Light-pulsed atomic interferometers provide a promising quantum-based solution for inertial navigation applications. In this paper, we present an atomic interferometric inertial sensor designed to simultaneously measure rotation rate and acceleration, through continuous sampling using dual 87 Rb atomic beams as matter-wave sources. We observe Raman-Ramsey and Raman-Mach-Zehnder interferences and validate the inertial sensing capability by comparing the results with a classical quartz accelerometer and an optical-fiber gyroscope. Our work can serve as a foundational element for the development of a fully quantum inertial measurement unit characterized with a high data rate and large bandwidth.
