Taiwan's launch of FORMOSAT-5, scheduled for this Thursday, will be the first space program in which National Space Organization (NSPO) takes full responsibility for the complete satellite system engineering design including payload(s). 

The mission of the program is shown 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
• To promote the space science experiment and research.

FORMOSAT-5 will operate in a sun synchronous orbit at 720-km altitude with 98.28-degree inclination angle. 

Similar to FORMOSAT-2, an optical Remote Sensing Instrument (RSI), which provides 2-m resolution panchromatic (PAN, black and white) and 4-m resolution multi-spectral (MS, color) images, will be the primary payload on FORMOSAT-5.  The primary payload consists of one PAN band with 12,000 pixels and four MS bands with 6000 pixels each.  In addition, a scientific instrument, Advanced Ionospheric Probe (AIP), has been chosen as the secondary payload.  The National Central University (NCU) is responsible for developing the science payload.  

The FORMOSAT-5 program consists of Space, Ground, and Launch segments. 

The Space segment is made up by: 

• Spacecraft Bus
• Remote Sensing Instrument (RSI)
• Scientific Instrument 

Ground segment includes: 

• TT and C ground station
• X-band antenna system
• remote TT&C station
• satellite operation and control center
• image processing center 

The launch segment includes the Falcon-9 launch vehicle.

As a FORMOSAT-2 follow-on program, the first NSPO self-reliantly designed satellite, FORMOSAT-5, is scheduled to be launched on August 25, 2017 (Taiwan Time) by SpaceX's Falcon 9 from Vandenberg Air Force Base, California, USA. The 450-kg satellite will operate in a two-day revisit Sun-synchronous orbit at 720 km altitude and 98.28 degrees inclination. FORMOSAT-5 will provide two-meter panchromatic and four-meter multi-spectrum images at various processing levels; also offer state-of-the-art ionospheric space science data for the geoscience researches.

Formosat-5 is the first satellite program in which the NSPO was fully responsible for as a system integrator. The mission objectives of FORMOSAT-5 are to:

• build up and demonstrate Taiwan's indigenous space technology on the remote sensing satellite 
• continuously serve the global imagery user's community of FORMOSAT-2 
• promote the advanced space science research domestically 

In addition to indigenous payloads development, NSPO is also responsible for the development of the key spacecraft components, ground control systems, and image processing systems. FORMOSAT-5 is to embark on a five-year observation mission around the globe. FORMOSAT-5's global coverage capability, smart agility feature, and pioneer of using a CMOS sensor for a commercial optical Earth observation satellite will bring even broader research applications to the geoscience community.
