任务简介
俄罗斯Resurs-DK 1（46KS）卫星主要用于对地球自然资源研究、生态与紧急情况、海面状态、冰情、地球极地气象条件等信息进行成像和传输，并支持地面用户之间的数字数据交换。为完成这一地球表面观测任务，卫星持续朝向地球定向。该航天器由萨马拉的TsSKB Progress公司建造，基于军用Yantar-4KS1M（Neman）成像卫星。卫星的主传感器是Geoton-L1光电推扫成像仪。在360公里高度处的全色分辨率为0.9米，在604公里高度处为1.5米。多光谱分辨率在1.5至2米之间。

The Russian Resurs-DK 1 (46KS) satellite is mainly designed to image and transmit data on information for Earth natural resources study, data on ecology and emergency, sea surface status, ice situation, meteorological conditions in Earth polar regions, as well as to support digital data exchange between ground users. The satellite is continuously oriented towards the Earth in order to fulfill this program of Earth surface observation. The spacecraft was built by TsSKB Progress in Samara. It is based on the military Yantar-4KS1M (Neman) imaging satellite. The main sensor of the spacecraft is the Geoton-L1 optoelectronic push-broom imager. Panchromatic resolution at an altitude of 360 km is 0.9 m, at an altitude of 604 km it is 1.5 m. Multispectral resolution is between 1.5 and 2 m.
