Galileo's new High Accuracy Service will provide free precise point positioning (PPP) corrections, in the Galileo E6-B data component and by terrestrial means, for Galileo and GPS (single and multi-frequency) to achieve real-time user position improved by up to 10 times. The infrastructure to support an initial service (Phase 1) is nearing As of 2012, the system was scheduled to have 15 satellites operational in 2015 and reach full operation in 2020 [needs update] with the following specifications: 30 in-orbit spacecraft (24 in full service and 6 spares) Orbital altitude: 23,222 km (14,429 mi) The Indian Regional Navigation Satellite System (IRNSS), which is being developed for positioning services in and around India, is the latest addition to the global family of satellite-based navigation systems. As IRNSS only shares the L5-frequency with GPS, the European Galileo, and the Japanese Quasi-Zenith Satellite System (QZSS), it has at least at present a limited interoperability with As of 2012, the Navstar Global Positioning System (GPS) of the United States and the Global Navigation Satellite System (GLONASS) of the Russian Federation are the only fully operational global GNSS. The European Union's Galileo positioning system is a GNSS in the initial deployment phase, scheduled to be operational in 2014. Besides existing operational global positioning systems i.e. GPS and GLONASS, another two have already emerged: GALILEO and Compass/Beidou. Alternatives to GPS imposed the GNSS concept, which has crystallized in a short time. The true reasoning of this excessive need for positioning information is beyond the scope of this paper; instead, an Details of the Russian GLONASS and the European Galileo systems are not included as they arrived later, and generally mimicked the GPS development albeit with their own, locally developed detailed designs. when GPS was approved for full-scale development. Between that time and the date that GPS was declared fully operational, April 27, 1995 Galileo: en route to full operational capability.
