This has caused gaps in the tracking data for several hours each morning since day 093. It seems that the same or similar problem has affected other (?all) Z-18 receivers. We would obviously like to hear from anyone else with a Z-18 who has some information to share, or even better one that is still working! I have lots of rinex, log files and trap files from around time of the fault if anyone would like to compare the details, but obviously the main point of this mail is to inform the community of this problem and let you all know that I've stopped sending data from HERT until such time as we can find a solution.
