Just by the nature of how that expansive network functions, there is no similar alternative that you can control the privacy of.

The alternative would be a GPS transponder intended for vehicles, such as LoJack, or something similar. They are going to have power and subscription requirements, usually cost $1000 for the hardware etc. And in that scenario you still have to “trust” the vendor to a degree.
