Re: [time-nuts] Any (relatively) cheap TSIP GPS receivers without WNRO out there?
Trimble replacement for EOL and WNRO was discussed here on Time-Nuts, five years ago (2015). Heol Designs is the solution. I have the Heol Design N024 GPS receiver in my Datum/Symmetricom/Microsemi TymServe 2100. == Cheap? TSIP drop-in? Relative term ... unless you desire a 19” door stop. Heol Design N0xx series https://www.heoldesign.com/-Trimble-GPS-replacement-boards- Heol Designs manufactures replacement GPS receivers (upgrade & update using Copernicus II chipset). Used for replacing Trimble iQ, SQ, SK2, LP, ACE II/III GPS receivers (due to EOL and WNRO). Contact Heol about your specific requirements/replacement. https://www.heoldesign.com/IMG/pdf/heol_design_like__series_en.pdf Datum / Symmetricom TS2100 replacement of Trimble Ace III using Heol N024 GPS receiver. Solves more than WNRO. https://www.heoldesign.com/IMG/pdf/heol-tech_note_119_en_r02.pdf greg w9gb == Date: Sat, 11 Jan 2020 20:54:16 -0700 From: Skip Withrow To: time-nuts@lists.febo.com Subject: [time-nuts] Any (relatively) cheap TSIP GPS receivers without WNRO out there?

ntpsec, a fork of the classic NTP distribution, supports an option to compensate for the 1024 week rollover: https://docs.ntpsec.org/latest/ntp_conf.html time1 sec Specifies a constant to be added to the time offset produced by the driver, a fixed-point decimal number in seconds. Each "g" on the end of the constant adds the number of seconds in a 10-bit GPS era; each "G" adds the number of seconds in a 13-bit GPS era.

Does your NTP server only work with TSIP or might it be able to use "standard" NMEA ? possible with PPS ?

Re: [time-nuts] Any (relatively) cheap TSIP GPS receivers without WNRO out there?
Hi Skip, Are your NTP-server using the Palisade ref clock driver? http://doc.ntp.org/current-stable/drivers/driver29.html If it’s using the event-poll mode you might need a receiver supporting that. I have not seen that outside the Palisade/Accutime family. Can you fudge the time1 all the way up to 1024wk (translated into seconds) to compensate for the wnro with your current receiver? # Set packet delay fudge 127.127.29.0 time1 0.020 - Björn Sent from my iPhone > On 12 Jan 2020, at 04:55, Skip Withrow wrote: > > I have an NTP server that uses a Trimble GPS receiver (Accutime 2000, > p/n - 39091-00, ROM 3.06) that has fallen prey to WNRO.
