> It operates its own GNSS constellation.

Only 33 years later and mostly launched on Russian rockets, behind GLONASS and BeiDou.

> It is second only to NASA. Calling it a failure is ridiculous.

In what respect? Space? Certainly not, far behind the US and Russia and questionably competitive with China.

Economically? Behind US and China.

R&D? Behind US and China.

Manufacturing? Behind US and China.

You are refusing to recognise reality.

Russia had its last deep space mission (failed) in 1996. GLONASS did not operate until 2005.

Chinese contributions to scientific space missions had been very modest although am sure they may catch up later.

NASA has 3x the budget of ESA. The question was if the EU method of doing project works and it does in very unambiguous manner.

    Five years before Galileo.

    As the EU falls economically and scientifically behinds what used to be our peers, it's obvious that it _doesn't_ work. Refusing to recognise that reality is a spectacular example of the Ostrich effect,

Not all satellite systems are equal:

>The US constellation isn’t as accurate as the newer networks, said Roberts, the Sydney-based professor. “It used to be GPS was out in front,” he said. Now, though, the EU’s Galileo is in the lead, with China’s BeiDou close behind, he said.

It's basically Galileo > BeiDou > GPS >>> GLONASS.

  • That would be expected for a system launched 33 years later, but in Galileo and GPS are identical for civilian use (and obviously no-one knows the military capabilities of Block III satellites as that's undisclosed).

    GPS+Gailleo is the current SOTA, but it's nonsense to say Galileo is "best".

    • Galileo has signal authentication, GPS doesn't. In a world where GNSS spoofing is increasingly becoming a hazard to aviation and other applications, that's arguably critical.

  • And frankly accuracy does not matter.

    for navigation using Code method GPS-tier is basically good enough.

    for precise measurement you use phase measurement of the signal, and what you care about is good(low) DoP of constellation and amount of satellites within sight-line - not from which system they come(to oversimplfy it a bit)
