VTI Technologies has introduced a MEMS-based gyro-accelerometer sensor which combines a 3-axis accelerometer with a near tactical grade 1-axis gyro in the one package.
The new sensor product family is based on VTI's proprietary 3D-MEMS-manufacturing (micro-electro-mechanical-system) technology which is said is "stable and low noise".
The first members of the gyro-combo product family are SCC1300-D02 (±100 º/s x-axis & ±2 g 3axis) and SCC1300-D04 (±300 º/s x-axis & ±6 g 3-axis). Stand alone gyro components will follow in 2010.
All angular rate sensors feature outstanding insensitivity to shocks and vibrations. The sensors are temperature compensated over whole operating range of -40°C to +125°C. Bias stability (Allan variance) for the gyroscope is below 2 °/h and bias accuracy over full temperature range <±0.6 º/s.
There are separate digital SPI-interfaces for gyro and accelerometer.

Target applications include Inertial Measurement Units (IMUs), platform control and stabilisation, motion analysis and control, as well as guidance- and navigation systems.
Dimensions for the lead frame based package are 18.65 mm x 8.5 mm x 4.53 mm (length x width x height)
Samples of the SCC1300-D02 and D04 are available immediately with volume production in 1H 2010.
