Heol Designs offers replacement boards for Trimble GPS receivers. http://www.heoldesign.com/N01x-Trimble-Lassen-SK2-iQ-sQ-LP-ACE-replacements-boards Heol Design's GPS receivers are based on the Copernicus II high performance GPS chip set and mimic the legacy Trimble GPS receivers. These OEM boards are designed for use in embedded and industrial applications requiring high accuracy positioning and timing information. They can also be used as a replacement and upgrade for users of the Trimble Lassen iQ, SQ, LP, SK2 and ACE (ACEII, ACEIII) receiver boards, which are now EOL (end of life). Some time-nuts members are using the Heol Design N024 solution in their Datum Tymserve 2100, which also corrects 2 additional firmware/hardware bugs. http://www.heoldesign.com/N024-GPS-receiver-board-for-Tymserve-2100 Sent from iPad Air

I considered that. Unfortunately the Heol Designs units don’t emulate the SV6-CM3 and the Ace receivers were not a direct replacement. So it seems they have nothing to offer at this time. > On Jan 18, 2017, at 1:24 AM, Gregory Beat <w9gb@icloud.com> wrote: > > Heol Designs offers replacement boards for Trimble GPS receivers. > http://www.heoldesign.com/N01x-Trimble-Lassen-SK2-iQ-sQ-LP-ACE-replacements-boards > > Heol Design's GPS receivers are based on the Copernicus II high performance GPS chip set and mimic the legacy Trimble GPS receivers.
