RTCM3EPH01 are same as the broadcasted ephemeris
IGSxx are orbit and clock corrections without the ephemeris, you can use them with "broadcast+SSR APC/CoM" option
from rtklib.
Ok eltorio. Thanks for this commet as well. As I can understand the word "brodacsat", inside the Satellite/ephemeries, is related to the infos coming from the receivers, both Rover (Input Stream 1) and/or Base station (Input Stream 2), if none of them can issue ephemeries I can recover those infos by Input Stream 3. Correct?
from rtklib.
Correct you can provide the ephemeris on each stream on PPP I use 1 for receiver, 2 for ephemeris, 3 for SSR.
"Broadcast" means more something "broadcasted from the satellites" even by the air (normal reception) or by ntrip caster (RTCM3EPH01) ,
Some receiver does not output the ephemeris that's why RTCM3EPH... may be useful.
IGSxx gives you some correction of the satellite orbits (position/speed) and satellite clocks error.
By using "Broadcast+SSR APC/CoM" you will construct some better ephemeris by combining the broadcated ephemeris with the correction.
APC or CoM depends on the correctrion stream (phase center vs center of mass)

Thanks again, very helpful. David
