Image correction

Many NewSpace missions place several instruments on a single satellite. Using multiple identical instruments, like VNIR pushbroom cameras, you can increase the effective swath width. If you use different instruments together, you can collect more types of data from the same place at once. It is difficult to align these sensors perfectly. Why is geometric alignment difficult? Earth observation satellites rely on two types of sensors to geolocate imagery on the ground. GNSS (su

In the previous two posts in this series, we discussed the sources of geometric and radiometric anomalies and how FarEarth corrects for them. In this blog, we share tips to make your mission a success. Accurate satellite attitude control Smaller satellites are agile. Your satellite will change orientation and frequently capture images from almost anywhere on Earth, even when not flying directly over the area of interest (AOI). The first hurdle is pointing the satellite cor

Let us look at how the FarEarth platform compensates for anomalies. FarEarth addresses corrections in different phases of your mission and at different stages during processing. Read the previous blog , where we discussed anomalies in Earth observation missions. Pre-launch We recommend that you test your camera to obtain a series of lab test datasets before you launch. These datasets help us to identify any potential issues with your imager. Common issues include faulty det

Behind every Earth observation (EO) mission is a team of scientists ensuring consistent, accurate image quality over time. No satellite sees Earth perfectly! Let us explore common causes of anomalies that must be accounted for in your mission. Most anomalies can be corrected with scientific calibration. Other anomalies will be random and unpredictable and will require engineering to compensate for. Physical causes The Earth is not round, but rather an oblate spheroid. The s
