Global position system (GPS) and Local position system (LPS) have important rols in several applications in real life such as helthcare, monitoring and tracking, etc. GPS has many limitations due to some reason, the signal has lack when used inside bulding this is becouse of lack of line of sight (LoS). Therefore LPS is one of best solution which used to avoide weakness problem and it become very necessary for estimate userâ€™s or object position inside buliding with a good accuracy. This paper gives a servay on LPS technologies. Furthermore, the LPSâ€™s applications such as trackimg which is involved several types like human tracking, object tracking, animal tracking and AGV tracking which is done by previous researches are presented
