It feels like there's some detail missing here. You can't just "drop" something from a satellite that's in orbit: it will also stay in orbit. So you need something to slow it down enough that goes low enough to start re-entry. Then there's the whole problem of re-entry. You can't just drop something and expect it to survive re-entry without burning up in the atmosphere unless it has things like a heat shield and a way of keeping the heat shield oriented so that it keeps acting like a heat shield. The missing details may be in the referenced book, but either way there certainly are some.
