Guidance Control Computer for Launch Vehicle

The H-ⅡA/H-ⅡB are the main launch vehicles domestically developed in Japan. With 14 consecutive successful launches among a total of 20 attempts, they have now acquired international reliance and are improving their competitiveness. NEC is involved in this project with the guidance control computer (GCC). As part of development for dealing with component depletion, NEC is developing a new GCC featuring high speed, high performance, compact size and light weight by adopting a new MPU. This paper introduces the circumstances of the development of past computers for launch vehicle together with the features, functions and performance of the new GCC and the efforts NEC will make with regard to computer systems for launch vehicle in the future.

Small SAR Satellite Technology Promotes Dissemination of a Comprehensive Space Utilization System

The needs of synthetic aperture radar (SAR) has recently been increasing. This is because it is an image sensor capable of observing the Earth’s surface regardless of weather or time of the day. Aiming at providing high performance Earth observation services, with the low price and the short delivery term, NEC is developing a small SAR satellite of the 500-kg class by utilizing the SAR system technology, spacecraft design technology and small-sized satellite standardization technology that have been accumulated up to the present. This paper introduces an outline of the small SAR satellite system, the techniques used in its development and the projected global deployment of an Earth observation data service.

Development of the Earth Observation Satellite “DAICHI” (ALOS)

The Advanced land Observation Satellite “DAICHI”(ALOS) is one of the world’s largest class earth observation satellite launched on January 24, 2006. The primary mission of “DAICHI” is obtaining enormous volume of image data for global topographic mapping and emergency disaster monitoring of the disaster-struck area. It has three remote sensing instruments (PRISM, AVNIR-2 and PALSAR) for the precise ground surface observation.This paper describes practical applications of the images obtained via the three remote sensing instruments over the five year period subsequent to the launch and the ways that the obtained data may contribute to the social infrastructures affecting the lives of the people both inside and outside Japan.

Fundamental Space-Supporting Technologies and Their Development Process

NEC’s space technologies are supported by a broad range of fundamental technologies. Production innovation activities have brought space technology from a field of work dependent on the skills and techniques of expert workers to the forefront of production innovation. Space technology is inextricably linked to material development. NEC developed the most advanced reaction-sintered SiC optical mirror material, which makes it possible to manufacture a mirror with light weight and high strength. Meanwhile, spacecraft on-board software technology is being developed to meet the trends of diversification and increased precision of mission requirements. Image processing for more advanced utilization of remote sensing data is a technology that responds directly to the needs of data users. This paper introduces the above fundamental technologies supporting NEC’s space technologies and their development process.
