Indian Nano Satellite-1C (INS-1C)

4.Indian Nano Satellite-1C (INS-1C): As per the ISRO officials, a miniature multi-spectral technology demonstration (MMX-TD) camera on-board INS-1C is sending high-resolution images of Earth.

• About INS-1C: It carries Miniature Multispectral Technology Demonstration (MMX-TD) Payload from Space Applications Centre (SAC).
• PSLV-C40 Mission: Placed INS-1C in orbit on January, 2018, 3rd satellite in the Indian Nano Satellite (INS) series.
• Origami Optics: Built on the multi-fold reflective optics concept, reducing thickness compared to conventional cameras.
• Applications: Data can be used for topographical mapping, vegetation monitoring, aerosol scattering, and cloud studies.
• Orbit & Imaging: Provides RGB images covering 29m × 29m area with 23m ground sampling, operates from a 505 km polar sun-synchronous orbit.
• Technology & Development: Developed by ISRO’s Space Applications Centre under the Robust Technology Development Programme, uses metal mirrors instead of conventional glass-based lenses, enhancing spectral coverage.
