Decommissioned SVN24 (PRN24) now exhibits an orbital period of 750.55
minutes. That's indicative of its being boosted to a disposal orbit.
The satellite experienced a reaction wheel failure. It was launched
on 04 July 1991.

Boost to a higher orbit where it is out of the way.

Oh. I suppose there's not much between the GPS shell and the

There's not enough propellant aboard to deorbit. I suspect they
deplete what's left using the maneuvering thrusters to boost the

dead satellites are expected to encroach into the constellation
presenting a risk of collision.
The process isn't precise. Disposal orbital periods vary over a
fairly wide range.
