Out of curiosity, what is the longest (duration) continuous Static Observation that you have ever done.
I think my personal “record” is something like 56 hours on an RTK Base Station out in the Deep Creek Mountains (I turned the radio off at night).

Well, lately the longest was 96.8 hours and then the unit got full. Actually it was by accident. I just wanted a nice 6 hour session but some friends came over and jumped in the pool. And one thing led to another and I forgot about the unit sitting on PaulkW.
I haven't sent it in yet. Still recovering from the pool last weekend.
3 days-74 hours I think. Left it on at the office base over the weekend.
Around 10 hours as a continuous observation, but that particular point had multiple days of 10 or so hour observations on it.
I would park one unit on a HARN marker and another at a central on site point in the morning and move two other units around hourly to set additional control.
Unless OPUS has been revised it won't process any file with data from more than two GPS days. I had one last year just 26 hours but it had data in three GPS days. Wouldn't work until some of the data was clipped off.
I recall a remote project that I worked on in the 'olden' days of GPS where access to a couple of the occupation stations was by helicopter only. When we flew into to the first station I hooked up multiple batteries and set it to log at a 30 second epoch rate, prepared for the possibility that I might not be able to get back to it later that day due to weather grounding the helicopter.
As luck would have it, due to weather conditions I wasn't able to retrieve the receiver until more than three days later. I was quite relieved to find that it was still happily logging away while I had been visiting other stations by truck and ATV during that period.
If memory serves there was (as in Moe's case) about 74+ hours of continuous data in a single observation file.
between 8 - 10 hours per day for 2 days. i was the pivot man on a big network back in the late 90s that required that same point to be occupied all day twice in a row while other static sessions moved around it. i sat in the truck and read a book for 2 days peeking out ever couple of hours to check and make survey we were still plumb and recording data. BORING!
4 1/2 hours for survey USA day.... I don't do long term static collection often...
Over 6 years and running. With maybe half a day break to replace the antenna with a GNSS one.
Of course this is a RTN base part of the Leica network, however it collects static data 24 hours a day.
Many years ago I was sent to Trindad with three new gps units. Plan was to set one at the top of Port au Spain telephone company buiding and let in log data while I went around the island setting new points and finding and occupying some old transit satellite points We also had units logging data in Aberdeen, Houston, and another guy like me somewhere in South America. I had to go back to the primary station every two days to download data and reset the memory but it ran for a couple of weeks. I also have a Leica network base that has been collecting data since 2005 and before that I had a Trimble 4000 connected to the Trimble Ref Station software collecting 24hrs aday for several years.
