Examples
-
The space probe was designed to measure changes in its orbit period as it approached the black hole.

Charles F. Gammie (University of Illinois), who has studied this question most carefully, has shown that, roughly speaking, fragmentation happens when the gas can radiate away most of its energy in about half an orbit period or less.
Academic text (2005) -
The satellite completes its mission by maintaining a stable orbit period of 90 minutes around the Earth.

Morphology
The meaning 'time required to complete one full revolution' is directly derivable from combining 'orbit' (the curved path of an object) with 'period' (a measured interval). This straightforward noun+noun composition follows predictable semantics and parallels constructions in other languages (e.g., Spanish 'periodo orbital'), so a B1 learner knowing both constituents would very likely infer the MWE's meaning.
Etymology
Orbit period combines orbit, a path around a planet, and period, a length of time. Imagine the Moon moving once around Earth like a clock hand; the orbit period is the time it takes for that full turn, so it means 'the time to complete one full turn'.
