Abstract

The Indian Remote Sensing (IRS) P5 spacecraft carried two identical optical payloads (Cartosat-1), each with a different view angle, for acquiring high resolution remote sensing data in stereo mode for the purpose of generation of topographic maps. Information on terrain height derived from these payloads is useful for applications in a number of forms including digital elevation model (DEM) creation, orthoimage, DEM plus thematic data and scientific visualization. Each optical payload features an unobscured, three-mirror anastigmat, design providing high contrast, and wide swath imagery. The mechanical design of the camera structure enabled accurate location of the mirrors while maintaining a very high degree of dimensional stability during launch and in-orbit environment. This paper presents the optical and mechanical design of the camera assembly as well as the alignment and performance optimization carried out in realizing the Cartosat -1 payload.
