B.L.I.P.S. (Bluetooth Low Energy Indoor Positioning System) is a device designed to allow the tracking of individuals and large devices while indoors. This is accomplished through the use of Bluetooth beacons placed around the room, alongside Bluetooth low energy receivers placed on the people or devices being tracked. Positioning would be calculated by using the signal strength intensity of the beacons and calculating a corresponding distance. Through the use of triangulation, we should be able to find where the object or person is within a given room.

How it Works
How it Works
Using an inertial measurement unit (IMU), we can tell how our circuit is moving. The LSM9DS1, shown here, can read acceleration, gyroscope data (in degrees per second), and magnetometer data. Once our PCB (attached to identification badges) is moved, we can poll for bluetooth signals and triangulate position.
