ShadowCuff Location Tracking 

1. ShadowCuff uses a combination of GPS, WiFi and LBS data for location tracking
   
2. The tracking priority is GPS > WiFi > LBS
   
3. Location points are configurable from 30 seconds to 5 minutes
4. All location data is recorded within the enrollee's profile in the ShadowtrackONE platform
   

When the ShadowCuff is open and connected to the charger, it continues to gather location data but does not send the battery level, causing locations to be plotted without displaying a battery percentage.

Satellite Constellations Utilized by the ShadowCuff

1. The ShadowCuff is designed to search for and utilize satellites from various global positioning systems, including GNSS with GPS, Galileo, BDS, and GLONASS. It automatically selects satellites with the strongest signals to ensure optimal performance. This advanced technology allows the ShadowCuff to use more than three satellites simultaneously for accurate and reliable tracking.
   

1. Simultaneous Acquisition: The ShadowCuff attempts to obtain both GPS and WiFi data within each packet.
   
2. Preference for GPS: If GPS data is available in the packet, it is given priority and used over WiFi data.
   
3. Fallback to WiFi: If no GPS data is obtained in the packet, the ShadowCuff will use the available WiFi data.
   
4. Fallback to LBS if no GPS or WiFi: The ShadowCuff will then attempt to plot an LBS point.
   
5. No Direct Switching to WiFi: The ShadowCuff does not switch from GPS to WiFi directly. Instead, it continuously tries to get both types of data in each packet and prioritizes GPS when available.
