According to the foreign media techcrunch, earth observation has developed from a task operated by the government into an important daily commercial tool, and it still has room for development. Specifically, it’s the thermal infrared spectrum – if the start-up satellite Vu gets into orbit. The company plans to monitor thermal signals from most buildings on earth through satellite constellations built for this purpose. Anyone who knows exactly how much heat is emitted from buildings, fields and other buildings has a huge market, according to Anthony Baker, co-founder and CEO of satellite vu. < / P > < p > heat may mean poor insulation and also energy waste of HVAC. It can show the real (not reported) operating time of a plant or mine, and it can track burned natural gas or refinery emissions. It has a resolution of 3 to 4 meters, and can even estimate the number of people attending outdoor activities or the concentration of troops in war. Of course, it can do it in the dark. < / P > < p > Baker told the media techcrunch that despite the success of the earth observation business like planet, there is still a lot of room for development. “Planet and Google maps, they can tell you what’s going on outside the building. We can tell you what’s going on inside. ” There are new and old technologies behind it. Although infrared detection can be traced back to decades ago, it is a very different proposition to detect a distance less than one degree from orbit. Satellite Vu was originally developed by Oxford University for the lunar trailblazer orbiter to find water on the surface of the moon. < / P > < p > Baker said they used sensors, hardened them in space, and did all the “new space” work, such as miniaturization and power optimization, but the problem with making the device smaller and more efficient was that it would affect the image, so they found a way to solve this problem. Satellite vu is understood to have followed apple, Google and others. As they try to improve smartphone cameras, these companies find that when there is little to improve the hardware, they need to focus on software. < / P > < p > like technology companies, satellite Vu’s system collects information from dozens of consecutive images and then parses it into an improved image. < / P > < p > “we stack the images together and get higher resolution to eliminate aberrations and many other things. These are all patentable. ” Baker added. < / P > < p > and the result is a very cheap satellite: the company can achieve about $15 million of satellites for just $7 to provide global coverage. To facilitate comparison, Baker said that ESA has just approved a 500 million euro project to collect thermal images with a resolution of 30 meters (the smaller the better). < / P > < p > although the competition in the field of earth observation is very fierce, there is almost no competition in the commercial space in this special niche field. The planet’s satellite can see the near-infrared spectrum, but that’s not enough to get detailed heat data. There are military satellites, there are also some from NASA or ESA that can do this, but they are often old, special-purpose, classified, or a combination of all three. It is impossible to obtain conventional thermal images of the orbit from commercial suppliers. UAVs and high altitude flight are an option, but they are not the same thing as satellites. While some start-ups want to move into the same field, each participant may have room for growth. < / P > < p > in response, Baker said: “it attracts a lot of people and government agencies around the world want to find commercial sources for this data. The simplest markets are probably ESG (environment, society and Governance) and green finance. Everyone is investing in green materials and stocks, but how do you know they are green? There’s no one to calculate. But we can measure it. ” More Samsung devices can now run Android applications on PC through your phone
