TRISAT-R (TRISAT 2)

Investigate and map ionizing radiation in MEO orbits using several different instruments.

Investigate and map ionizing radiation in MEO orbits using several different instruments for scientific purposes and to demonstrate and test AI algorithms using high performance COTS components and error mitigation techniques in higher radiation environment. The project is supported and coordinated with ESA and the Slovenian Ministry of Economy.

From educational outreach, TRISAT-R satellite mission will promote the use of software defined radio, where a number of outreach activities are being planned that will involve schools, radio amateur societies and media during the first mission of a nanosatellite reaching the MEO orbits. During normal operating conditions the spacecraft will constantly gather measurements of ionizing radiation from the on-board instruments and store them in on- board memory including their mapping information based on information from GNSS receiver.

We are very pleased to announce that the SkyLabs on-board computer with an embedded GNSS receiver provided for the TRISAT-R mission has successfully locked to the navigation signals at the planned altitude of approximately 6000 km in the Medium Earth orbit (MEO).

The nanosatellite TRISAT-R flying in MEO received its first in-orbit software update of the attitude determination and control algorithm to stabilize the spacecraft into a stable two-axis attitude control.

TRISAT-R continues to operate reliably, despite being exposed to intense radiation in mid-Earth orbit (MEO) for more than seven months.
