4 3 FORMOSAT-5 Mission Overview FORMOSAT-5 is the first space program that National Space Organization (NSPO) takes full responsibility for the complete satellite system development. Mission objectives of the program are as follows: To build up Taiwan's self-reliant space technology on the remote sensing payload and spacecraft bus, To develop the key components of the EO-type remote sensing instrument and spacecraft bus by integrating the domestic resources, To continue to serve the global imagery users' community of FORMOSAT-2, and To promote the space science experiment & research. FORMOSAT-5 will operate in a sun synchronous orbit at 720- km altitude with degree inclination angle. Similar to FORMOSAT-2, an optical Remote Sensing Instrument (RSI), which provides 2-m resolution panchromatic (PAN, black & white) and 4-m resolution multi-spectral (MS, color) images, will be the primary payload on FORMOSAT-5. The RSI is composed of Telescope and Electrical Unit. The Telescope consists of Optics, Structure Module and CMOS typed Focal Plane Assembly. RSI, has been jointly developed by NARL's centers including NSPO, ITRC and CIC, as well as domestic organizations of NCSIST, AIDC, CMOS Sensor Inc., and Camels Vision Technologies. In addition, Advanced Ionospheric Probe (AIP) is provided by Institute of Space Science, National Central University for the FORMOSAT-5 satellite as a science payload. The AIP is an all-in-one plasma sensor to measure ionospheric plasma concentrations, velocities, and temperatures over a wide range of spatial scales. The transient and long-term variations of ionospheric plasma can be monitored as seismic precursors associated with earthquakes.

11 FORMOSAT-5 Launch Campaign 10 Satellite Operations S-band TT&C station/ X-band receiving station (National Cheng-Kung University, Tainan, Taiwan) S-band TT&C station (National Central University, Chungli, Taiwan) X-band receiving station (NSPO, Hsinchu, Taiwan) S-band TT&C station/ X-band receiving station (Svalbard, Norway) Satellite Operations Control Center (NSPO, Hsinchu, Taiwan) Image Processing System (NSPO, Hsinchu, Taiwan)

12 11 Image Processing Image Processing System includes five subsystems. The main functions of the five subsystems are described as follows. PSS: To generate a sequence of imaging parameters, such as attitude and timeline, as well as to send commands from ground stations. DIS: To receive X-band signals in real time and to de-compress, de-cipher and deformat into raw remote sensing image data for DPS. DMS: To manage all data storage and flow of IPS, and to provide the services of query, quick look, product order and product packing. DPS: To process raw satellite image data to generate three different levels of image products, Level 1A, Level 1C or Level 2, through radiometric correction or radiometric/geometric corrections. IQS: To monitor and track the qualities of satellite image, such as relative and absolute radiometric corrections, as well as geometric correction. Satellite Tasking Functions Multi-Tasking Stereo Imaging Along Coast Along Longitude
