I just got 3 pcs. ADXRS453 gyros from Analog Devices ( Farnell price was 100US$ for one piece.)
I added also one ADXRS610 in the picture to compare the size of the gyros. As you can see it can be connected vertical for pitch/roll or horizontal for yaw.This is from data sheet:
±300°/sec angular rate sensing
Ultrahigh vibration rejection: 0.01°/sec/g
Excellent 16°/hour null bias stability
Internal temperature compensation
2000 g powered shock survivability
SPI digital output with 16-bit data-word Low noise and low power 3.3 V to 5 V operation
−40°C to +105°C operation.
Rotation sensing in high vibration environments
Rotation sensing for industrial and instrumentation applications
High performance platform stabilization.
"An advanced, differential, quad sensor design rejects the influence of linear acceleration, enabling the ADXRS453 to offer high accuracy rate sensing in harsh environments where shock and vibration are present.The ADXRS453 uses an internal, continuous self-test architecture."
Specifications like ultrahigh vibration rejection and internal temperature compensation were enough to trigger a flag from 0 to 1 inside my brain. So in less than one month I will have ready one autopilot with XMEGA and this promising gyros.
I will keep you posted about results.
