I am asking because our aircraft are fitted with SBAS and depending on where RIMs station are located and if signals from geostationary satellites are being received.For the transmission of the SBAS signals currently some INMARSAT satellites are being used, hence my question are they traceable I.E by INMARSAT.
I can understand the concern, but INMARSAT still uses normal SBAS transponders, like on other satellites. They transmit a pseudo-GPS signal on 1575.42Mhz via a "bent-pipe" transponder. The only thing the satellites receive is the SBAS signal from ground stations, which is then retransmitted via the transponder. Thus you cannot be tracked via this means.
Using a normal SBAS transponder makes sense - because this way you don't need a special receiver just for INMARSAT SBAS.
I will quit banging my head, but darn, I love that icon.
