United Kingdom Global Navigation Satellite System  The United Kingdom Global Navigation Satellite System (GNSS) is in development to replace the European Union’s Galileo Global Navigation Satellite System after Brexit. The United Kingdoms GNSS will be run by the United Kingdom‘s Space Agency. Satellites are planned to be launched from Scotland using a vertical launch platform in 2025, with the United Kingdom GNSS planned to be fully operational by 2030. It is estimated that the cost of the new United Kingdom GNSS will be £5,000,000,000. The United Kingdom government has said that it wants the United Kingdom GNSS to be openly compatible with the United States Global Positioning System (GPS) and Five Eyes. Both the United States of America and the other Five Eyes nations are contributing their expertise to assist the planning and construction, and in exchange these nations will gain access to the United Kingdom’s GNSS encrypted area after it is launched. The United Kingdom GNSS was first discussed by the UK government in May 2018 when the European Union told the United Kingdom that it would no longer be able to use the secure component on European Union EU Galileo,  the EU equivalent to the USA’s GPS. On 21 November 2019, the United Kingdoms Space Trade Association (UKSA) released a United Kingdom Space Manifesto, in which they state that the United Kingdom "participation in a new global satellite navigation system must be secured". The UK's Ministry of Defence also found security faults within the EU Galileo, and that was another reason that the United Kingdom began work on its own Global Navigation Satellite System. One suggested name for the UK Global Navigation Satellite System GNSS is Newton, after the English mathematician Sir Isaac Newton.
