Our lives being controlled by GPS

Our lives being controlled by GPS

The Global Positioning System (GPS) has been in control of our diaries. Just last month, SpaceX launched a GPS satellite into medium-Earth orbit on its Falcon 9 rocket. After a while, it will start giving you location signals.

With the help of which you can easily reach the place you want. Similarly, when you go to an ATM and withdraw money, all the details including where you withdrew money go to your bank. These details are coming through GPS Third Satellite (GPS III satellite). GPS is the newest member of Third Satellites.

Today, GPS has become important for almost all areas of the country's critical infrastructure, although much of its work is lagging behind the curtain, and probably to a greater extent than you realize. In simple language, GPS helps us to know where we are and where we are going.

It plays an important role in our daily transactions including financial transactions and stock trading, weather forecasting, earthquake monitoring.

According to a study released by the National Institute of Standards and Technology in June 2019, the economic impact of GPS in the United States is estimated at 1 billion per day.

In his book Pinpoint, published in 2016, Greg Milner wrote, "It is almost impossible to estimate the overall value of GPS. It is difficult to estimate the importance of GPS compared to other things.

However, GPS is only a small part of the global navigation satellite system. The world's most powerful nations are working to send better signals to the earth and to strengthen satellites.

This is good news for everyone, including the army, Uber drivers, pilots, bankers, geologists, farmers, drone users, self-driving cars. As the GPS system becomes more robust, it will make people's daily lives more comfortable.

How does GPS work?

There are 31 satellites in the GPS constellation, of which 24 satellites are spread over 6 orbits. Out of those 24, you are in touch with about four satellites at any time. Similarly, the other seven are essentially spinning.

Whether that satellite is using that signal every moment you pick up the phone on Earth or for other purposes, those satellites don't know where you are. Like a radio station in space, it only sends one-way signals.

Then your GPS receiver, which is a GPS chip on your phone or any other device, receives signals from four or more satellites. By measuring some of the differences that occur during the arrival of signals, within nanoseconds, it can calculate where you are and whether you are in motion.

Scott Burgett, president of Global Navigation Satellite Systems, says: All satellites send signals and they all match perfectly. However, your actual location depends on the time and distance traveled by the GPS satellite. '

The time of signal arrival depends on the latitude, longitude, and altitude as well as speed and direction. Based on this, Google Maps, Apple Maps, and other geographic information systems help us with information about how far it takes to reach our destination and how long it takes.

Euro Cup sets new record on Nepali internet

A big celebration is going on for football fans at this time. Due to the different games under the Euro Cup and Copa America at the same time, they are ready to schedule.

There are four games under Euro and Copa starting at 9:45 pm Nepali time till 7:45 am. Nepali football fans seem to be busy watching these games even if it is overnight. Such busyness of football fans has set a new 'record' on Nepal's internet.

The record-breaking day is July 15. On that day there were two round 16 games in the Euro Cup, between France and Switzerland and between England and Germany. In these two very competitive games, 17 goals were scored including penalties. When the first match between France and Switzerland started at 9.45 am, Nepal's internal internet traffic was on the rise.

According to Internet Exchange Nepal (NPIX), which measures internal internet traffic in Nepal, internet traffic reached 49.889 GB per second during the game. According to Rupesh Shrestha, chief executive chairman of the organization, this is the highest internet traffic in Nepal so far.

"During the Euro Cup, there was a tendency for traffic to increase at once and gradually decrease during the interval, and then increase again after the start of the game," he said, adding that "this is the highest record ever set."

Under normal circumstances, Nepal's internal internet traffic is 12 GB per second. However, the average has recently increased to 15 GB. Shrestha has the experience of increasing Nepal's internal internet traffic with the start of big football games.

"Even before this, the traffic had increased to 32 Gbps during the 2018 World Cup," he said. That was the previous record in internal internet consumption in Nepal.

According to Shrestha, internal internet traffic has also increased in recent times when service providers have been hosting internet content like Euro Cup in Nepal. On the other hand, it has benefited Nepal financially, he said.

"When hosting inside Nepal, when there is no international bandwidth consumption, a large amount of money is prevented from coming from outside," he said. He informed that the practice of hosting popular internet content in Nepal by keeping cache servers has been increasing recently.

He understands that the facility to watch television through Over the Top (OTT) has also strengthened it. Now users can watch television through apps like Dis Home Go, Net TV, Bhaya TV, Prabhu TV.

Internet service providers are also providing television facilities to their users based on the Internet. Shrestha argues that the trend of watching television through internet usage has also increased the traffic.

He said that this would ultimately benefit Nepal. NPIX evaluates Nepal's internal internet traffic based on data from its members. It currently has about four dozen members. Its members are the country's leading telecom and internet service providers, government bodies related to information technology, and hosting service providers.

Did the quality decrease when sending photos from WhatsApp? Now a new feature is coming

 WhatsApp is the most used messaging app worldwide. The app has been used extensively for personal as well as business conversations. Due to the end-to-end encryption feature available in it, users have been using WhatsApp as a secure medium.

On the other hand, this app is also considered useful for sharing video files. This is because WhatsApp reduces the size of the media file when sending it, so it is easier to go and download quickly. This feature of WhatsApp is also good in some ways. However, due to declining quality, many people do not like this feature.

So with that in mind, WhatsApp is now going to provide a new feature. According to Waveta Info, an organization that provides information about the beta version of WhatsApp, Facebook can now send photos via WhatsApp by selecting the quality.

The company has released this feature in the beta version. It is currently available to some users.

What you need to know to keep a secure password online

We are connected to various social networks as well as online platforms. Recently, the use of apps related to the banking business such as mobile banking and mobile wallet has been increasing. Passwords are essential to keep such apps safe.

If the password we keep is weak, others can access your account and make transactions. In the case of social media, they can take your information and use it illegally. Which can have a big impact on your personal and social life.

So keeping passwords and even keeping passwords secure is one of the most important issues today. That is why the Telecommunication Authority of Nepal, the regulatory body of the telecommunications sector, has been providing important information related to cybersecurity.

Based on the same information provided by NEA, here we are giving you information on how to secure your password.

Since it is not possible to memorize many passwords, keep your passwords secure using a trusted and reliable password manager.

Let's use the offline password manager as much as possible and keep a copy of it on other devices as well.

When using Online Password Manager, let's use Two Factor Authentication or Multi-Factor Authentication.

Let's use a strong password for Password Manager and remember that password. Also, use your mobile number or email for password recovery.

Let's not save the password in the browser. Disable the browser's Password AutoSave.

As it is not possible to memorize many passwords, passwords can be kept secure even by encryption.

Do not store/save the password in your email. Also, don't share with anyone.

If the website is insecure, Google Chrome will now notify you

Google is currently working on a new feature for Chrome, which will automatically instruct users to stay away from unsafe websites. Cram has introduced a new feature that provides information about websites that use HTTP instead of HTTPS.

Since 2018, Google has been emphasizing the use of HTTPS. Since then, it has listed sites using HTTP as unsafe. However, after Chrome 86 was unveiled last year, users were warned not to put their sensitive information, such as banking details, on insecure forms on the HTTPS site.

To address this issue, Google plans to add HTTPS-Only Mode to the next version of Chrome.

What is HTTPS - Only mode?

HTTPS-only mode prevents users from visiting any unsafe websites. Once this feature is available in Chrome, a toggle or option called 'Always use secure connections will be added to Chrome's settings.

It can be enabled in Chrome settings. This toggle will be available in the 'Advanced' option on the left side of the Chrome setting, which will need to be enabled.

Google will then upgrade the entire navigation to HTTPS, which will alert the user before loading any site. If a user visits a site by bypassing the HTTPS-only mode, Google will automatically save the site and not issue any warning when using the site again.

Google is still working on this and this feature will not be ready until version 93 or 94 of Chrome is made public. Google has said that these versions of Chrome will be available to the public by September.
