A 50 nano-g resolution quartz Vibrating Beam Accelerometer

This paper reports the design, realization and test of a 50 nano-g resolution Vibrating Beam Accelerometer (VBA). Based on the VIA or DIVA quartz vibrating beam accelerometers, dedicated for tactical applications (±100 g measurement range, 300 μg repeatability, all errors combined), this work explores the improvement of the VBA resolution by reducing the measurement range to ±10 g, targeting navigation applications for lower dynamic vehicles.
