Pseudo-Random Noise (PRN) Gold code was selected for utilisation as the Global Navigation Satellite System (GNSS) pseudo-range measurement code sequence. Recent studies revealed a potential security vulnerability issue due to the Gold PRN code utilisation in a GNSS-related cyber-attack known as GNSS spoofing. Here a PRN code construction method based on chaotic-form logistic map is proposed as an alternative to the existing Gold code practice. Dubbed Chaotic Ranging Code (CRC), is a PRN code generation method that generates ranging code with orthogonal properties as good as, if not better, then those of the Gold PRN code, while assuming the encryption embedded in the proposed CRC code provides improved GNSS information security.
