Claude - Let’s start with the HP/Symmetricom 58503A/59551A manual (leapsecond.com) http://www.leapsecond.com/museum/hp59551a/097-59551-02-iss-1.pdf
Use an appropriate Serial Cable for the SatStat program to access the 59551A. The HP/Symmetricom 59551A uses SCPI commands for configuration. == Earlier instructions existed here on Time-Nuts for setting the current time to the receiver, BEFORE accessing GPS satellite data. This worked for my HP/Symmetricom Reference. == Access your HP/Symmetricom 59551A with SatStat, while it is disconnected from the GPS antenna (before Satellite Acquisition). You should be able to set your location coordinates, current date and time in NVRAM. Shown in the Manual, Chapter 5 (CommandReference), page 5-7 “Facilitating Initial Tracking” == greg, w9gb === Date: Mon, 08 Nov 2021 17:01:05 -0500 From: va2...@ebox.net Subject: [time-nuts] HP/Symmetricom 59551A showing wrong date To: time-nuts@lists.febo.com — Hello to all members of the list. I'm testing an HP/Symmetricom 59551A that powers up OK and if I connect an antenna the "GPS LOCK" LED lights up after a while. The receiver is tracking satellites, but the status screen shows wrong date and time, please see attached screen capture. Is this a case of a GPS receiver not counting week 1024 correctly ? Thank you for your help, Claude, VA2HDD _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com -- To unsubscribe send an email to time-nuts-le...@lists.febo.com To unsubscribe, go to and follow the instructions there.
