探访我国首颗能源工程专用卫星制造基地

Core Viewpoint - The launch of China's first energy engineering dedicated satellite, the Electric Power Construction 1 (电建1号), marks a significant advancement in monitoring the quality of major energy projects with millimeter-level precision from space, improving upon traditional ground-based monitoring methods [1][7]. Group 1: Satellite Features - The Electric Power Construction 1 satellite utilizes a flat design, differing from the traditional spherical shape, as there is no air resistance in the vacuum of space [1]. - The satellite's solar panels are made from special materials that enhance light-to-electricity conversion efficiency by over 50% compared to standard photovoltaic panels [1]. - The solar panels are lightweight, with a total weight of just over 400 grams, allowing them to fold down from a width of 4.8 meters to 2.8 meters for easier rocket transport [3]. Group 2: Technical Specifications - The satellite's core module integrates various precision devices, including a propulsion system for trajectory adjustments and a positioning system to maintain accurate orbital paths [5]. - The radar remote sensing capabilities of the satellite allow for all-weather observation, capable of detecting changes as small as 1 millimeter on the ground, which is crucial for monitoring construction projects and natural disaster warnings [7].
