TMC consists of three cameras for fore, nadir andaft viewing in order to obtain a stereoscopic viewof the lunar surface. It will image the lunar surfacein push broom mode in panchromatic spectralregion between 0.5 and 0.85 um. The fore andaft view angle is 25degree with respect to nadir. Itis expected to provide a spatial resolution of 5mand a swath coverage of 20 km from a nominalaltitude of 100 km. The illumination conditions onthe Moon vary significantly, therefore there is aprovision of adjustable gain and integration timesto improve the signal to noise. It requires solar illumination for optimumperformance and the observation period of twoyears therefore, is divided into several imaging seasons,depending on the solar aspect angle
