Why Are Images From СubeSat Cameras Important?

Apr 13, 2021

Many of the improvements that have improved human life are largely down to satellites, which have made it easy to connect different parts of the globe within a few seconds. We can navigate to various places within cities thanks to the help of satellites circling above the Earth. Yet, the most remarkable inventions in this category have come about only in the last decade or so. They are the CubeSat nanosatellite, which is essentially a tiny version of the satellites circling above the ground. One of the crucial accessories included in these new versions would be the CubeSat camera, which allows for a remarkable set of tools and advantages.

Due to the size being extremely small compared to a traditional satellite, it is possible to make a CubeSat camera at a fraction of the cost that it would take otherwise. If the regular route would end up costing several hundred million, this technology can be used to put an eye above the Earth at just around $40,000. It is a huge saving in a brief period. Furthermore, the deployment of many imaging solutions will also help.

The CubeSat Camera: Primary Advantages

Let’s discuss why photos taken from space with this kind of technology help the world.

In Agriculture

The CubeSat optical camera will provide considerable insight into the world of agriculture by monitoring crops and the input that goes into the same. The advantages are immense, as it is reported that a saving of around 10% can be achieved just in fertilizers. This can be made possible by monitoring crops from above. The tracking from above can provide information on nitrogen levels, vegetation indices, and more.

It is estimated that such tracking is expected to see around $0.4 on each hectare per year. A specific product from Dragonfly is also available for those to take the agricultural data to the next level. The HR-250 from Dragonfly can manage many tasks like yield prediction, harvest monitoring, soil moisture monitoring, seasoned planning, biomass assessment, and more—the data from a CubeSat optical camera is combined with in-house analytics to come up with better analysis and wider coverage.

The CubeSat images supplied in this case will be on ten specific spectral brands so that the resource monitoring can be done at a resolution of 1.4m. One significant advantage of using the product from Dragonfly is that the resolution has been put together in a compact instrument due to the relatively small size of the pixel detector.

In Helping Understand Climate Change

The CubeSat image resolution is among the best in the business. Due to modern cameras’ employment, which can analyze the image and provide a ton of information to machine learning algorithms, it is easy to come out with a map of the Earth in a much more straightforward way. So far, countries have had to rely on single satellites to get their information. Now, the presence of more options will help bring a significantly higher number of data and images. This will help reduce better conclusions, which are far more accurate.

satellite climate monitoring The accuracy levels are incredibly profound while trying to understand climate change. The CubeSat Earth observation looks into the sea ice distribution much better than predecessors thanks to a range of improved statistics like pointing accuracy of fewer than 0.05°, the field of view of 1.5 km, and more. One can use this imagery to understand the sea ice generation, reduction in sea ice, and any abnormalities that may crop up. One of the complex tasks when trying to identify the sea ice is to ensure that the images can distinguish between the various ice blocks.

Currently, some required detection methods can help identify distribution levels at very high accuracy. The satellites with a high-resolution image will obviously have the advantage of placing a smaller sea ice section. Due to the image range’s limitations, countries should decide to open up the appropriate satellite data.

Limitations

There are some limitations to the use of nanosatellites. The less time involved in development coupled with the reduced price for the components means that some constraints are inevitable. The lower radiometric resolution means that these satellites often end up having a narrow spectral range. Furthermore, the spectral resolution is also slightly reduced. As a result, a limitation is created when trying to distinguish between water, ice, snow, and cloud.

The limitations have been slowly disappearing in the last few years. We are at a stage where the use of a CubeSat hyperspectral imager has become indispensable thanks to the numerous advantages compared to the disadvantages.

Conclusion

There are many obvious advantages to using the data provided by CubeSat. One should no longer take up the excuse of budget or quality of data when dealing with these products. It is no wonder that many nations and organizations are starting to realize the advantage of the same, especially in climate change and improving agricultural status. There is expected to be a significant increase in the companies providing free pictures from these products for research and development.
