International audience A New Generation Infrared Sky Survey (ANGISS) is proposed for the next decade offering performances matching the requests of the new extremely large telescopes such as the E-ELT in order to prepare and follow-up their programmes. This will require the coverage of thousands of square degrees at K ˜ 25 or better, with an angular resolution of ˜ 300 mas and time domain exploration. Set up on the Antarctic Plateau, a NGISS using a relatively modest telescope (2.5 to 4 m) looks particularly attractive. Moreover, an off-axis optical combination is preferred to fully benefit from the exceptional atmospheric properties of the site and to explore the 2.3-4 μ m window in optimal thermal emission conditions.
