Initial estimates of size, mass, power and data rate are presented. Performance characteristics for the instrument and all major subsystems including the optics, focal plane assemblies, onboard calibration, onboard processing and thermal subsystem are presented along with performance predictions for instrument sensitivity and calibration. This paper describes the CI design, including concepts of operation for data collection, calibration (radiometric, spectral and spatial), onboard processing and data transmission to Earth. CI provides contiguous spectral coverage from 380 to 2500 nm at 20 m GIFOV at nadir across 5000+ km2 scenes with spectral sampling, radiometric sensitivity and calibration performance needed to meet the demanding requirements of coastal imaging. In addition, CI measures spectral radiances in the near-infrared and shortwave infrared for atmospheric corrections while also measuring cloud radiances without saturation to enable more accurate removal of instrument stray light effects. These products include water-leaving radiances in the near-ultraviolet, visible and near-infrared for separation of absorbing and scattering coastal water constituents and for calculation of chlorophyll fluorescence. This paper reports on recent design studies for a hyperspectral Coastal Imager (CI - pronounced 'sea') that measures key data products from sun synchronous orbit. Hyperspectral measurements also provide capability for measuring bathymetry and bottom types in optically shallow water and for detailed cross calibration with other instruments in polar and geosynchronous orbit. Resolving the complexity of coastal and estuarine waters requires high spatial resolution, hyperspectral imaging spectroradiometry. This paper details an integrated design method of space-borne remote sensing camera for further reference. Consequently, it successfully passed the qualification level of vibration test and thermal vacuum test. Integrated design result shows, the payload had outstanding characteristics of high rigidity and high stability. As a result, the integrated design makes the less technical difficulties of the design and installation of thermal control structure, higher efficiency of passive thermal dissipation and less on-orbit power waste.

Simultaneously, the full consideration is given on the integration design of camera’s thermal control structure and the satellite structure. The organic unity of the integral work of satellite platform and the payload provides the steady support of the equipment, in addition, the difficulties of camera structure design are reduced remarkably. Considering the engineering practice, a typical structure forming method is given out which is applied to the Geosynchronous remote sensor camera. This Paper presents a space-borne integrated design analysis of remote sensing camera on Geosynchronous orbit.
