    With high precision and high space mapping distinguish，Resources will be widely used in the no. 3 of disaster prevention and reduction、Farming, forestry, water conservancy、Ecological environment、Urban planning and construction、Traffic and national defense construction, etc to provide services。

    

    高精度高清晰长寿命 High precision high-definition long life

    总设计师曹海翊：数月的在轨测试显示，资源三号所有性能和功能达到预定目标。图像清晰、层次分明、定位精度高。

    CaoHaiYi chief designer：Months of on-orbit tests showed，3 all resources performance and function to achieve the intended target。Image clear、distinct、Higher precision。

    高精度背后有四个“秘密武器”。一是使用三线阵相机，可以无畸变高稳定地获取立体影像。二是厘米级精密轨道确定技术，双频ＧＰＳ接收机高精度定轨。三是角秒级姿态确定技术，采用国产高精度星敏、国产高精度陀螺，达到高姿态稳定度和高姿态确定精度。四是微秒级星上时间同步技术，采用全新设计的分布式时间系统，配合高精度时间自动校准技术。

    High precision behind it are four“Secret weapon”。One is to use three linear array camera，Can no distortion high stability for stereo images。2 it is the cm-level precision rail determine technology，Double-frequency GPS receiver orbit determination precision。Three levels of second attitude Angle is determine technology，With domestic high precision star sensitive、Domestic high precision gyro，To high-profile stability and high-profile sure accuracy。Four is microsecond star on time synchronization technology，The new design of distributed time system，Cooperate with high precision time automatic calibration technology。

    资源三号使用了四色多光谱相机技术，多光谱影像与全色影像数据融合，实现了民用高分辨率的多光谱数据获取。此外，卫星首次采用高速１０比特量化技术，大大提高了图像清晰度。

    3 the use of resources of four color spectrum camera technology，More images and full-color spectrum image data fusion，Realize the civil high resolution multi-spectrum data acquisition。In addition，For the first time by using high-speed satellite 10 bit quantitative techniques，Greatly improve the image contrast。

    

    “娘子军”的细心与细致 “Women's detachment”The careful and meticulous

    曹海翊：如果说与其他卫星研制团队有什么不同，资源三号卫星研制团队的女性成员比较多。

    CaoHaiYi：If developed with other satellite team what's different，Resources satellite number three development of female members of the team more。

    资源三号测绘卫星的定位精度是现有遥感卫星中要求最高的。女性设计师们把细心、细致、追求完美淋漓尽致地倾注到指标分配、系统设计、过程控制及测试验收等每个环节。

    Resources number three positioning accuracy of surveying and mapping satellite remote sensing satellite is existing in the highest demand。Female designers take care、meticulous、In pursuit of perfect incisively and vividly in filling to index distribution、System design、Process control and test receiving each link。

    以热控设计为例，三线阵相机对透镜温度要求特别高。女主任设计师傅伟纯对每个部件材料的热耗精确计算，在传统热控措施基础上又采用新型热控材料，保证了相机温度的均匀性和稳定性，确保相机成像质量。

    To the thermal control design for example，Three linear array of lens camera particularly high temperature requirements。Female director master wei of each design pure kit materials precise calculation of heat consumption，In traditional thermal control again on the foundation of the thermal control using new materials，Ensure the camera temperature uniformity of and stability，Ensure that camera image quality。

    卫星研制成功的背后，是团队不为人知的艰辛付出。尤其是女同志，既是科研人员，又是妻子、母亲、女儿，承担着工作和家庭的双重责任。

    The successful development of the satellite behind，Is a team unknown great efforts。Especially the female comrade，Is both scientific research personnel，And his wife、mother、daughter，To undertake the work and the family dual responsibility。

    三年来，特别是工程攻坚阶段，她们有的孩子小没人照看，有的孩子中考高考没时间辅导，有的老人病了不能陪床尽孝。她们把太多对家庭的愧疚深埋心底，无数次擦干眼泪后继续投入工作。

    Three years，Especially crucial stage engineering，They have little no one to look after children，Some children to test the college entrance examination didn't have time to coaching，Some old man sick can't stay in the hospital with her filial。They put too much to family buried deep in the heart of the guilty，Countless times wiped away tears on the into work。
