The US government can track you using GPS as well. In fact, it's perfectly legal for the US government to stick a GPS tracker on your car and follow you without a warrant.
People who are paranoid of governments wouldn't use GPS anyway.
Do you even know how GPS tracking works?
How does a GPS tracking system work?
A passive GPS tracking system will monitor location and will store its data on journeys based on certain types of events. So, for example, this kind of GPS system may log data such as where the device has traveled in the past 12 hours. The data stored on this kind of GPS tracking system is usually stored in internal memory or on a memory card, which can then be downloaded to a computer at a later date for analysis. In some cases the data can be sent automatically for wireless download at predetermined points/times or can be requested at specific points during the journey.
An active GPS tracking system is also known as a real-time system as this method automatically sends the information on the GPS system to a central tracking portal or system in real-time as it happens. This kind of system is usually a better option for commercial purposes such as fleet tracking or monitoring of people, such as children or elderly, as it allows a caregiver to know exactly where loved ones are, whether they are on time and whether they are where they are supposed to be during a journey. This is also a useful way of monitoring the behavior of employees as they carry out their work and of streamlining internal processes and procedures for delivery fleets.
Real-Time GPS Tracking
Real-time vehicle tracking systems rely on both the Global Positioning System (GPS) satellites and a cellular system. A GPS tracking module continuously picks up the vehicle's precise coordinates, which determines the real-time location of the vehicle that's being tracked. Using a cellular data service such as GPRS, the tracking coordinates are immediately transmitted onto a secured server by pinging the device.
To sum it up for the American system...
A GPS receiver works for the user --
YOU. It does not send any data anywhere/anyone. Only to you via its display. The American GPS satellite does not have real time 2-way communication with your receiver and this is verifiable because there are plenty of commercial GPS receivers on the market and anyone of them will expose such a feature if found.
Real time GPS monitoring is not even 2-way communication, as explained by the two sources above. The GPS receiver in this situation does not work for you but for someone else. You may know about it like how a UPS/Fedex driver know or you may be ignorant about it like how a criminal is being surreptitiously monitored by the police. The GPS receiver/tracker execute a 1-way communication with the GPS satellites to establish the current location. Then it execute another 1-way communication path through another system to upload its current location.
Passive tracking mean the tracking device remembers its location points, allowed by its memory capacity, and upload that entire history
ONLY WHEN IT HAS ACCESS TO THAT OTHER COMMUNICATION PATH/SYSTEM.
Active tracking mean the tracking device must have a constant lock on that other communication path/system in order to constantly update its many location points. If for whatever reasons it does not have access or it lost that lock, mountains or tunnels or tall buildings, it may be designed to become a passive tracker and upload when convenient, or it may not remember anything at all and just dump the current location into that virtual trash bin.
But no matter which design, a GPS tracker does not use the American style GPS satellites to upload its location points. It must have an alternate communication path/system.
Not so with BDS...
BeiDou Navigation Satellite System ? News
I. About the service performances of BeiDou System
The main service performances of BeiDou System in China and its surrounding areas are as follows:
1. Positioning Accuracy: Horizontally, 10 meters, vertically, 10 meters;
2. Velocity accuracy: 0.2 meters per second;
3. Timing accuracy: one-way 50 ns;
4.Two-way high precision timing and short message communications service can be provided.
A BDS receiver can be designed to work only for you. Or it can be designed to work for you and the Chinese government via that 2-way communication capability built in into the BDS satellites. You may know about that design feature or you may be ignorant of it when you bought it. The manufacturer may be legally obligated to tell you that he is in cahoots with the Chinese government, or he may not be so legally obligated. He may tell you about it in the fine print legalese paragraph inside the user manual but then most likely you will disregard it anyway.
So which government should you really be paranoid about?
