Here we present the development and qualification of the highly integrated satellite avionics stack of ESTCube-2, a three-unit CubeSat carrying various in-orbit demonstration payloads. The primary payload is the Plasma Brake (PB), which is novel deorbiting technology for low Earth orbit (LEO) satellites. The Earth observation payload (EOP) consists of two cameras imaging the planet in 660 nm and 8...Show More
During the course of a space mission unexpected events can occur regardless of rigorous testing. In order to ensure the ability of a spacecraft to recover and adapt to new situations, it may be necessary to update the firmware for resolving the software issues, work around hardware problems, or introduce new features. The importance of remote firmware updates as well as a method to calculate an in...Show More
In this article, we report on the in-orbit experience - an overview of ESTCube-1 operations from the launch until the experiment, as well as on lessons learned from five years of development and almost two years of operations. Lessons are identified from the point of view of system engineering, electrical engineering, mechanical engineering, software engineering, testing and measurements, payload,...Show More
