GLONASS an acronym that stands for Globalnaya Navigazionnaya Sputnikovaya System or Global Navigation Satellite System. GLONASS the Russian version of GPS (Global Positioning System).
Who built GLONASS?
The Soviet Union began developing GLONASS in 1976. GLONASS is the most expensive program of the Russian Federal Space Agency, which consumes one third of its budget in 2010.
The various versions of GLONASS are
- GLONASS – launched in 1982, the launched satellites were intended to work for meteorological positioning, speed measurement and timing anywhere in the world or in space close to Earth by military and official organizations.
- GLONASS-M – launched in 2003 adds the second civil code. important for GIS mapping receivers.
- GLONASS-k – started in 2011 still has 3 more types: k1, k2 and km for research. Adds third civil frequency.
- GLONASS-K2 – will be launched after 2015 (currently in the planning phase)
- GLONASS-KM – will be launched after 2025 (currently under research)
What is A-GLONASS?
A-GLONASS, Assisted GLONASS very similar to GLONASS but A-GLONASS offers more functionality for smartphones. It offers features such as turn-by-turn navigation, real-time traffic data and more. Use the cell towers near your location to quickly lock your location with the help of your data connection. A-GLONASS also improves the performance in the chip sets supplied with GLONASS support.
How much did GLONASS cost?
Until 2011, the Russian government has spent approximately $ 5 billion on the GLONASS project and has invested an additional 320 billion rubles ($ 10 billion) for the 2012-2020 period. GLONASS the most expensive project ever carried out by the Russian Federal Space Agency.
How does GLONASS differ from GPS?
The GPS developed by the United States has a network of 31 satellites covering this planet and has been widely used in commercial devices such as cell phones, navigators, etc.
GLONASS developed by Russia originally founded by the Soviet Union in 1976. It has a network of 24 satellites covering the earth.

Here is a table of specifications that compare GPS vs GLONASS
|Owner||Russian Federation||United States|
|Number of satellites||At least 24||31|
|Orbital height||21150 km||19130 km|
|Precision||Position: 5-10 m||Position: 3, 5-7, 8 m|
|Inclination of the orbital plane||64, 8 degrees||55 degrees|
|Orbital period||11 hours and 16 minutes||11 hours and 58 minutes|
|Frequency||Approx.1602 GHz (SP) Around 1,246 GHz (SP)||1.57542 GHz (L1 signal) 1.2276 GHz (L2 signal)|
Advantage of GLONASS on GPS (GLONASS Vs GPS)
There is no clear advantage other than accuracy on GPS. When used alone, GLONASS does not have coverage as strong as GPS, but when both used together they certainly increase accuracy with coverage. And more useful in the northern latitudes as Russia started GLONASS originally for Russia.
Precision is an advantage of GLONASS with precision up to 2 meters. GPS + GLONASS allows you to point your device on a group of 55 satellites worldwide. So when you are in a place where GPS signals are blocked like between huge buildings or subways, you will be tracked accurately by GLONASS satellites.
Commercial use of GLONASS
GLONASS was the first commercially used in car navigators such as the Glospace SGK-70 but it was bulky and expensive. The Russian government is trying hard to promote GLONASS commercially.
iPhone 4S was the first Apple product to use both GPS and GLONASS to locate the location on maps.
All high-end devices that support GPS functionality, especially navigators, include GLONASS receivers on their chip to use location-based services.
What is offered for smartphones?
Today any mobile phone, whether it is a high-end smartphone or a low-cost smartphone, equipped with A-GPS (assisted Global Positional System) that uses the network capabilities to find its position.
Now with GLONASS offered for public services, more and more smartphones are launched with GPS + GLONASS technology to use the location-based dual core service to find the location. Initially only Flagship or high-end smartphones boast these features, but over time, we will see both of these technologies equipped on low and medium-end smartphones. More and more chip companies and manufacturers seem to be interested in GLONASS technology, so more and more smartphones are expected with this technology.

How does Google Maps use GLONASS and GPS?
Google Maps and other mapping applications such as Nokia HERE Maps and Apple Maps use the data connection to connect to the GLONASS and GPS satellites. Modern smartphones are equipped with A-GPS and A-GLONASS support, which offers features such as turn-by-turn navigation, location tracking and real-time location information.
What are the prospects after GLONASS and GPS?
- The European Union is currently working on a system called GALILEO which provides a highly accurate global positioning service under civilian control. The Galileo system consists of 30 satellites (27 operational + 3 active spare parts), positioned in three circular planes of average Earth orbit at 23 222 km above sea level and with an orbital plane inclination of 56 degrees with respect to equator.
- China is developing its own constellation of 35 satellites called BeiDou Navigation Satellite System and under construction since January 2015. Offer more capacity than current GPS. currently operating in China and the Asia Pacific region with 11 satellites in use, it will be available globally by 2020.
- IRNSS o Indian Regional Navigation Satellite System an autonomous satellite system developed by the ISRO (Indian Space Research Organization) and offering public service and limited service (authorized users as military). This system would consist of a constellation of 7 satellites, 4 of which are already positioned in the orbit. The project is expected to be operational by 2016.
