Performance Assessment of Non-Integer-Hour Data Blocks in BDS Broadcast Ephemeris

IEEE Access
Due to system anomalies, BeiDou navigation satellite system (BDS) sometimes updates the broadcast ephemeris at non-integral hours. The gross errors contained in the non-integer-hour data blocks of broadcast ephemeris will lead to the signal-in-space (SIS)
