[IGS-DCWG-127] Re: SP3 of SBAS

[Nacho Romero]

Mr Cong Huu,

sorry but in the IGS we do not estimate orbits for the Geostationary 
GNSS satellites or the SBAS.  The SBAS only have single frequency 
measurements and as the IGS always processes using the Iono-free 
combination such satellites with only L1 data are not processed.  For 
the Geo satellites with 2 frequency data (Beidou) as far as I know we 
also do not do precise orbits, on the other hand the orbits you can find 
for the IGS products are in the two ftp directories below. Keep in mind 
the current week is 1864 so check for at least two weeks back since 
delivery of precise SP3 orbits is delayed some days as we wait for 
station data;

ftp://cddis.nasa.gov/gps/products/
ftp://cddis.nasa.gov/gps/products/mgex/

general description of the products:
