Latest updates[?]: 2013 updates: Spectrum clash with China's Beidou looks unfixable; Early services will be a year late; EU looks for ways to force Europeans to buy Galileo services; 1st 3D position fix from Galileo; GGTO offset for GPS now live; Galileo FOC-1 completes thermal vacuum testing; Global SatNav augmentation systems draw closer together; Article reformatted for milestone clarity; Extensive research links updated & upgraded; Appendix with project history details revised and restored; Full 2003 - 2014 timeline added.
The USA’s Global Positioning System service remains free, but the European Union is spending billions to create an alternative under their own control. In addition to civilian GPS (the Open Service), services to be offered include a Safety of Life Service (SoL) for civil aviation and search and rescue, a paid Commercial Service with accuracy greater than 1 meter, plus a Public Regulated Service (PRS) for use by security authorities and governments. PRS/SoL aims to offer Open Service quality, with added robustness against jamming and the reliable detection of problems within 10 seconds.
Organizational issues and shortfalls in expected progress pushed the “Galileo” project back from its originally intended operational date of 2007 to 2014/15. After a public-private partnership model failed, the EU gained initial-stage approval for its plan to finance the program with tax dollars instead of the expected private investments. Political issues were overcome in 2007 by raiding other EU accounts for the billions required, but by 2011, it became clear that requests for billions more in public funds were on the way. Meanwhile, doubts persist in several quarters about Galileo’s touted economic model. Security concerns regarding China’s early involvement, and its potential Beidou-2/Compass projects, have been equally persistent, and there is good reason to expect that the constellation has a military purpose. On a European political and contractual level, however, Galileo is now irreversible.
This article offers background, players, developments, contracts, and in-depth research links for Galileo, as well as linked EU programs like GIOVE and EGNOS.

Latest updates[?]: New launcher could open a whole new market by making Javelin a popular choice for naval vessels, from small patrol boats to large surface combatants.
The FGM-148 Javelin missile system aimed to solve 2 key problems experienced by American forces. One was a series of disastrous experiences in Vietnam, trying to use 66mm M72 LAW rockets against old Soviet tanks. A number of replacement options like the Mk 153 SMAW and the AT4/M136 spun out of that effort in the 1980s, but it wasn’t until electronics had miniaturized for several more cycles that it became possible to solve the next big problem: the need for soldiers to remain exposed to enemy fire while guiding anti-tank missiles to their targets.
Javelin solves both of those problems at once, offering a heavy fire-and-forget missile that will reliably destroy any enemy armored vehicle, and many fortifications as well. While armored threats are less pressing these days, the need to destroy fortified outposts and rooms in buildings remains. Indeed, one of the lessons from both sides of the 2006 war in Lebanon has been the infantry’s use of guided missiles as a form of precision artillery fire. Javelin isn’t an ideal candidate for that latter role, due to its high cost-per-unit; nevertheless, it has often been used this way. Its performance in Iraq has revealed a clear niche on both low and high intensity battlefields, and led to rising popularity with American and international clients.
