The GBAR experiment aims at measuring the free fall of antihydrogen atoms in the terrestrial gravitational field. It is located at CERN in the AD area. It is the first experiment which has been connected to the ELENA low energy antiproton ring that started commissioning in the summer of 2018. First tests with antiproton and positron beams were performed in summer and fall of 2018. The status and plans of the experiment are described in this document.
