rakenneosat

Rakenneosat is a fictional satellite system created for illustrative purposes in this article. It describes a family of small satellites intended for Earth observation and communications in low Earth orbit.

System concept: The Rakenneosat constellation consists of a large number of small, modular satellites in a

Mission capabilities: The fictional system targets applications such as disaster response, maritime surveillance, agriculture monitoring, and

Development and status: Rakenneosat exists as a concept rather than an operational program. Proposals describe phased

Impact and context: As a hypothetical architecture, Rakenneosat serves to illustrate common considerations in small-satellite constellations,
