Abstract
An anti-jamming time synchronization method and apparatus for maintaining time synchronization between a global positioning system (GPS) and a satellite-based augmentation system (SBAS) are provided. The anti-jamming time synchronization method includes receiving a GPS signal from a GPS satellite using an omnidirectional antenna, receiving an SBAS signal from an SBAS satellite using a directional antenna, calculating measurement values of the GPS signal and the SBAS signal, decoding a GPS message of the GPS signal and an SBAS message of the SBAS signal, when the measurement values are values within a normal range, synchronizing time with GPS time based on a measurement value of the GPS signal and the GPS message, and when the measurement values are values beyond the normal range, synchronizing time with the GPS time based on a measurement value of the SBAS signal and the SBAS message.
