You can often "decimate" the data (e.g., if you recorded at 1Hz but only need 30-second intervals for static processing).
Most major hardware brands provide their own converters to ensure 100% data integrity: Trimble Configuration Tool / Convert to RINEX. Leica: Leica Spider or Leica Infinity tools. Topcon: Topcon Receiver Utility (TRU). How to Perform a RINEX 3.0x Conversion
In the world of high-precision surveying and GNSS (Global Navigation Satellite System) data processing, the is the universal language. Whether you are working with GPS, GLONASS, Galileo, or BeiDou, converting raw satellite data into a usable format is a critical step.
While no longer actively updated by UNAVCO, TEQC remains the "Swiss Army Knife" of RINEX. It is a command-line tool used for quality checking, editing, and converting GNSS data.
