I had GPS rollover when shifting from EOPL to Singapore AWPA anchorage. With that, ECDIS indicated a problem with the SA digital certificate. “Invalid ECDIS SA (Scheme Administrator) digital certificate”.
The GPS date was set to 2002.
I was using Transas’s ECDIS Wartsila Navi-Sailor 4000. The system was linked to a FURUNO GPS type GP150.
The S63 Security Scheme Administrator certificate, commonly known as the SA digital certificate, failed to acknowledge the ENCs trying to install it.
IHO is the holder of the SA digital certificate. IHO S63 Scheme Administrator, International Hydrographic Organization (IHO), Monaco, MC.
The present SA digital certificate is valid from February 6th, 2013 until March 3rd, 2033.

The data supplier also sent us a fresh IHO certificate, but it didn’t function.
ECDIS denied weekly ENC updates beginning in week 1 of 2022 owing to an invalid SA digital certificate.
The ECDIS unit’s date has been altered to 2002. However, the SA digital certificate installed on the machine is from after 2013. All of the ENC upgrades and permissions I was attempting to install were post-2013.
This issue arose as a result of the FURUNO GPS rollover, however initially, we attempted to resolve it as best we could without updating the GPS software.
Finally, a shore technician assisted me in Colombo, Sri Lanka. The FURUNO GPS software was upgraded, and the ECDIS devices were synced with it. After that, I attempted to install the new ENC permits and updates, and the operation was completed successfully.
