Can we help you?

Robust and easy to use, the Net20 PRO a long term investment.

Its efficiency and flexibility assure you high quality data for your projects, and for many years.

Ensure the proximity and reliability of your reference station while eliminating your RTK corrections service charge. Net20 PRO provides you superior connectivity and accuracy in addition to controlling user’s access. The Net20 PRO can be controlled with NTRIP Caster software. RTK correction can be transmitted by DIP and NTRIP:
  • Transmission of RTK corrections permanently with simple local internet connection from your (LAN) working network.
  • Gérer vos utilisateurs avec un contrôle sur l’accès à votre adresse IP et de la disponibilité de vos données de correction

1Accuracy and reliability are generally subject to satellite geometry (DOPs),multipath, atmospheric conditions and obstructions. In static mode, they are subject to occupation times: the longer is the Baseline, the longer must be the occupation time.

2Depends on SBAS system performance

3Network RTK precision depends on the network performances and are referenced to the closest physical base station.

4Varies with the operating environment and with electromagnetic polution.

5 Only model w/o radio.
