These objects could very well be balloons that NASA routinely deploys into the atmosphere in order to give viewers the impression that satellites are real.
Hogwash. Balloons don't behave like that. If they were balloons, they would not stick to defined paths. They would be at the mercy of wind and weather.
Also,
http://sgf.rgo.ac.uk/.... and why is it always and only about NASA, when most of the satellite launches in the past, and upcoming, are/were non-NASA craft?
... and, as I posted elsewhere;
There are a host of independent operators who track these craft.
There's a satellite industry in most all civilised countries of the world.
You can buy the radio amateur equipment to listen in to transmissions from the ISS as it goes by.
You can hire/buy your own satellite uplink/downlink truck, in pretty much any locale of the world.
You can buy/rent a portable satellite rig, such as that used by remote news gathering crews, and buy/rent airtime on comms satellites to transmit whatever you want to a remote location elsewhere.
You can buy tracking telescopes, which can track moving satellites across the sky for you.
You can photograph the geostationary satellites with the most basic consumer-grade cameras.
