Are we nearing the end of the Global Positioning System (GPS) monopoly?


The world of drones will become more and more technologically advanced. The latest news, which we will also talk about, seems like the perfect excuse to do a little work disclosure of information about global positioning and navigation systems and thus a much better understanding of how close we are to the end of the monopoly of the GPS system.

GPS vs. Galileo

We have no doubt that you know the GPS system. The vast majority of cell phones include it. System GPS It currently has a monopoly on satellite navigation, but it is American-made, designed for military use, and remains under full US control.

Galileo on the contrary, it is a European system for civilian use. Once completed, it will be more accurate than the system GPS and that the Russian system Glonass. With the exception of Galileo, all other systems are intended for military use.

The following video illustrates all of these issues quite well.

Global Navigation Satellite System (GNSS) Brief Overview

We are talking about the unification of various systems into a single constellation of artificial satellites of our planet and which allow determining the geographic coordinates and height of a given point as a result of receiving their signals. It’s no exaggeration to say what that will mean the end of the monopoly of the GPS system.

These systems are certainly of great interest to us in the context of drone navigation, but their interest extends beyond the drone context and even the general aviation context as it also affects land and sea navigation capabilities. System GPS American, Russian system glonass, and European Galileo compete for a market of more than 135,000 million euros. to see http://www.infoespacio.com/es/2017/07/25/noticia-navegacion-europea-front-glonass.html

the Chinese system Beidou it seems to have been forgotten in the link we just gave, but the point is that all these systems revolve around our planet and that the size of the economic pie they want to share is very significant.

GNSS can use different satellite systems such as GPS, GLONAS, Galileo, BeiDou and integrate them into a single advanced positioning system.

This is just the beginning, and as the receiver market for various positioning systems offers us new opportunities, someone might be interested in taking a look at the EOS GNSS system. «How to Use Four Constellations for Submeter GNSS Mapping: GPS, Glonass, Galileo, BeiDow»

A bit of Spanish news regarding drones and GNSS.

Interesting news was published aerospacenews.com: we learned that “testing to standardize drones with systems is coming to an end GNSS Europeans»

Project tests EGNSS4RPAS for the standardization of art DPAS at the European level, they were held in Spain. Specifically in Villacarillo, in the province of Jaen. For urban scenarios, it was necessary to introduce a parachute system into the drone.

The purpose of these tests was to evaluate the performance of European navigation systems (Galileo I EGNOS) in relation to drones.

The European Commission intends to demonstrate that these European systems can provide added value to the equivalent US GPS system. For this, a highly accurate receiver was used in each drone.

In particular, it is considered possible air traffic control applications or applications in urban scenarios such as the delivery of small parcels or emergency medical products, or in the inspection of buildings and infrastructureetc.

Test results

Tests show that Galileo offered a better response than the American GPS system, and that the corrections made by EGNOS improved the accuracy provided by GPS to below one meter.

360 aerial video of Salinas de Imon

We offer the ability to record video from the air in 360 format As we already assumed in a previous post we were delighted to participate in the technical marketing event hosted by MarketingDirecto.com where we first introduced our new service 360º aerial photography using a drone : a type of video that comes with a number of benefits as well as challenges. Advantages of aerial photography in 360 On the one hand, it makes a difference immersive 360º videos offering something entirely new as the experience of putting on virtual reality glasses and contemplating a Video from the air 360 To date, this is one of the closest sensations to the feeling of flying like a bird. It is also an incredibly beautiful and attractive way to display and promote tourist attractions. Problems with video from the air in 360 On the contrary, creating this type of video adds the individual complications of getting the drone up in the air and recording 360-degree video, the biggest challenge is developing...

Purchase and use of parachutes for drones

The new law will allow working in conditions that were previously illegal. One operational scenario that has been most needed is flying drones in urban areas or over crowds of people, and this will be possible with a few requirements. One of them, the one that drives most operators crazy, is that the drone has an impact energy absorption system (airbag or parachute). The problem with this is that AESA has not yet decided on the specifications that these devices will need. Logically, it is about introducing a new element for improvement aviation security in the use of drones, but in this case the indications for use are not very clear. The subject seems delicate and following the rules can be costly. We will comment on the current situation and how DronProfessional.com is handling it A parachute is a good item to minimize damage in case of accidental drops of the drone. They help minimize damage to aircraft, cameras and LiPo batteries. The latter can become dangerous, as they ...

Análisis del incidente con drones en el aeropuerto de Gatwick

4.7/5 – (8 votos) Sin duda este no es el primer incidente entre drones y aviones, pero este último ha provocado un caos brutal durante nada menos que 24 horas en el aeropuerto de Gatwick en Lontres y por ello marcará necesariamente un antes y un después en la historia de los drones y en la gestión de los aeropuertos. ¿Por qué este incidente marcará un antes y un después? Los aeropuertos no pueden permitirse el lujo de sufrir este tipo de incidentes y adoptarán toda clase de medidas para poder dar respuesta a cualquier imprevisto de esta clase. La seguridad aérea está formada por un conjunto de medidas encaminadas a evitar los incidentes en todo tipo de aeronaves. En ese sentido, cada incidente grave se ve acompañado a posteriori de una ingente labor de investigación para determinar las causas de cada accidente aéreo. El objetivo de todo ello es incorporar nuevas medidas en los procedimientos operativos y en el entrenamiento de pilotos para evitar en la medida de lo posible nuevos acc...
