A GPS satellite orbits the Earth approximately twice per day.

Here's how to calculate that:

* Orbital Period: GPS satellites have an orbital period of around 12 hours.

* Days in a Week: There are 7 days in a week.

* Orbits per Week: 2 orbits/day * 7 days/week = 14 orbits per week

So, a GPS satellite orbits the Earth approximately 14 times in a week.
