Talk:Galileo (satellite navigation)

message: The article says that EGNOS "is a system of satellites and ground stations designed to increase the accuracy of the current GPS and GLONASS in Europe." Does it have anything to do with Galileo? If not, that sentence should be deleted.
No, EGNOS does not have anything to do with Galileo. I have deleted the paragraph.
EGNOS is the first step to an GNSS infrastructure of Europe. As such related to Galileo.
:EGNOS will in it's third version also increase the accuracy of Galileo starting hopefully in 2024. --Rabenkind (talk) 17:12, 26 June 2022 (UTC)

message: "Since Galileo was designed to provide the highest possible precision (greater than GPS) to anyone, the US was concerned that an enemy could use Galileo signals in military strikes against the US and its allies (some weapons like missiles use GNSSs for guidance). The frequency initially chosen for Galileo would have made it impossible for the US to block the Galileo signals without also interfering with its own GPS signals. The US did not want to lose their GNSS capability with GPS while denying enemies the use of GNSS."
The article needs to be clear on how the US would go about blocking Galileo signals. Stefán Örvar Sigmundsson (talk) 23:41, 12 May 2016 (UTC)

thread_title:  Blocking ability 

message: The UK (Surrey Satellite Technology Ltd (SSTL)) currently is responsible for constructing the payloads for the first 22 satellites. The tender process for the remaining satellites and payloads is currently underway, with SSTL bidding again.
While the UK will remain an ESA member, general rules mean that joint-funded missions between ESA and the EU (like Galileo) have to be sourced from EU countries. This situation becomes even more complicated because Galileo has direct funding from other nations - e.g. Switzerland is non-EU, but is ESA and was able to contribute the internal clocks. 
However SSTL's construction of the payload is a huge security role, and it's distinctly uncertain whether the EU would be willing for a non-EU member to have such (possible) influence, especially given that by dint of constructing the payload, SSTL is heavily involved in dealing with the public regulated service - including the specific encrypted part for military/governmental use. Norway and Switzerland have not been granted access to this, despite security treaties. 
Deserving of its own sub-section, or best suited to splits across multiple other paragraphs (bearing in mind that there isn't currently mention of the ongoing tender processes)?

message: The article states that since Bill Clinton removed selective availability (SA) for the open/civilian GPS signals (C/A code), the military and civilian signals have the same accuracy. While it is true that SA intentionally degraded C/A code performance, even with SA off the signals have a lower bandwidth than the encrypted military signals (P and M) which means civilian signal accuracy still isn’t as good.  Other enhancements used by civilian receivers to augment their GPS derived position may allow significant performance enhancements over plain C/A code but it is not correct to say that with the removal of SA the military and civilian signals are on par. 74.104.157.200 (talk) 01:07, 22 March 2022 (UTC)

message: Whats the thing with all the feed, inches, miles and lb? This is not an article closely related to one of three countries using those measures. It is an scientific article of a European project. It makes it so much harder to read. Who on earth is interested in satellite navigation and doesn't know SI-units? I suggest removing all non-SI units from running text. --Rabenkind (talk) 17:09, 26 June 2022 (UTC)

message: Wikipedia says:
https://en.wikipedia.org/wiki/Galileo_(satellite_navigation)#Receivers
"Effective 1 April 2018, all new vehicles sold in Europe must support eCall, an automatic emergency response system that dials 112 and transmits Galileo location data in the event of an accident".
Does this mean that if I buy a new car in Europe and pay for a preinstalled navigation, it also supports Galileo? 
If I buy a car with built-in navigation in Europe, how do I know if it supports Galileo or not?
And if there is such support, is the navigation significantly better than without Galileo?
