Standards and Data Formats

  • A complete set of GNSS Format examples with descriptions can be found at gAGE pages.

  • More details about Interfaces and Protocols can be found through NAVIPEDIA pages.

  • IERS Conventions: They define the standard reference systems to be used by the IERS. More information available at IERS web page.

Receiver INdependent EXchange (RINEX)

The RINEX format covers three different ASCII files: Observation, Navigation and Meteorological files

  • Release Notes can be accessed from here

  • Latest version 3.03 full paper is available here

  • Long Filename Creation: Recommendations on the new naming scheme for the RINEX 3 files can be found here

  • Information about previous RINEX versions can be found here 

Extended Standard Product 3 Orbit (SP3):

Format for GNSS orbit and clock solutions. An overview can be found here. Latest version can be found through this link.

RINEX-like Standards

  • IONosphere-map EXchange format (IONEX): Latest version can be download from here

  • ANTenna EXchange Format (ANTEX): Common standard to exchange Phase Center Offsets (PCOs) and Phase Center Variations (PCVs) of geodetic GNSS antennae. The Antenna Exchange Format specification can be seen here. A summary of the varios IGS antenna files can be found here.

  • RINEX Clocks: Common standard to exchange of postprocessed satellite and receiver clock offsets data. Format description can be downloaded from here.

  • RINEX-type Exchange File for GEO SBAS Broadcast Data: This contains the binary data broadcasted by some Space-Based Augmentation Systems (SBAS) like EGNOS and, WAAS collected in a specific time interval. Detailed information on the format can be found here.

Other Formats

  • Two Line Elementt (TLE): Format encoding a list of orbital elements of an Earth-orbiting object for a given point in time, the epoch. A description of the format can be found though the link.

  • Networked Transport for RTCM via Internet Protocol (NTRIP): It enables the mobile RTK GPS receiver (rover) to access data from the RTK base station over the internet to achieve 1cm accuracy. The protocol can be downloaded from here.

Tools
