velocity

Hello all, I am working with a college team to build a (hopefully) hypersonic rocket (M5+). Our goal is to go fast, so we need to be able to prove it. What are some ways we can measure velocity at these speeds? We’re tossing around ideas of building a ‘Rayleigh’ pitot tube, and/or using the...

I need to be able to precisely measure a high-powered rocket's velocity after motor burnout. There is an onboard altimeter, as well as an accelerometer available to me. Which would yield a more accurate result? Also, any recommendations for implementing this with a real time system? If I...
