This paper describes radio interference analysis between Global Posi- tioning System (GPS) and Industrial Scientific Medical (ISM) equipment. Due to increase of the usage of ISM equipment, the potential possibility of interfe- rence from ISM equipment to GPS system which used for safety life has been increasing. For the interference analysis between ISM equipment and GPS sys- tem, the scenario that GPS receiver operates in close to ISM equipment was set up. Then, protection distance between GPS receiver and ISM equipment was calculated in order to protect GPS system. The analysis result will be helpful for providing stable operation of GPS system.
