Another member of the China Resources-1 satellite family has the ability of wide vision, perspective and night vision

Beijing, December 26 (China News Service) -- On December 26, the Resource No. 1 family welcomed its ninth member, the Resource No. 1 06 satellite (also known as the 5-meter optical satellite 02 star or the Resource No. 1 02E star). As a new force, the birth of the 5-meter optical satellite 02 satellite relies on the mature technical foundation of the Resource-1 family to serve the monitoring needs of natural resources in the new era.

The 5-meter optical satellite 02 satellite is developed by the Fifth Academy of China Aerospace Science and Technology Corporation, and the design life of the satellite is 8 years. The star fully inherits the development basis of the 5-meter optical satellite 01 star, and the whole star is equipped with a visible near-infrared camera and a hyperspectral camera, and a new long-wave infrared camera is added to realize the observation of the earth throughout the day.

Wide-sighted: Seeing a city at a glance

The visible near-infrared camera configured by the 5-meter optical satellite 02 satellite has been optimized and upgraded on the basis of the 5-meter optical satellite 01 satellite, with a resolution of 2.5 meters in panchromatic and 10 meters in multispectral light, which can identify the near-infrared wavelength between visible light and infrared, and distinguish the shape, scale size and part of the color of the monitoring target.

In addition, this "eye" will automatically adjust the optimal imaging line of sight, and see the mountains and lakes with a radius of more than 100 kilometers. With the help of sunlight, this camera can keenly capture the changes in monitoring targets, achieve one-time full coverage of large and medium-sized cities, distinguish between various types of land use, and accurately present the size of various land use scales after long-term application, providing support for land use planning.

Perspective: All the information in the ground is known

Considering the monitoring needs of minerals and mining areas, the 5-meter optical satellite 02 satellite uses a hyperspectral camera with 166 spectral bands, which has the ability to identify and classify features. The camera can fully cover visible light, near infrared and infrared, and subdivided into 166 spectral channels, a shot can obtain 166 photos of different spectrum segments, accurately capture the light information reflected by various types of features, through inversion calculations to calculate the content and coverage of the monitoring target, after synthesis is a veritable "treasure map".

Night Vision: Activities are in full swing throughout the day

The long-wave infrared camera is the third "eye" added by the development team to the 5-meter optical satellite 02 star, making the star a "night walker" that can also work in the dark. The satellite's infrared camera is capable of presenting thermal infrared images of the ground, leaving production activity invisible under its monitoring.

The three cameras on the 5-meter optical satellite 02 satellite give it the ability of "wide vision, perspective, and night vision". At the same time, the development team also created a flexible "good body" for the satellite by upgrading the platform performance. The satellite adopts a three-axis stable control mode of ground orientation, has the ability to yaw calibration, greatly improves the attitude maneuverability, and can quickly adjust the attitude for emergency monitoring needs, aiming at the target "raise the camera, say shoot and shoot".

With the successful launch of the 5-meter optical satellite 02 satellite, The network operation of China's medium-resolution optical remote sensing satellite has taken a step forward, serving land resources management, mineral resources exploration, geological disaster early warning, water quality monitoring and other fields, providing assistance for China's economic and social development.
