Real-time satellite data is a trendy concept and a question that our customers sometimes ask. But real-time satellite data is not what you think it is. As with most high-quality feeds, limitations on data refresh come from transfer speeds and processing speeds. In best-case scenarios, it could take only a few minutes between data capture…
AI in space is not just for government officials or the military; it’s available to anyone looking to access it. At 精东影业, we believe in simplicity. We鈥檝e taken a very challenging data engineering problem – obtaining, processing, and standardizing satellite data – and built a platform that abstracts the massive amount of complexity required to…
Let’s break down data transfers. Satellite data collection is extensive, with some of the latest high-resolution optical and radar readings gathering gigabits of information each second. The issue lies in sending this data back to Earth, an act known as a downlink. Unfortunately, current technology has these downlinks occurring on sun-synchronous orbits at limited points…
Understanding how satellite images are created begins with sensors. Satellite sensors, unlike our eyes, capture much more information and relay it back to us in a format quite different from the photographs we are used to. Satellites capture data by assigning a digital value to each pixel based on the reflectance of the corresponding area…
Sun-synchronous low Earth orbits Understanding orbits is simpler than one might think. In the same way as consumer cameras, the closer you are to the object you want to capture, the more details you can see. Satellites in Low Earth Orbit (LEO) can capture images of high resolution because they are closer to the object…
Multispectral and hyperspectral satellites A sensor’s spatial resolution, or how fine the pixels on the ground will be, is inversely related to its spectral resolution or how well it can discriminate between spectral bands. Because of this, satellites that record data along multiple spectral bands (hyperspectral) do not have the same spatial resolution as satellites…
According to Euroconsult, the global market for commercial Earth observation data and services will reach $8 billion by 2029, up from $4.6 billion in 2019. Understanding when to use satellite imagery over drones is key to making an informed decision when collecting this data type. Here are 5 benefits of using satellite imagery over drones…
Colors are just how our eyes interpret light. Light is made of electromagnetic waves. When light shines on an object, some wavelengths are absorbed and others are reflected. The colors we鈥檙e able to see are just a small range of reflected wavelengths that can be perceived by our vision. They consist of a tiny visible…
A remote sensing device, such as a satellite, collects and acquires physical, chemical, and biological information about the Earth. This blog aims to explain how satellites can detect invisible radiation to the human eye. Then, GIS professionals can use various techniques to extract insights from the composite image. For example, a satellite image can visually…
A group of Canadian high school students, advised by physics teacher Joe Muise, is from St. Thomas More Collegiate in Burnaby, British Columbia, is poised to represent Canada at the ESA’s CanSat competition this month.
