Japanese Earth Resource Satellite 1

NSSDCA/COSPAR ID: 1992-007A

Description

The main purposes of this Japanese Earth Resources Satellite-1 (JERS-1) are to check functions and performance of optical sensors and synthetic aperture radar and to establish an integrated system for observing earth resources. Other objectives include making surveys of Japanese land, monitoring agriculture and forestry, preserving the environment, preventing disaster, and monitoring the coasts. With a box type shape, the JERS-1 has a body approximately 1 by 1.8 by 3.1 meters in size. The solar cell paddle measures 8 by 3.4 meters. A Mission Data Transmitter (MDT) and a Mission Data Recorder (MDR) are equipped on the JERS-1. The spacecraft uses a zero-momentum, strap-down, three-axis control mode for high precision attitude control. Experiments on board the JERS-1 are Synthetic Aperture Radar (SAR) and Optical Sensors (OPS). The SAR is an active microwave imaging sensor achieving high resolution and having capability of operating all day and in all weather. The Optical Sensors are multispectral imaging radiometers with high geometric resolution and having capability of taking stereoscopic image. The minimum lifetime of this mission is two years. The JERS-1 program is a joint development between the Ministry of International Trade and Industry (MITI) and the Science and Technology Agency (STA/National Space Development Agency of Japan (NASDA).
