Global Navigation Satellite System (GNSS) – What is it?

GNSS stands for Global Navigation Satellite System and is an umbrella term that encompasses all global satellite positioning systems. This includes constellations of satellites orbiting over the earth’s surface and continuously transmitting signals that enable users to determine their position. The four major global GNSS systems are – GPS (US), GLONASS (Russia), Galileo (EU), BeiDou (China). In addition, there are many regional navigation systems which are being developed by various countries.

These systems give essential capabilities to civil, military, and commercial users all over the world. These signals are liberally available to anyone with a GNSS receiver. Be it a mobile phone, handheld GPS unit or SatNav, it can sense and obtain the radio signals that these satellites broadcast.

How it works?

When a GNSS is tracked, it implies to be a method of identifying where exactly an element is situated. A GPS tracking system, for example, can be placed on a cell phone, in a vehicle, or on distinct GPS devices, which can either be a stationary or portable unit. Hence, it can also trace the movement of a person or vehicle. So, for instance, a GPS tracking system can be utilized by a company to oversee the route and movement of a delivery truck, or even to monitor & observe high-valued assets in transit.

The GNSS network integrates an array of satellites that utilize microwave signals that are transmitted to GPS devices to provide information on location, speed of the vehicle, direction & time. Basically, a tracking system can possibly provide both historic and real-time data on any kind of journey.
While GNSS satellites vary in age and design, their principal operation remains the same. The satellites transmit two carrier waves in the L-Band referred to as L1 and L2. The carrier waves transmit information from the satellite to the earth.

Most GNSS receivers have two parts — antenna and processing unit. The antenna receives satellite signals while the processing unit makes sense of it. To determine the position of the receiver it needs to collect information from a minimum of three satellites.

Use of GPS from a military perspective!

Global Positioning System (GPS) is one such technology, where the emergence of the space age has led to the advancement of several technologies, discovering its extensive purpose both in military and civilian fields. Military forces, all over the world are utilizing GPS for diverse applications, both throughout wartime and peacetime. These comprise navigation, targeting, rescue, guidance, & facility management. For instance, with war clouds approaching over a certain area like Asia, the US led forces have always portrayed to use weapon systems, which profoundly rely on GPS for their lethality and accuracy.

GNSS helps track or guide GNSS enabled devices such as vehicles, military systems, UAVs, missiles, etc. It can facilitate civil protection operations in harsh environments, speed up rescue operations and help coastguard and border control authorities in navigation through unknown territories. Success of new age security operations depend upon the ability to navigate correctly to the target locations. However, GNSS can also be used by subversive elements to navigate UAVs to deliver explosives or to take photographs of restricted/protected areas or to control guided missiles.
