lection of RINEX3 navigation files and almanac files for the GPS, Galileo and/or BeiDou
constellations. At this time the GLONASS constellation is NOT supported.
Based on accessible and valid GNSS data, VelaSync generates its own ephemeris and
almanac data, and stores it in RINEX files and YUMA files, respectively.
You can also determine how often, or at what time each day the YUMA almanac files will
be created. Also, you can assign a 4-character
erated by this unit so that their location can later be identified. Under
you can determine after how many days the history files will be overwritten.
The files can be remotely accessed via the /pub path on the VelaSync or via the mapped
drive.
