Abstract Provided are a receiver for synchronizing with a global navigation satellite system (GNSS) including a plurality of satellite vehicles (SVs) and a method thereof. The method includes the steps of: starting a verification process and a bitsync (BS) process in parallel with a first SV among the plurality of SVs; and upon completing the verification process while still performing the BS process, targeting a track channel process with the first SV based on an interim BS result obtained at the time of completing the verification process, and starting a frame sync (FS) process with first SV based on the interim BS result. 복수의 위성 차량(SV)을 포함하는 글로벌 위성 항법 시스템(GNSS)과 동기화하기 위한 수신기 및 그 방법이 제공된다. 방법은 복수의 SV 중 제 1 SV와 병렬로 검증 프로세스 및 비트 동기(BS) 프로세스를 시작하는 단계, 및 BS 프로세스를 수행하면서 검증 프로세스를 완료하면, 검증 프로세스의 완료 시 획득한 중간 BS 값에 기초하여 제 1 SV로 트랙 채널 프로세스를 시작하고, 중간 BS 값에 기초하여 제 1 SV로 프레임 동기(FS) 프로세스를 시작하는 단계를 포함한다.
