ISS Science for Everyone

Science Objectives for Everyone
EnduroSat One, the first Bulgarian amateur radio CubeSat mission, popularizes amateur radio activities in Bulgaria. Its goals are to foster participation in space missions by amateur radio enthusiasts in Bulgaria and to provide practice-based satellite communication education in that country for the first time. EnduroSat One is a collaboration with the Space Challenges Program and Bulgarian Amateur Radio.

Experiment Description

Research Overview

  • The EnduroSat One investigation fosters the Amateur Radio’s participation in space research and satellite communication in Bulgaria.
  • The investigation aims to educate the participants in Space Challenges Program and hundreds of students from diverse Bulgarian universities in satellite communication. Universities include but are not limited to Sofia University, Technical University Sofia (Sofia, Bulgaria), and Tech University (Plovdiv, Bulgaria).
  • The investigation intends to increase the popularity of the Bulgarian Federation of Radio Amateurs (BFRA) among young people, therefore, enriching the Radio Amateur community in Bulgaria.

Description

The investigation launches a 1U CubeSat from the International Space Station (ISS). The 1U EnduroSat One CubeSat is a multipurpose platform engineered for space research and applications. The Electrical Power System (EPS+) and the solar panels ensure a power supply during the mission. Two ultra-high frequency (UHF) Transceivers type II and the UHF deployable antenna provide a high-reliable communication system for telemetry, tracking and communications (TT&C) and data. Processing capabilities are ensured by the low power consumption and high-performance computer aboard. A network of sensors and actuators guarantee spacecraft control during the entire mission.
 
The satellite has two beacons. The continuous wave (CW) A1A (the proper radio emission code) beacon transmits its own call sign and telemetry (TLM) data using Morse code. The second is a telemetry beacon that uses Amateur X.25 (AX.25), a data link layer protocol, in datagram-mode. The radio amateurs may listen to the satellite beacon and receive telemetry data from the satellite on a regular basis.
 
Radio amateurs are able to connect to the satellite and receive detailed telemetry information and receive a confirmation from the satellite for every established connection which serves as QSL card, a written confirmation of two-way radio communication.
 
A webpage as part of Space Challenges Educational portal displays all the information and instructions required to connect with the satellite as well as the database for users/participants to upload the data they receive directly from the satellite. A log file with all the successful communications is published. A competition is held in which the call sign with the most uploaded telemetry data is announced by the satellite through the satellite beacon.

Applications

Space Applications
EnduroSat One provides a unique opportunity to test and validate, in orbit, a new type of space education directly linking online space education, hands-on satellite communication education, and real-time space data handling.

Earth Applications
Radio amateurs may listen to the satellite beacon and receive telemetry data from EnduroSat One on a regular basis online. By increasing interest in amateur radio activities and introducing university students throughout Bulgaria to satellite communication, EnduroSat One helps inspire the next generation of space scientists and explorers.

Operations

Operational Requirements and Protocols
NanoRacks CubeSats are delivered to the International Space Station (ISS) already integrated within a NanoRacks CubeSat Deployer (NRCSD) or NanoRacks DoubleWide Deployer (NRDD). A crew member transfers each NRCSD/NRDD from the launch vehicle to the JEM. Visual inspection for damage to each NRCSD is performed. When CubeSat deployment operations begin, the NRCSD/NRDDs are unpacked, mounted on the JAXA Multi-Purpose Experiment Platform (MPEP) and placed on the JEM airlock slide table for transfer outside the ISS. A crew member operates the JEM Remote Manipulating System (JRMS) – to grapple and position for deployment. CubeSats are deployed when JAXA ground controllers command a specific NRCSD.
