Also, installing space internet test equipment,  gamma ray spectrometer, lunar magnetic field meter, and polarized light camera which is planned to be developed by domestic researchers. i3system successfully developed 5m level of high resolution camera for lunar orbiter, and delivered to its consumer.
