Abstract

Hokkaido Satellite Project was kicked off at April in 2003 by the volunteer group that consists of students, researchers and engineers in order to demonstrate the space business models using nanosatellites of 15kg/50kg in Japan. 
The Hokkaido satellite named “TAIKI” is characterized by a hyperspectral sensor with a VNIR (visible and near infrared range) and a laser communication instrument for data downlink communication. The development of the hyperspectral sensor was started from 2003 and manufactured HSC1.0 and HSC1.5 as the laboratory models. The airborne remote sensing experiment was executed by loading HSC1.5 and inertia measurement unit (IMU), and the ground observation experiment using the hyperspectral sensor and the geometric correction of the sensing data were demonstrated. 
At the next step, we have succeeded to develop a hyperspectral camera as the spin-off product named HSC1700 which installs both the hyperspectral sensor unit and a scanning mechanism inside. The HSC1700 is specified by the spectral range from 400nm to 800nm, 72 spectral bands, image size of 640 x 480 pixels, radiometric resolution of 8 bits and data transfer rate of 30 f/s. After the release of the spin-off product HSC1700 to the general market, many big companies have been keenly interested in and purchased the products. The hyperspectral camera is gradually creating a new market in many fields such as medical area, foods, manufacturing and inspection, and this success attracts the attention of not only mass media but also government. 
At the beginning of 2008 we started to develop a space qualified hyperspectral sensor HSC3000 based on the optical design of HSC1700. Last year we developed the hyperspectral camera HSC1800 funded by New Energy Development Organization (NEDO) as the position of the breadboard model of HSC3000. HSC1800 is specified by the spectral range from 400nm to 1000nm, 81 spectral bands, image size of 640 x 480 pixels, radiometric resolution of 10 bits and data transfer rate of 200 f/s. By averaging outputs of several adjacent pixels to increase S/N, HSC3000 of the space use is targeted at the specification of 50 m spatial resolution, 61 spectral bands, 640 x 480 pixels, 10 nm spectral resolution and S/N300. The main objective of HSC3000 is to develop the fully systemized optical unit for space use. The optical performance of HSC3000 will be comparable to CHRIS developed by ESA but the total budget of development will be reduced to one-fifth.
