We study the impact of noise on the Planck Low Frequency Instrument (LFI) observations (Mandolesi et al. ) and describe a simple method for removing striping effects from the maps for a number of different scanning strategies. A configuration with an angle between telescope optical axis and spin-axis just less than 90° (namely ) shows good destriping efficiency for all receivers in the focal plane, with residual noise degradation . In this configuration, the full sky coverage can be achieved for each channel separately with a 5° spin-axis precession to maintain a constant solar aspect angle.
