I'm disappointed that it's at least hard to find how to buy this IMU. No links to suppliers, no prices... Without availability, what's the point in the story about supposedly good system? You don't want to talk here about dancing unicorns unless they're real, do you?
The manufacturer is Northrop Grumman. I have no idea who you are or what your finances are like, but I am willing to bet that you cannot afford to buy it.
It is interesting to consider what the function of this kind of information is. I suspect the real purpose is to give the public warmer feelings when they discover that their local Congress person has received major donations from Northrop Grumman. And they can say “oh that’s the Mars sensor company” instead of thinking of the company’s other products.
