陸地探測一號01組衛星為《國家民用空間基礎設施長期發展計畫(2015-2025年)》中的科研衛星,由A、B兩顆衛星組成。
2022年1月26日7時44分,我國在酒泉衛星發射中心,使用長徵四號丙運載火箭,成功發射陸地偵測一號01組A星。
2022年2月27日7時44分,我國在酒泉衛星發射中心,使用長徵四號丙運載火箭,成功發射陸地偵測一號01組B星。
2023年,兩顆衛星完成在軌測試,狀態良好,性能滿足衛星工程研發總要求及應用系統需求,具備投入使用條件。
衛星投入使用後,將緊密圍繞地質、國土、減災、測繪、地震、林草等行業開展服務,可提供地質行業高分辨率業務化形變監測服務,面向國土行業地表分類和地物識別進行業務化拓展,針對測繪進行數位正射影像業務化拓展,服務國家重大災害緊急應變、國家重大地震災害、林草森林資源監測等。
後期,衛星將逐步拓展國外數據應用推廣,服務共建「一帶一路」倡議。

陸地探測一號01組星以雙星繞飛模式,拍攝了全國多雲多雨區以及部分國際多雲多雨區,以雙星跟飛模式,拍攝了國內典型形變區。
製作了各類圖件372幅,生成了全國正射影像、部分多雲多雨區的數位表面模型、典型形變區的形變場產品以及各類應急和林草監測產品。
具體包括甘肅舟曲泥石流、陝西安康地區土石流、北京等地土地利用分類、雲南等地數位表面模式、四川瀘定地震、內蒙古礦難、海南省森林/非森林分佈等。
