To get the discussion started I've listed some of the basic GNSS observation format requirements below: 1) Support for GPS, Glonass and future GNSS constellations 2) Support for all observations available from each GNSS constellation 3) Format structure that allows for the addition of new observations within constellations 4) Observation numerical precision required for RTIGS and IGS applications 5) Observation Data compression 6) Support for GNSS receiver events such as: cycle slips, clock resets and tracking loop status etc The RTIGS II format should also have the followings support/features: 1) Available - data analysis and RINEX file conversion utilities 2) Publicly - available format documentation 3) Open source tools for encoding and decoding messages We would like to specify the requirements of the new RTIGS observation data format by the end of September of this year. Later in the fall the project will move to the format definition and implementation stage. If you are interested in contributing to the design and implementation of the new RTIGS II observation format please let me know.
