Q: Do GlobalTop GPS receivers based on MediaTek MT3329 chips support SBAS mode for fix-rates higher than 5 Hz?
No, GlobalTop GPS receivers based on MediaTek MT3329 chips do NOT support SBAS mode for fix-rates higher than 5 Hz. For fix-rates equal to from 6 to 10 Hz, these GPS receivers will not enter SBAS mode to avoid data loss due to long calculation times.
