India-based Neutrino Observatory (INO) is a proposed underground facility in the southern part of India. The project envisage the construction of an underground laboratory with a large cavern of dimensions 132m X 26m X 20m to house a 50 kton magnetized iron tracking calorimeter detector (ICAL) to study atmospheric neutrinos. In addition, two smaller caverns will also be constructed to host other experiments. There will be at least 1.2 km rock overburden in all directions. INO-ICAL detector will have a modular structure of total lateral size 48m X 16m and will consist of a stack of 150 horizontal layers of 5.6 cm thick magnetized iron plates interleaved with 4 cm gaps to house the active detector layers. The active detector elements are resistive plate chambers (RPCs), made up of a pair of 3mm thick glass plates of area 2m X 2m , separated by 2mm spacers. The main physics goals of INO-ICAL detector are: (i) Accurate determination of the atmospheric parameters. (ii)Determination of neutrino mass hierarchy. (iii)Resolve the octant ambiguity. (iv) Non-standard interactions, CPT violation, long range forces, ultra high energy muon fluxes. The present status of the project and the progress made so far will be discussed.
