Yup as I have said many times in the past the tracking sites are perfectly accurate where a satellite is unpowered - so if you want to know where the Envisat satellite is (a dead research satellite but easily visible to the naked eye) then the predicted positional information will be fine.

As soon as a satellite starts manoevering then all orbital predictions are wrong for the the duration of the move plus however long it takes for the TLE calculations to catch up which is normally a week or so.

The thing all tracking site users must remember is the tracking sites are predictions - not real time data. Ive seen orbital information displayed for a satellite in a decaying orbit where the tracking was still "live" several days after it had burned up in the atmosphere! After a week the site was corrected to object DECAYED

You may not understand but the rest of us do.

Well to put it simply the best place to look for accurate orbital positional information is right here on this thread from our guys with specialised equipment who track the identifying transmitter beacons on the satellites.

All the sources you have been posting from are inaccurate at the moment & will be for around a week after the final slotting at the final locations. TLE's for satellites are not (normally) updated daily. ABout once a week is the best you get from them

This morning, the telemetry signals switched to circular polarity. The 11704,60 H frequency switched to RHCP polarity, while the 12500,00 H frequency was switched off and the 12501,70 LHCP frequency was switched on.

it is likely that it has already started to move. In the next few hours I will check again to confirm if it has started to move.

According to the latest information provided by Eutelsat,Hot Bird 13F will start commercial operation at 13°E before the end of the third quarter of 2023, i.e. until the end of September.

Co z tym Hot Birdem 13F? [akt.]

Odkąd na przełomie maja i czerwca br. doszło w ramach pozycji orbitalnej 13°E do przeniesienia części kanałów telewizyjnych na nowego satelitę Eutelsat Hot Bird 13G, widzowie (głównie abonenci platform Polsat Box i CANAL+) z niecierpliwością czekali na koniec lipca, kiedy to według...

From this morning's check, it was still stationary in its position. While in the check just carried out, there is a slight shift towards the east...
He seems to have started moving eastward, further checks will follow in the next few hours and I will update you on his status for a possible move.

I checked again, it's about 2°E.
It appears to be moving east about 0,5~0,6 degrees per day.

The polarity of the telemetry signals are again linear, horizontal for both.

The TLE released yesterday is correct (continue moving east). The telemetry signals are always in circular polarity (horizontal for both).

oops, sorry (I messed up writing). They are in linear polarity, not circular.

Hello, I confirm the position, about 3.3° East.
