Geo++® GNWEB is an internet and intranet capable client / server application for the provision of (virtual) RINEX and other data of GNSMART reference station networks.

GNWEB offers internet users the opportunity to generate RINEX data for each provided GNSS reference station individually or virtual RINEX data for a user defined position to reduce distance dependent GNSS error sources. The user receives a report of the data availability and thus can check the suitability of the data prior to the actual download. The data requested by users are provided on the GNWEB server for a certain time period whereas the user has the opportunity to receive the data via a simple download or email attachment.
