Can satellites see you at every moment?

The number of satellites orbiting our planet is increasing dramatically and capturing images of what is happening in the earth with dazzling clarity. In 2008, there were about 150 commercial satellites in service, and now there are 768.

At this time, businesses can’t take pictures of the same place for 24 hours, but it may be possible in a short time. Associations for the protection of personal freedoms say that the growing number of satellites and the development of imaging techniques is very frightening and violates the personal freedom of community members.

These organizations are sounding tougher alarms to impose tighter controls that restrict any company that wants to launch a satellite for commercial purposes. else.

Pictures taken will, of course, become clearer

Today’s commercial satellites provide high-resolution images that are sufficient to see cars, but without distinction of their type and plate number.

U.S. laws limit the accuracy of satellite imagery to 25 centimeters, meaning it is impossible to distinguish details of anything smaller than this size, and of course not about military spy satellites.

In 2014, NOAA increased the permissible accuracy of satellites from 50 centimeters to 25. This accuracy is more than sufficient for commercial use, such as monitoring oil supplies in collecting tanks, flooding to protect crops and monitoring displacement in affected countries.

History of commercial satellites

The first commercial satellite for DigitalGlobe, owned by Maxar Group, was launched in 1997. Planet Labs alone owns 140 satellites, allowing it to film every point on Earth at least once a day. BlackSky Global says its satellites will be able to pass over major cities more than 70 times a day.

All companies working in this field seek access to live broadcasting service in high resolution of the Earth and around the clock, but we are far from this goal, which seems impossible shortly.

Clouds may obscure visibility from conventional satellites, but NASA has found the solution since the 1970s: electromagnetic waves using microsatellites in satellites, which can observe objects as long as one meter long. Nearly 50 years after the United States acquired these technologies, last year it allowed the use of electromagnetic radars for commercial purposes.

The future of satellites

Over time, the commercial accuracy of satellite imagery will increase, and large companies will press their full weight to increase the allowable resolution to 10 centimeters. Despite severe restrictions on companies, a Chinese company takes 10-centimeter photos and sells them all over the world for a lot of money.

Our freedom is at stake without satellite images

Satellite companies say they are keen to secure their data and hide the identity of people who appear in the images, but new technologies and their great harmony can violate the privacy of users regardless of satellite images.

Day after day security cameras and location services such as GPS and social networking sites are increasingly spreading, all of which can accurately track your movements without your knowledge, where are you now? To which school do your children go? What types of stores do you go to? What religious institutions do you visit?

Satellite is a double-edged sword

All types of technology are a double-edged sword, which can benefit us a lot but at the same time are very dangerous, and may lead to disasters that were not counted. In the last year 2018, a Russian company hid sensitive military sites in some countries, which aroused the curiosity of users around the world and began to compare the images were modified with images taken from other companies, and as a result, the whereabouts of all those points that were supposed to be secret were revealed.

The only solution

The price could be our only savior. Each new technology has very high costs. Observers say launching a set of satellites that can shoot Earth at a resolution greater than 25 centimeters and around the clock is expensive, and profits cannot cover the cost with little demand for these services. , And because of the high price of satellites and their launch costs.

Alternative solutions for satellites

Many companies requiring higher resolution images use drones to monitor major projects, and despite the availability of this technology in our hands, the laws of some countries such as the United States of America require the authorization of aircraft weighing more than 227 grams, but it is different in space. States have free access to space under the Outer Space Treaty of 1967.

The future may bring a lot of surprises. The costs of producing and launching satellites may fall, and the demand for such services may increase.
