How are Small Satellites Changing The World of Earth Observation

Small satellites have revolutionized the world of earth observation. Consistent innovation has led to advancement in technology and miniaturization of satellites.

It has led to an increased scope of services or data that satellites can provide for research, study, and growth. The field of earth observation has seen some of the most promising advancements with the introduction of small satellites.

Definition

Small satellites have broadly been defined as any satellites weighing below 1,000 kgs. These satellites, robustly being used in earth observation, have improved the face of GIS and technology over time.

They can further be defined based on their weight. 

Minisatellites- Satellites weighing between 100-500kgs 
Microsatellites- Satellites weighing between 10-100kgs
Nanosatellites-Satellites weighing between 1-10kgs 
Picosatellites-Satellites that weight below 1kg 

Small or nanosatellites are rapidly changing earth observation by providing data and information that is accurate and up to date. This has immensely helped in decision making and has improved turnaround time on sensitive researches and studies.

These satellites are usually launched as a swarm and not singularly as each of them might specialize in a particular kind of data capturing. A connected system of satellites provides accurate data that is usually compiled by a bigger satellite (Usually called the Mother Satellite).

Benefits

One of the key advantages of these small satellites is their production costs. These satellites have minimized implicit costs due to size reduction.

The implementation of plans and strategies is also made more efficient since people are required per project. The unit costs are reduced considerably.

Due to lower expenditure and easy implementation, the adherence to the project’s proposed plan is higher as there are fewer chances of drastic mishaps due to the size and weight of satellites.

Value for money

Small satellites are used in a variety of industries such as telecom, healthcare, disaster management, environment protection, and infrastructure development.

Small satellites can help enhance the space programs for developing countries due to their low costs and efficiency.

The fact that they are closely integrated with modern tech is also a bonus. These satellites work seamlessly with powerful modern day computers and connect well with collateral technology that may be needed for support functions.

Although traditional satellites can perform certain complex functions that smaller satellites do not have the potential to perform. These powerful machines still boast a whole range of specialized tasks that can be collectively utilized at a larger scale while saving costs.

Small satellites are beautiful, sophisticated technology that shows a healthy future. All in all, it is a force to be reckoned with.
