Galileo positioning system

Satellite has provided major changes in the modern technology. It is truly an amazing fact that satellite is the creation of the technology, and satellite itself is the leader of the modern technology. Truly, it is a great achievement of the human civilization that satellite is now the key source of the modern advancement of the civilization. Now one great achievement with the satellite system is the Galileo (positioning system). Actually, Galileo is the global navigation satellite system of the European continent. With this navigation system, you can perform a lot of work. The key work or task of this system is to provide the accurate global positioning. This system works with the civilian control; that means civilian control is the receiving authority of this system.

Facts about the Galileo:

Key features: One key feature of this system is it works with the GPS and the GLONASS. Glonass is the navigation systems of the USA and the Russia. Now, one important fact regarding the GPS is that this GPS must be the interoperable one. With dual standard frequencies, Galileo always delivers the accurate positioning.

The number satellites prepared so far: Four satellites were prepared for the Galileo global navigation system. In two phases the satellites were placed in the right place. In 2011 on 21 October, first two satellites were activated to provide equal operations, both in space and on the earth. The next two satellites were activated in 2012 on 12 October.

Important phases: After a thorough experiment the IOV phase or the “In-Orbit Validation’ phase is the key or the main phase of the operation of the system. With this phase, one additional phase is also added that is “FOC” or the “Full Operational Capability.” Till today four pairs of the “Full Operational Capability” satellites were launched on 22 August in 2014, in 2015 on 27 March, in 2015 on 11 September and in 2015 on 17 December. All the satellites were launched from French Guiana by Soyuz.

This satellite navigation system is one of the unique examples of the human creation. Truly, Galileo is now a great discovery, and with this, a new definition of the global positioning system is invented.

Services provided by the Galileo: the complete Galileo satellite global navigation system consists of the 24 satellites. All the 24 satellites should be operational satellites. These satellites are positioned in three MEO or the Medium Earth Orbit. It maintains 23222 km altitude just above the earth. The accurate positioning of the satellites truly discovers a whole new dimension of the navigation system.

The service of this system will be active at the end of 2016. But with the activation of this system, at first, the operation will be thoroughly tested, and at the same time, the complete service will be available in 2020.

The design of this system is unique. Beautifully optimized these satellites are designed like a constellation. Each orbit plane will have three active spare satellites, and this helps to maintain the active satellite system. Truly Galileo is a great achievement of the human civilization. One can’t ignore a fact that the proper navigation system is truly an accurate evidence of the human invention.

GPS devices

GPS or Global Positioning System is a common word.  If you are in a remote place or traveling in a completely unknown area, then GPS is the best friend to show your actual location and indicates the final destination that you actually need. It is a unique navigation system. And if you have a portable GPS device, then you can easily determine the location where you actually want to go. There are several key benefits of the GPS system.  Now there are different kinds of GPS devices available in the market, and different devices are applicable for different purposes.

Now the key question is how you can choose the best GPS unit that can satisfactorily serve your main purpose. It is always the priority that you should avail the best suitable GPS unit with the most affordable price.

There are some specific features that indicate the quality of a good GPS unit. Now, while choosing the best GPS unit, it is necessary that you must notice that your GPS unit can have those features.

Features to choose the best GPS unit:

The modern GPS unit can provide a huge number of features, like MP3 player, FM transmitter, and many others. But there are some specific points, which customers always take into consideration before selecting the best GPS unit.

GPS maps:  Most of the times a GPS device is preloaded with maps of the region from which you are purchasing the unit.  Though, the users always have the option to download the additional maps and other important programs.  These programs ultimately help you in your navigation in some new and unknown areas. The additional maps can be added to the unit by the manufacturer.

GPS Antennas: One key feature of a good GPS unit is the GPS Antennas. If you have these antennas on your device, then you can easily track down the proper location. This is mainly applicable for the urban areas. It is also useful for camping in a distant place. So, the key fact is cell phone tracker help to acquire a strong signal.

Bluetooth Capability:  With new and modern technology, the GPS unit can provide you hands-free Bluetooth facility. It actually works as the FM transmitter. It even helps you to receive traffic information while driving in a car. Now it is a fact that a GPS unit must have the Bluetooth feature, but the key point is whether this facility is equipped with the best technology or not.


Data Storage:  Data storage is one very important feature that you have to see before approaching for a good GPS unit. It is obvious that a good unit must have the facility to store data. But the key fact is you have to make it sure that to store more data you must have some extra facility that is a removable memory card. The memory cards are almost similar to the memory cards that are used in digital cameras. Now you can use a bigger memory card to store more data.

So, the above-discussed points show the key features that are very necessary for choosing the best GPS unit.
