New features of Version 6.02 of the TopNET CORS software include: support for new meteorological devices (Paroscientific MET 3/3A Sensor) and additional capabilities in the download center, enabling the combining of multiple files for a day's work into a single daily file (RINEX). The TopNET RTK module includes the TopNET CORS functions along with the following new features: RTK correction data in the RTCM 3.0 and CMR+ formats, and Ntrip caster distribution to network users. This protocol is currently supported in TopSURV field collection software; its addition within TopNET adds security and the ability for network operators to create authentication with specific user name and password protection.
