CORSmap

Find CORS stations, compare distances, and plan your next GNSS trip with a primary and backup station.

INTERNATIONAL CATALOGUES
• Built-in sources from over 120 countries and territories, with partial coverage.

• Select the country based on your phone's location, without using your IP address. You can also search for a country or manually select a point.

• Map, list, search by city or code, and network filters.

• Straight-line distances and alerts when a base station is far from your location.

FIND FREE OPTIONS
• Filter: Free, No registration, or Free with registration.

• Copy server, port, mount point, format, and public connection instructions.

Review the terms and conditions and official registration for each operator.

• Personal credentials are not shared or used to monitor stations.

CONTEXTUAL STATUS
Each connection point displays its own status. Some sources allow you to estimate activity; others only publish a catalog. A published station does not indicate RTCM reception or a fixed solution. The data sheet explains what could be verified and when. A failed query does not necessarily mean the station is offline.

PREPARE YOUR PLAN
• Decimal coordinates, degrees/minutes/seconds, and UTM WGS84.

• RTK, static, and PPK plans with equipment, primary, backup, and notes.

• Favorites and your own stations that you can create, edit, and delete.

• Plans and catalog available offline. The map and updated queries require an internet connection.

• JSON backup to transfer your data to another installation and a work summary to share.

FREE AND WITHOUT A CORSMAP ACCOUNT
With a banner clearly identifying promotions for our apps. No subscriptions or personalized ads in this version. Access to fixes depends on each operator: it may be open, free with registration, or paid.

SOURCES AND SCOPE
Includes public catalogs from FUNDCORSRD, IGN Spain and regional networks, IGN Argentina RAMSAC, IBGE Brazil RBMC-IP, IGAC Colombia, IGM Ecuador REGME, RTK2go, and BKG IGS-IP/EUREF-IP. Partial coverage: does not contain all CORS networks in each country. A station may appear in several networks. Source and conditions are visible on each entry.

The coordinates in the catalog are approximate and are not control coordinates. A free and distant CORS network may not be useful for RTK at your location. Confirm frame, epoch, compatibility, access, and conditions with the operator. CORSmap is network-independent; it does not receive or transmit corrections, does not control receivers, and does not certify accuracy or cadastral approval.
