We present a compact and transportable inertial sensor for
precision sensing of rotations and accelerations. The sensor consists
of a dual atom interferometer operated with laser-cooled 87Rb.
Raman processes are employed to coherently manipulate the matter
waves. We describe and characterize the experimental apparatus. A
method for passing from a compact geometry to an extended
interferometer with three independent atom-light interaction zones is
proposed and investigated. The extended geometry will enhance the
sensitivity by more than two orders of magnitude which is necessary
to achieve sensitivities better than 10-8rad/s/.
