Abstract

An engineering design of an imager upgrade is under consideration for the GOES-N/Q series. The upgrade consist of adding up to three new IR channels at 4 km resolution and doubling the earth coverage rate. The design approach introduces advanced technology as needed to minimize impacts to the sensor optical and mechanical configuration, electronics box layout, data communication links and ground systems. By operating presently redundant portions of detector arrays and developing double rate signal processors, the scanning servo system and electronics modules are largely retained. Bicolor detectors and optical coatings are used to add channels while retaining the present relay optics and radiant cooler layouts. Lossy data compression of visible imagery and lossless data compression of IR imagery are used to preserve the sensor data and precessed data relay communications links. System NEDT and SNR performance and implementation issues for new technologies are addressed.
