While operating the firmware periodically resets the current date/time from the GPS signal. The date calulation is based on a 10bit week stamp from some epoch, so of any given configuration the timestamps will only be valid for ~20 years (1024 weeks). Per the instructions the dsp.config BASETIME.GPS_WEEK_REFERENCE value was changed from -1 to 2024. This value should fix the gps date until ~2030, at which time we will have to update the config again. We then used the sbcclient to load this config file into firmware. This config update appears to have fixed the date/time issue we had over the last week. During this work we also swapped the gps data disk out with a blank spare. Current disk will be shipped back to Boulder this week. ___end___ Wed Jul 29 19:01:52 GMT 2020 KCOR End Patrol Wed Jul 29 19:01:53 GMT 2020 KCOR Start Calibration script: c:\kcor\mlso-calibration22deg-20171025.ini Wed Jul 29 19:17:07 GMT 2020 KCOR End Calibration Script Wed Jul 29 19:17:23 GMT 2020 KCOR Start Synoptic Patrol Wed Jul 29 19:17:24 GMT 2020 KCOR Start Synoptic Patrol Wed Jul 29 20:18:07 GMT 2020 KCOR End Patrol Wed Jul 29 20:18:08 GMT 2020 KCOR End Patrol GENERAL COMMENT BY berkey: Wed Jul 29 20:21:08 GMT 2020 PM Blew off Kcor Field Lens to get rid of a blob in the SW. ___end___ Wed Jul 29 20:21:34 GMT 2020 KCOR Start Synoptic Patrol GPS COMMENT by MLSO: Wed Jul 29 21:45:10 GMT 2020 Successfully logged in to system Unable to mount disk GPS software running Last 5 GPS data files are: /mnt/usb/dataoutiq_2018_012_2143.bin 2147483647 /mnt/usb/dataoutiq_2018_013_2143.bin 2147483647 /mnt/usb/dataoutiq_2018_014_2143.bin 2147483647 /mnt/usb/dataoutiq_2018_015_2143.bin 2147483647 /mnt/usb/dataoutiq_2020_211_1958.bin 265636608 ___end___ Thu Jul 30 00:53:15 GMT 2020 KCOR End Patrol Thu Jul 30 00:54:32 GMT 2020 Kcor Focus/alignment program exited Thu Jul 30 01:00:41 GMT 2020 KCOR Start Synoptic Patrol Thu Jul 30 03:41:39 GMT 2020 KCOR End Patrol GENERAL COMMENT BY berkey: Thu Jul 30 03:46:51 GMT 2020 Nice weather all day. ___end___ ONSITE STAFF: berkey
