ISS Science for Everyone

Science Objectives for Everyone
The NanoRacks-GOMX-3 investigation tests a small satellite with an advanced antenna-pointing system and a variety of communications capabilities. The satellite contains three radios, one of which receives beacons from commercial aircraft to improve air traffic monitoring. Two radios test reception and data downlink in the L-band, used by GPS satellites, and the X-band, used by the military and for weather monitoring, air traffic control and other uses.

Experiment Description

Research Overview

  • The primary mission of NanoRacks-GOMX-3 is to test a number of new or improved payloads in space.
  • NanoRacks-GOMX-3 tests a software-defined radio (receiver), which is tuned to receive L-band signals.
  • NanoRacks-GOMX-3 tests an automatic dependent surveillance-broadcast (ADS-B) receiver that receives ADS-B signals from airplanes.
  • NanoRacks-GOMX-3 also examines an improved Attitude Determination and Control System (ADCS) that verifies among others reaction wheels, Fine Sun Sensors, and thermopiles.
  • An X-band transmitter that tests the possibility to send 3 Mbps from a CubeSat is also part of the NanoRacks-GOMX-3 investigation.


The objective of the NanoRacks-GOMX-3 mission is to flight demonstrate a miniaturized technology payload to be carried on a 3-unit CubeSat nano-satellite platform to be deployed from the International Space Station (ISS) during the European Space Agency (ESA) Short Duration Mission in 2015.
The investigation consists of: a reconfigurable software-defined radio receiver operating in the L-band, a new 3-axis attitude determination and control subsystem for robust pointing of directional radio frequency (RF) antennas, an improved version of an automatic dependent surveillance-broadcast (ADS-B) receiver and antenna for recording ADS-B signals from airplanes, an X-band transmitter and X-Band patch antenna to be tested.
Additionally, the CubeSat platform is flight qualified to tailored ESA standards for CubeSats. The mission leads to the maturation of the technology payloads, reconfigurable software-defined radio (SDR) and 3-axis Attitude Determination and Control System (ADCS), to high Technology Readiness Levels such that they may be used in future missions with a lower technical risk.

Space Applications
The NanoRacks-GOMX-3 investigation tests new payloads in space, including radio receivers and an advanced pointing system. It contains an advanced pointing system to control directional antennas, improving the ability to receive radio signals from Earth or from other satellites. Gomspace, a Danish company, designed the satellite, including its pointing system and radio payloads. A Danish astronaut is scheduled to be on board the International Space Station during deployment, sparking renewed interest in space exploration among the Danish public.

Earth Applications
The NanoRacks-GOMX-3 satellite receives automatic dependent surveillance-broadcast (ADS-B) signals from airplanes flying above Earth, improving international air traffic monitoring and safety in areas where no ground stations are nearby. The investigation also tests a new miniaturized three-axis satellite control system that can be used to more accurately aim payloads on future satellites, benefiting users on Earth.

Operational Requirements and Protocols


NanoRacks CubeSats are delivered to the ISS already integrated within a NanoRacks CubeSat Deployer (NRCSD). A crew member transfers each NRCSD from the launch vehicle to the JEM. Visual inspection for damage to each NRCSD is performed. When CubeSat deployment operations begin, the NRCSDs 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.
