The Effelsberg-Bonn HI Survey (EBHIS) is a 21-cm line survey covering the HI distribution of Milky Way and of external galaxies up to a redshift of $z\leq 0.07$ in parallel. This is feasible by using state-of-the-art FPGA spectrometers offering more than 16.000 Spectral channels distributed across a 100 MHz band. During the coming six years we will survey the whole northern sky. EBHIS is optimised to reach towards the entire Sloan-Digital-Sky-Survey area a sensitivity comparable to the Arecibo ALFALFA survey. Towards the Milky Way sky EBHIS will be at least twice as sensitive as the Leiden-Dwingeloo

Survey but with a factor 20 higher angular esolution. High speed data recording will allow us for the very first time to apply sophisticated Radio

Frequency Interference mitigation strategies. Targeted observations and multiple coverages of the whole sky will warrant early scientific results which will be timely available for the scientific community. We present the major scientific aims of the survey project as well as early results from the 1500 square degrees which have been already observed during the past winter term.
