The architecture of ETRISat allows for custom solutions to be deployed on a flight-proven platform.
ETRISat will relay signals from ocean buoys collecting oceanographic data such as seawater temperature and wave height.
ETRISat's mission is to perform in-orbit demonstrations of communications technologies as part of ETRI's work on satellite and maritime communication networks.
Alen Space executed the ETRISat project as a turnkey mission, covering all stages including design, assembly, integration, verification, mission control software implementation, and initial in-orbit operations.
Alen Space adapted the ETRISat project to ETRI's requirements and relied on prior mission experience to accelerate the timeline.
The launch of ETRISat will be the fourth flight of the Nuri rocket and will include ETRISat among 12 other satellites.
ETRISat carries a payload based on TREVO, Alen Space's software-defined radio hardware.
ETRISat will verify the transmission of signals through ocean buoys equipped to collect data such as water temperature and wave height.
ETRISat will run two independent applications on its hardware: one created by ETRI for validating advanced communication solutions, and another implemented by Alén Space for transmitting AIS (Automatic Identification System) signals aimed at managing maritime traffic.
ETRISat was developed entirely in Spain and has been delivered to ETRI, where it is awaiting launch aboard a Nuri (KSLV-II) rocket from the Korea Aerospace Research Institute (KARI).
The launch of ETRISat is scheduled to take place in the coming days from the Naro Space Center in South Jeolla Province.
During the mission, signals will be transmitted to ETRISat and subsequently to ground stations to test their effectiveness in real-time monitoring of climatic phenomena and sea conditions.
ETRISat integrates a payload based on Trevo, a high-performance software-defined radio (SDR) from Alén Space.
Alén Space has completed the manufacturing of the ETRISat satellite, a 6U CubeSat developed for the Electronics and Telecommunications Research Institute (ETRI) in South Korea.
The primary objective of ETRISat is to demonstrate communication technologies in orbit, in line with ETRI's initiatives focused on the evolution of satellite and maritime networks.
The fourth launch of the Nuri (KSLV-II) rocket, which will carry ETRISat along with 12 other satellites, will be the first since the establishment of the Korea Aerospace Administration (KASA) in 2024.
Alén Space has executed ETRISat as a turnkey project, covering mission design phases and AIV to testing campaigns, implementation of mission control software (MCS), and initial operations in orbit (LEOP).
