The transportable Quantum Gravimeter QG-1 is designed to determine local gravity to the low nm/s2 level of uncertainty. It relies on the interferometric interrogation of magnetically collimated Bose-Einstein condensates (BEC) in a transportable setup. An atom-chip plays a major role in creating the BEC, allowing high controllability of the atomic cloud. In connection with the absorption detection a better characterization of uncertainties of the motional degrees of freedom is possible. For our current setup, we also discuss methods for operating the gravimeter in seismically noisy environments.
