Global Positioning System (GPS) technology has become essential for modern communication and location tracking, raising significant security concerns. To protect sensitive GPS data such as coordinates and timestamps from interception, robust encryption before transmission is paramount. Through this paper, we propose the design and implementation of a secure GPS data transmission system resorting to fractional-order chaotic dynamics to efficiently cipher data. A fractional-order Hénon-type map is used to generate complex and unpredictable sequences. The encrypted locations are transmitted wirelessly and successfully decrypted at the receiver level by applying a particular synchronization technique between fractional-order chaotic maps ensuring that the response system’s geometric patterns closely match those of the driving system. Both simulation and practical results confirm the effectiveness of the proposed synchronization strategy in ensuring secure transmission of collected GPS data and their full recovery at the receiving side.
