Caution:
Do NOT use GLONASS when operating VelaSync as an A-GNSS
server, since this will likely crash the A-GNSS software.
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.
Note:
RINEX files (ephemeris data) must be updated no later than every 2
hours, because the ephemeris data is valid for 4 hours.
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
Station Name
to be used in the files gen-
erated by this unit so that their location can later be identified. Under
Record Duration
,
you can determine after how many days the history files will be overwritten.
Note:
YUMA files (almanac data) are valid for day.
The files can be remotely accessed via the
/pub
path on the VelaSync or via the mapped
drive.
