Odin是一颗兼具天文学和高层大气使命的卫星。它被设计用于观察从地面上无法观察到的物种，特别是水和氧气。主要仪器是辐射计，工作频率范围为486-581千兆赫和118.75千兆赫。它的双反射镜望远镜有一个1.1米的主要和前端放大器冷却最大的灵敏度。一个三轴稳定系统提供了一个指向精度优于1000。奥丁是代表瑞典，加拿大，法国和芬兰的空间机构开发的，并于2001年2月发射到太阳同步圆轨道。奥丁科学小组由来自伙伴国家的天文学家和航天工作者组成，已建立了观测方案，并负责与奥丁项目有关的所有科学事项。航天器和仪器运行良好，预计在两年的标称寿命之后仍将继续运行。
Odin is a satellite with a combined astronomy and aeronomy mission. It is designed for observations of species dicult or impossible to observe from ground, especially water and oxygen. The main instrument is a radiometer, operating in the frequency range 486-581 GHz and at 118.75 GHz. Its double-reflector telescope has a 1.1 m primary and the front-end amplifiers are cooled for maximum sensitivity. A 3-axis-stabilisation system provides a pointing accuracy better than 10 00 .O din was developed on behalf of the space agencies in Sweden, Canada, France and Finland and was launched into a sun synchronous circular orbit in February 2001. The Odin Science Team, composed of astronomers and aeronomers from the partner countries, has established the observing programme and is responsible for all scientific matters regarding the Odin project. The spacecraft and instruments are performing well and operations are expected to continue well beyond the nominal two-year lifetime.
