A replacement GPS receiver card for Symmetricom SyncServer, XLi and XL-GPS clocks that lost time sync on 18th September 2022 due to a week number roll over event in the OEM cards supplied by Furuno.  This card directly replaces the failed card to restore correct timekeeping.  You might need to perform a factory reset of the server to reset the internal clock if it no longer shows the right date.  And/or adding three or more public NTP servers as external time references may also help reset a wildly incorrect time/date being displayed (often as a result of the CR2032 battery being depleted).  Those can be deleted once the new card has achieved sync.  I have found that just replacing the card and powering the unit back on seems to work fine most of the time.   The buyer is responsible for installing the card and is expected to have basic engineering skills and tools.  Note that the MMCX antenna connector is a surface mount device and can be ripped from the board with relatively little force.  So it is very important that when connecting or disconnecting the antenna pigtail cable you securely hold the socket (and not rely on the connections to the board to provide the opposing forces to the insertion/removal force applied to the MMCX plug).  Damage done to the surface mounted socket is not covered by the seller's warranty.  Technical support is not included, but the job is straightforward.  The card is held in place by four screws and provided that care is taken to insert the 10 connection pins on the underside carefully before the screws are re-inserted and to re-connect the antenna pigtail cable by pressing the connector square to the circuit board so as to avoid bending the center pin you should be fine.  I usually reconnect the antenna pigtail cable before guiding the 10 pins into their sockets.  Anti-static precautions should be observed during the procedure and the power cable should be disconnected.  The card may take a little longer than normal to achieve lock when first used as it will need to download the GPS almanac and triangulate its position.  Subsequent cold starts should be quicker (under 30 minutes to lock, with a good antenna).
