Developed by ADS under CNES responsibility in partnership with Eumetsat, IASI-NG payload on board of METOP-SG satellite will deliver data for operational meteorology, climate monitoring, and atmospheric chemistry in the next decades. In order to improve by a factor two compared to IASI the spectral resolution and radiometric error, the instrument is designed around a Mertz compensated interferometer, whose good spectral performances have been checked at subassembly level in 2020. The PFM is now fully integrated and will go through functional tests, performance tests at ambient and in TVAC through 2022. The aim of this paper is to give an overview on these activities.
