Motion coprocessor replacement in 2019 iPhones may power Apple Tags
Apple is making major improvements to the coprocessor in the 2019 iPhones, a report claims, with the codenamed 'Rose' and 'R1' part included in the A13 chip with a wider array of sensors than found in previous M-series coprocessor iterations.

The A-series chips used in the iPhone have included a M-series coprocessor for some time. Also known as a Motion coprocessor, the component is used to collect sensor data and process them on behalf of the main processor, freeing up resources for other tasks and reduces battery usage.
Typically the motion coprocessor takes data from the accelerometer, barometer, gyroscope, microphone, and compass, among other elements, enabling it to determine its physical location and movement in 3D space, as well as collecting data for step counts and other items. The new "Rose" coprocessor considerably expands the list of sensors it can acquire data from.
According to a report on Tuesday by MacRumors, there is support for an inertial measurement unit, Bluetooth 5.1 features, Ultra Wide Band support, and both motion capture and optical tracking data from cameras. The data is able to enhance its positioning data, but the addition of Angle of Arrival and Angle of Departure from Bluetooth 5.1 enables Bluetooth direction-finding, which can be used to help find the position of lost Apple Tags.
Revealed at the end of August, the Apple Tags are a Tile-like tracking device that allows users to find them via an app and, in turn, the thing it is affixed to, such as keys. Running within the Find My app, users would be able to generate an AR-style view showing where the tag is detected to be in relation to their own position, potentially aiding in its discovery.
A Ming-Chi Kuo research note on Friday also mused on the use of Ultra Wide Band, but less from a consumer viewpoint. Kuo suggested UWB could be used to enhance indoor navigation alongside iBeacon technology, making it easier for iPhone users to navigate a campus or large building, such as a stadium.
Since "Rose" has a considerable amount of overlap over what the M-series coprocessors collect, it is likely it will replace the Motion coprocessor entirely.

I think it is much more likely that this new processor is to enhance AR by supporting more sensor inputs. These extra sensor inputs might include the rumored third camera lens, headset hardware is also likely to have an accelerometer and gyroscope and there might be other hardware for interaction in the AR world such as a sensor laden glove.
True they did. But the UWB technology would not be a part of what was mentioned, which was how to use other iOS devices to help track the location of your “lost” device.
UWB has more do with pin-pointing the beacon down to an inch or so to make it easier to find (and exactly positioning it in an AR scene).
I’d be willing to bet it’ll be an extension to their iBeacon API. The only thing they’d need to add is an extra bit of data; the GPS coordinates. Currently iBeacons provide signal volume level which can be used to determine if you’re getting closer to or further from the beacon.
While this tracking technology has a lot of potential uses, it could provide additional ways to track another person without the individual knowing. Examples include stalkers who want to know you whereabouts, or burglars who want to know your routine so they can plan their next robbery at your home.
If someone can surreptitiously attach a tracker to an automobile or a suitcase or other personal item, this could turn into a scary situation. How do you handle that Apple?
