A .zip containing one or more static RINEX obs files. Multiple points are solved together; files are grouped by observation day (one network per day) and you get a separate report per point. Your observation day needs Sabah CORS reference data in the archive: that means 27 June 2026 (DOY 178) onwards, up to the previous day — today is still being ingested. A few earlier days also work (DOY 164–166, 169 and 174, 2026); the days between 170 and 177 are not archived. Processing takes a few minutes per day.

Occupy the mark for at least 3 hours. We re-solved four known CORS marks from windows of their own data, processing GPS+Galileo: every session from 1.5 h upwards met 20 mm horizontally (worst 13 mm). What a longer occupation buys is height — worst vertical error was 42 mm at 1.5 h against 11–17 mm at 3 h and above. So a short session is usable horizontally, but occupy for 3 h or more if height matters. Under 1.5 h cannot be solved against the CORS network at all and is rejected.

We will email your PDF report(s) here when processing finishes, so you do not have to keep this page open. Leave blank to just wait on the results page.
