Can I track GPS when my phone is off?

Will the phone turn off GPS and be tracked? In terms of technology, tracking will be done, because in addition to GPS signal tracking, there are also mobile phone triangulation tracking, SIM card tracking and wifi tracking. GPS is disabled, but there is no GPS tracking, there are other tracking sources. Many devices can be tracked, not only GPS trackers, but also mobile satellite positioning, satellite navigation and even mobile applications. The variety of tracking methods makes us unable to guarantee our own safety. We can use GPS jammers or full-band jammers to stop tracking.
