A fully operational constellation with global coverage consists of 24 satellites, while 18 satellites are necessary for covering the territory of Russia. which will use modulation similar to modernized GPS, Galileo, and BeiDou. Glonass-K consist of 26 satellites having satellite index 65-98 and widely used in Russian Military space.

When Galileo, Europe's own global satellite navigation system, is fully operational, there will be 30 new satellites in Medium Earth Orbit (MEO) around the Earth at an altitude of 23 616 km. Ten satellites will occupy each of three orbital planes inclined at an angle of 56° to the equator (see diagram). The satellites will be spread around each plane and will take about 14 hours to orbit

The L1-SAIF signal at 1575.42 MHz is fully compatible with the GPS-SBAS and WAAS system while the L-EX signal at 1278.75 MHz provides a high-data rate signal (kbit/s) and is compatible with the E6 signal band of the European Galileo satellites - allowing QZSS to serve as an augmentation constellation for both GPS and Galileo.

GpS became fully operational. As GpS approached that status in the early 1990s, civilian and commercial users,who already had 10 times as many GpS receivers as the and europe pressed hard toward launching the Galileo satellite navigation system.Whether all those capabilities could be melded into a fully integrated Global navigation
In the second step (2006-2011), the system would be brought to fully operational status with 24 satellites, and another, smaller and more accurate satellite design, GLONASS-K would be introduced. This would make GLONASS compatible with GPS, GALILEO and Compass receivers, which also use the CDMA method. A GPS is considered to be a Global Navigation Satellite System (GNSS) — meaning it is a satellite navigation system with global coverage. As of 2020, there are two fully operational global navigation satellite systems: the U.S. navigation signal timing and ranging (NAVSTAR) GPS and Russia's Global Navigation Satellite System (GLONASS). Galileo: en route to full operational capability. Date : Fri, Nov 26, 2021 | 07:30 - 09:00 GMT | 08:30 - 10:00 CET. Replay : Fri, Nov 26, 2021 | 16:00 - 17:30 GMT | 17:00 - 18:30 CET. Type: ESA TV Exchange. Soon another pair of Galileo satellites will be launched on top of a Soyuz from Europe spaceport in French Guyana. eKyi.
