When talking about space science and about placing a satellite in a specific orbit, this is common.
The orbit of a satellite determines how fast it will rotate around the Earth and what things it will be able to see on the Earth while it's orbiting. A satellite with a circular geosynchronous orbit rotates around the Earth in a circle with a 42,164 km radius. If it's a kilometer up or down then it won't be in proper orbit.
Space scientists will often talk about spacecraft placing into specific orbits, where they reach the correct orbit to do whatever it is the spacecraft is supposed to do.
