260. Notes the Commission replies on the progress made in implementing the Galileo project: four Galileo In-Orbit Validation (IOV) satellites were successfully launched in 2011 and 2012, the Galileo In-Orbit Validation phase was successfully concluded in 2014, the system design, the performance targets and the baseline for system operation were successfully confirmed, the ground infrastructure, with many ground stations worldwide, has been completed for the initial operations, the Galileo Search-and-Rescue capability of the IOV-satellites was successfully demonstrated, the launch of two satellites (no. 5 and 6) on 22 August 2014 resulted ...[+++] in an injection of these satellites into incorrect orbit, and since December 2014 the satellites have been gradually moved to a more favourable orbit to allow their best possible use, and the testing of the satellites' navigation payload is on-going; expects to be informed about additional costs for these unforeseen measures;

40. Calls for the vulnerability of future European satellite systems to be reduced through anti-jamming, shielding, on-orbit servicing, high-orbit and multi-orbital constellation architectures;

Research will focus on: satellite interfaces, sensors, data, and system architectures developed in Europe or elsewhere, as well as developing a prototype of operational services responding to three specific types of orbits (Low Earth Orbit, Geostationary, Galileo orbital planes).

* increased availability of the space segment (27 medium earth orbit satellites on top of the four low earth orbit satellites and the three geostationary satellites in the current system).

In addition, the far northern areas of the earth are covered by satellites in a highly elliptical orbit (Russian molnyia orbits) in which the satellites are visible to users in the far north for half their orbit.
