PNW
CORS Network Management and Network RTK Software
Manage your reference network.
Deliver precise positioning.
Manage CORS stations, subnets and correction services on one platform. Support Network RTK workflows by modelling atmospheric and orbital errors.
From network data
to positioning services.
PNW provides correction information to rovers by modelling errors from the ionosphere, troposphere and satellite orbits.
Connect stations
Define receiver, antenna, coordinate and connection information.
Process the network
Monitor observation quality; manage subnets and virtual points.
Deliver the service
Transmit Network RTK corrections appropriate to the user's location.
Monitor stations.
Configure services.
Manage users, mountpoints and subnet definitions. Check station status, coordinate changes and historical records.
Beyond correction services.
Use network data with archiving, quality control and post-processing tools.
Observation archive
Store RINEX 2.x / 3.x data hourly or daily and transfer it via FTP.
Quality and integrity
Monitor reference data and satellite information; examine coordinate changes.
Online post-processing
Automatically select reference stations and report results in the user's coordinate system.
Virtual grids and subnets
Configure subnets, virtual points and correction transmission according to user location.
Geodetic tools
Include geoid, velocity field and transformation parameters in the service.
Meteorology module
Evaluate atmospheric data with TEC and PW calculations.

- Capacity and reliability values are software capabilities stated in Atay's technical table. Actual capacity is assessed according to licence, modules, server, network infrastructure and station configuration.
- The operating-system list reflects compatibility information on the Atay page. Compatibility between the deployed PNW version and operating system must be verified separately.
