The GPS faces in April to its particular effect 2000



They will be obliged to carry out a transition in the date format just as it happened at the end of the last millennium



 On April 6, GPS devices face their particular effect 2000 and manufacturers of GPS devices work for a transition that entails certain risks.

The first week of April, these devices will have to make a transition in the date format they use to measure time, because the measurement system that is still used, inherited from its origins in the seventies, reaches limit of weeks you can count.

  The method was born in the 70s in the United States for the military, but is currently one of the most widespread geolocation systems in the world, used to regulate land, air and naval traffic, among others.

The GPS system uses the satellite network as a basis for the positioning of the devices. However, the communication with the satellites is not in danger, since the communication is unidirectional, and it is only the satellites that transmit signals to the devices, and not vice versa.

The temporary GPS standard has a maximum of 1024 weeks due to its 10-bit system established in its development in the seventies, which translates into 19.7 years, after which there is a change of era.

In August 1999 the first restart of the GPS WNRO (Week Numer Rollover) was carried out and the next one is scheduled for this April 6th. The problem will affect units more than eight years old, for which there is no solution, according to Tom Tom.

The most modern must update their software for free through the Internet to continue operating normally. A global failure of the Global Navigation Satellite Systems (GNSS) global navigation system, of which the GPS is part, would cause an impact of 6,000 million euros in five days and only in the United Kingdom.

92% of Spaniards connect to the internet at least once a day Half of the world's population is connected, reaching more than 4,000 million mariners    For the first time in history, the Network of networks reaches 4,021 million people who browse it, a figure that assumes that the Internet reaches half of the world's population, according to data from the Digital report in 2018 by Hootsuite. and We are Social. An increase in users who also move to Spain, where the figure has grown by 2 million to reach 39.4 million active Internet users , which means that 85% of Spaniards already have access to the network. "With 4,000 million online users, connectivity has already become a way of life for most of us. However, while Internet companies strive to provide service to the next billion users, we will see important changes in the coming months, "says Simon Kemp, global consultant at We Are Social.    According to the Digital 2018 report, Spaniards spend 5.20 hours a ...

Autonomous boats will arrive in Europe in 2017

Autonomous boats will arrive in Europe in 2017 The waters of the canals of Amsterdam will receive the first robots ships    If the autonomous cars begin to accumulate kilometers by the highways of the United States, to the other side of the Atlantic Amsterdam prepares to receive the first boats without captain. "Imagine a fleet of autonomous boats for the transport of goods and people," Professor of the Massachusetts Institute of Technology Carlo Ratti said in a statement from this research center. The Amsterdam Institute for Advanced Metropolitan Solutions is working on a project that will culminate in 2017 with the first trips through the capital's canals with robot ships.   The scientific director of the Dutch center, Arjan van Timmeren, said that these boats "offer enormous possibilities" and could have application in environmental and health issues, such as detecting diseases in advance once progress is made in relation to underwater robots. The project wil...

Artificial intelligence takes over the drones

Artificial intelligence takes over the drones An MIT mapping system allows unmanned aircraft to dodge obstacles at low speed     Can a drone only dodge an obstacle? The answer is yes. The Laboratory of Computer Science and Artificial Intelligence (CSAIL) of the Massachusetts Institute of Technology has managed to provide artificial intelligence to a small aircraft to fly through forests and warehouses. Nanomap, the new alternative navigation system allows you to fly over and avoid obstacles, as long as the speed of the device does not exceed 30 kilometers per hour.    Excessively safe maps will not help if you want drones that can operate at higher speeds in human environments," says graduate student Pete Florence, lead author of a new related document. "An approach that is more aware of uncertainty gives us a much higher level of reliability in terms of being able to fly close and avoid obstacles ." Shocks Many existing approaches are based on complex ...
