Objectives
The objective of this activity is to flight demonstrate a miniaturized technology payload to be carried on a 3-unit CubeSat nano-satellite platform to be deployed from the ISS during the ESA Short Duration Mission in 2015. The payload consists of a reconfigurable software-defined radio (SDR) receiver operating in L-band, and a new 3-axis attitude determination and control subsystem (ADCS) for robust pointing of directional RF antennas. Additionally, the CubeSat platform shall be flight qualified to tailored ESA standards for CubeSats.
Description
The GOMX-3 mission takes advantage of a flight opportunity provided within the ESA ISS Short Duration Mission (SDM) of Danish astronaut, A. Mogensen, during ISS Increment 44. During the SDM, it is planned to deploy a number of Danish CubeSats into orbit for technology demonstration and education purposes.
;
For the GOMX-3 mission, the miniaturized technology payload is supported under Danish national funding and provided as an in-kind contribution.
Given the short timescale for satellite PFM delivery (January 2015 for the ISS flight opportunity), the SDR receiver is based on further developments of a previous unit with flight heritage on the GOMX-1 mission launched in 2013. Improved algorithms for reception of ADS-B signals and GEO telecom spot beam characterization will be tested. The 3-axis ADCS payload contains a processing/interface board and existing sensors/actuators, with the exception of a newly developed IR horizon sensor to provide moderate pointing for RF payloads also during eclipse periods. The platform is a commercial off-the-shelf item with flight heritage from the GOMX-1 mission and can be produced to order on a short timescale.
;
The tasks for this activity include:
;
Phase 1 (2 months):
- Mission design amp; satellite configuration
- Payload accommodation in the platform and interface definition
- Implementation planning, frequency coordination;
;
Phase 2 (6 months until PFM delivery, 3 months operations):
- Final satellite configuration
- Flight software tailoring for the mission
- Platform manufacture, assembly, integration and test
- Payload manufacture and integration in the platform
- Satellite qualification including environmental testing
- Launch campaign amp; ISS safety certification support
- Satellite operations from existing CubeSat ground segment in Denmark;
