GNSS: Knowing the Basics

In the current world dominated by mobile phones, applications and technology, it is no longer surprising that these little gadgets in our hands can do great feats that our ancestors from a century ago could only imagine. With just a click of a button or a swipe of a screen, we can order food or locate our sibling. This is made possible by our advanced technology. Through a series of intricate connections made through various networks and the internet, locating something or someone is readily available.

What is GNSS?

One such technology that makes locating, tracking and positioning an object possible is the GNSS. It stands for Global Navigation Satellite System. As of the moment, it is the standard generic term for the satellite navigation systems that provide autonomous geo-spatial positioning that covers the entire globe. Collectively, this would include terms such as GPS, GLONASS, Beidou, Galileo and other regional systems. It is very rare that these satellite systems would fail, but if one does fail, GNSS receivers can pick up signals from other systems. GNSS, when coupled with INS simulators, can efficiently and effectively locate, position and orient different objects.

How does it work?

Most receivers have two parts: the antenna and the processing unit. What happens is that the satellites transmit two carrier waves in the L-Band known as L1 and L2. These carrier waves then transmit information from the satellite to the earth. The antenna will then receive these signals, and the processing unit will decipher it. To determine a proper location, the receiver needs to collect information from a minimum of three satellites.

There are a number of GNSS satellites that orbit the Earth once every 11 hours, 58 minutes and 2 seconds at a medium-orbit altitude. Precise orbit details and time stamps are coded from the signals that the satellites transmit.

GNSS Products

Frequency GPS Simulator

With technology being this advanced, it is only fitting that consumers can identify what kind of products would be useful for them in their daily lives. Various companies and establishments provide Inertial Navigational Systems that work well with GNSS INS Simulators. These products would all be useful in various aspects of human life such as in autonomous navigation, surveying, motion analysis and pointing and stabilization. For autonomous navigation, this is used in drive-less cars, industrial machines and many others. The INS provides real-time roll, pitch and heading that would provide a robust and reliable location of the vehicles in question. In surveying, mobile mapping is made possible for land, air and marine locations. For motion analysis, this is rather useful in Heli-decks, ship racing and monitoring. For pointing and stabilization, this is rather useful in gimbal cameras to provide steady and stabilized photos.

Make sure that upon purchase of these products, proper orientation and training is performed. For some companies, they can provide 2-hour courses once INS GNSS simulators are purchased. This is to ensure that no mistakes would occur. Remote access tutorial with an engineer is possible for some companies.

Training should be flexible, and clients should be able to determine whether it should be done on the facilities of the company or at a location determined by the client. It is also impeccable that GNSS inertial navigational systems installation, commissioning, integration and services be done for all the clients.

Conclusion

The Global Navigation Satellite System is but one of the various systems that make our current world a single-button world. All these are made possible so that our lives are made easier as we go about with our day to day lives.
