This paper describes construction of the Inverse GPS based positioning system using 2.4GHz band radio signals to clarify the knowledge of system implementation and fundamental experiments to confirm the system behaviour. The system has two characteristics. To avoid influence of the received signal's power that makes large jitters, FSK (frequency shift keying) is used. In particular, to reduce the system's jitters, CP (continuous phase)-FSKis adopted. Considering the use of 2.4GHz wireless LAN (local area network) in the future, fundamental experiments are carried out at 2.4 GHz. In fundamental experiments, the system behaviour was confirmed, with the bias error and the random error of 0.1m and 0.03m, respectively. For the covering abstract see ITRD E134653.
