OPUS reports that Rapid-Static surveys are less than how many hours?

Rapid-static is a short-duration GNSS survey method used when you can’t stay long at the rover site. OPUS sets a practical upper limit for rapid-static sessions at less than 24 hours. Keeping the survey time under 24 hours helps keep atmospheric effects and satellite geometry stable enough for reliable processing and reduces the risk of data quality issues that can arise over longer sessions. That’s why 24 hours is the correct threshold. The other options don’t reflect this official upper limit, and a duration of 48 hours would exceed the guideline.
