This work includes development of board schematics, PCB layout and firmware development. The board project was developed in Altium Designer. The PCB has 4 copper layers. I used minimum sized antennas, and the GPS antenna signal has an additional option of connecting an adhesive antenna. The final product is a Li-ion battery powered GPS bracelet.
