The Propeller Corrections Network (PCN) integrates base stations worldwide. It simplifies the process of sourcing and uploading a RINEX file to correct your AeroPoint survey with satellite observations from a nearby base station.
By checking the coverage map, you can verify if your site is within the Propeller Corrections Network.
When processing data using the PCN, Propeller looks for a base station close to your AeroPoint survey and downloads an appropriate RINEX file covering the survey duration. It automatically applies corrections using that RINEX file and the base station coordinate reference system, taking the hard work out of correcting your AeroPoints data.
Because the Propeller Corrections Network needs a base station close to your survey, you can only use this method reliably if your survey is within approximately 25 mi (40 km) of a station in the network. Outside this radius, variations in the atmosphere between the base station and the AeroPoint survey cause the corrections to become unreliable, and the accuracy of your survey may be reduced.
This corrections method requires approximately 24 hours while the Propeller Corrections Network polls the base station for data.
Accuracy
| Global accuracy: | the best available, 20mm/20mm/50mm |
| Consistency: | the best available, 20mm/20mm/50mm |
| Internal accuracy: | 10mm or less — precise internal reconstruction |
The Propeller Corrections Network in the US produces coordinates in NAD83(2011). The PCN will be unavailable if a site is set up in a Coordinate Reference System based on a different datum.
Processing times expectations
While the Propeller Corrections Network is the easiest option, it is sometimes not the fastest. It often takes just a few minutes to complete. However, depending on corrections data release schedules and potential outages of base stations, it can take up to 24 hours.
If it's been longer than 24 hours and your AeroPoints are still being processed, our team of specialists will be notified and will start investigating the specific survey.
