  Archeops is a balloon--borne experiment widely inspired by the Planck
satellite and by its High Frequency Instrument (HFI). It is mainly dedicated to
measure the Cosmic Microwave Background (CMB) temperature anisotropies at high
angular resolution (about 12 arcminutes) over a large fraction of the sky
(around 30 %) in the millimetre and submillimetre range at 143, 217, 353 and
545 GHz. Further, the Archeops 353 GHz channel consists of three pairs of
polarized sensitive bolometers designed to detect the polarized diffuse
emission of Galactic dust. We present in this paper the update of the
instrumental setup as well as the inflight performance for the last Archeops
flight campaign in February 2002 from Kiruna (Sweden). We also describe the
processing and analysis of the Archeops time ordered data for that campaign
which lead to the measurement of the CMB anisotropies power spectrum in the
multipole range l=10-700 (Benoit et al. 2003a, Tristram et al. 2005) and to the
first measurement of the dust polarized emission at large angular scales and
its polarized. We present maps of 30 % of the sky of the Galactic emission,
including the Galactic plane, in the four Archeops channels at 143, 217, 353
and 545 GHz and maps of the CMB anisotropies at 143 and 217 GHz. These are the
firstever available sub--degree resolution maps in the millimetre and
submillimetre range of the large angular-scales Galactic dust diffuse emission
and CMB temperature anisotropies respectively.
