How do I describe an XYZ velocity in a written sentence?

500 Views Asked by At

I'm creating a voice interface for Amazon Echo, providing status information regarding the International Space Station (ISS). I'm attempting to express the XYZ velocity of ISS.

Speed inquiry example request and response:

Q: How fast is ISS traveling?

A: ISS is traveling at 27,604 kilometers per hour. That's 17,153 miles per hour.

Of course, speed is different than velocity as speed knows no direction. How would I express the following in a sentence?

x velocity: 7.33 km/s

y velocity: 1.83 km/s

z velocity: -1.3 km/s

Here's my first attempt at it:

ISS is currently traveling at an x velocity of 7.33 kilometers per second, a y velocity of 1.83 kilometers per second and a z velocity of -1.3 kilometers per second. That's a speed of 27,604 kilometers per hour, or 17,153 miles per hour.

What is the more appropriate way to describe XYZ velocity or is this the best way?
