Satellite cameras are becoming more sophisticated with each passing day. These mini cameras have become very important, whether it is for simple Earth observation or more advanced research. The remote sensing technologies used today are just terrific; with the help of these satellite images, you now have access to cutting-edge information about the Earth’s surface. Such systems provide countless opportunities.
Capturing and analyzing the images will help you watch, plan and prepare/predict the outcome of anything on Earth. The camera will allow you to get hyperspectral, multispectral, and panchromatic images.
CubeSat nanosatellites are considered the future of progressive technologies today for Earth observation. These satellites are pretty small and very versatile. Apart from Earth observation, these nanosatellites can also be used for various purposes like climate monitoring, communications, disaster response, etc.
In this article, we will discuss how CubeSat cameras can become the future of Earth observation.
What Is Earth Observation?
As you can guess by the name, Earth observation is the process of gathering information about the Earth’s biological, chemical, and physical systems. The process entails assessing and monitoring the status of natural and artificial environments and the resultant changes.
In the past few years, Earth observation has become very sophisticated, thanks to the development of various types of remote-sensing satellites. In today’s time, some of the many instruments used include floating buoys for monitoring the salinity, temperature, and currents of the ocean. They also include land stations for recording rainwater trends and air quality, radars and sonars for estimating birds and fish populations, GPS and seismic stations, etc.
Earth observation has become very important because of the impact that everyday human activities have on the environment.
Why Is Earth Observation Important?
We live on a planet that has a fragile ecosystem and limited resources. The climate and the Earth’s environment are determined by the complex relationship between different elements like the land, glaciers, the oceans, and the atmosphere; additionally, you also have to consider the ever-increasing ability of humanity to impact them.
With the help of Earth observation data, we will have thorough knowledge about our planet. This way, we will be able to concentrate on optimizing and managing our resources and understand our ecosystem’s various other complexities.
What Is A CubeSat?
Before learning what a CubeSat camera is, let’s first look into CubeSats. CubeSats are a special type of satellite that does not measure more than 10cm². Its maximum weight is 3lbs, making it perfect for launching with a rocket carrying a heavier payload.
While these satellites were initially developed for educational purposes, they are currently being used for revolving the low Earth orbit and specific functions like commercial-oriented missions, scientific research, and tech demonstrations.
What Is The Camera System For CubeSats?
In the past 20 years, CubeSats have become a pretty known name in the space industry. Apart from their pocket-friendly designs, launching these satellites is also very easy. In this section, we will learn more about how the CubeSat camera works and various other development processes.
One of the most critical components of CubeSat satellites is the camera. These imagery devices are sold separately and available in a wide range of spectral and resolution imaging capabilities. These cameras come in different sizes and functions, and you can choose one based on your project requirements.
All CubeSat cameras are capable of using a wide bandwidth. Due to the low resolution, various processes get simplified, like gradient sensing, storage, revisiting time, etc. Since these cameras have a modular design and CubeSat technology, you can be sure that you will get very precise images.
Since the satellites are used for a wide range of projects, you can find highly customizable cameras easily integrated into the satellite design.
Selecting The Right CubeSat Satellite For The Mission
Like other space cameras, CubeSat cameras are specifically designed to reflect the signal from a space object and store it as a hyper-spectral, multichromatic, and panchromatic image.
When it comes to selecting the right CubeSat camera, you need to consider some basic factors like:
- Size: The satellites that will be carrying the CubeSat camera modules should match the model of the camera.
- Flexibility: The camera used should capture a wide range of data to ensure maximum convenience. Additionally, they should also be capable of being integrated into all satellite designs.
- Technical Aspects: These aspects range from the in-built data storage to the operating temperature range. The satellites should be capable of meeting your imaging and orbiting needs. They should also provide storage space anywhere between 128 and 1024 GB. Most cameras also function optimally between -20° and +70°C.
CubeSats have been working hard to expand its holding in the space exploration sector for the last few years. These small-sized satellites can pack almost any extra accessory, like a camera or computer, thanks to the simplistic design.
A CubeSat camera is considered one of the most critical components; you must choose the right camera because it will determine the quality of the image and the success of the mission. With the right CubeSat camera, you will be able to capture the images you are looking for.
