OPUS requires which file extension to process survey data?

OPUS processes survey data by taking in a GNSS observation file that contains the raw epoch-by-epoch observations from the receiver (pseudorange and carrier-phase data). The file extension .18o is the one that signals to OPUS that the file holds these observation records in the format OPUS expects. This helps the service correctly parse and use the data to compute positions. Other extensions like .shp (shapefile), .dat (generic data), or .T02 do not indicate the required observation data format for OPUS, so they aren’t recognized as suitable input for processing.
