GPS within Workspace ONE is mainly meant to help administrators locate lost or stolen devices. Some companies attempt to use it to track employee specific locations, however it was never built for that purpose.
The device location reported within Workspace ONE is an approximation. It does not work like traditional GPS applications that collect data on a real-time basis. Information only updates when the device moves across cell towers or Wi-Fi hotspots. Also, GPS info is only updated when the Agent sends a sample of info (which is not continually). All of this is done only to get an approximate location of the device and not real time tracking. The reason behind this is that the GPS is a very battery intensive operation.
