Looking for Inertial Navigation Suite

qiuqiuaaa

I want to find a sensor suite for inertial navigation of my ground robot, which means combination of accelerometer and gyro. I only need program. However, most are used on plane. Could someone tell me whether there is a suite like that? Thank you.

Some info at http://www.dimensionengineering.com/accelerometers.htm

Isn't every bump encountered likely to introduce significant errors? I know some people who have these: http://www.amazon.com/Gtech-Performance-Meter-Pro-501/dp/B004JXG008/ref=pd_cp_e_3 and they give erroneous data unless the streets are dead flat and bump-free.

Gyros drift after a while, you may need a magnetic compass for additional heading reference.
