This unit has been upgraded with a \u003cb\u003enew, latest\ngeneration GPS receiver\u003c\/b\u003e module from ublox. It is\ntherefore unaffected by the September 18th 2022 week number\nrollover event that caused most SyncServers to fail to sync\nto GPS. The new card is good for accurate GPS time and date\nreception until beyond 2037. The new card will typically see\na few more satellites than the OEM original product.\u003cbr\u003e\n4.
