UNISAT-5 mission

Characteristics

UNISAT-5 is the first satellite designed, built and launched by GAUSS Srl, the private Company that inherits the experience gained with the UniSat program at the School of Aerospace Engineering of the University of Rome “Sapienza.

The project was developed in collaboration with students and researchers of the Space Science Center of MSU (Morehead State University, KY, USA).

UniSat-5 is an educational civilian microsatellite, with a cuboid aluminum structure whose panels have a surface area of 50 x 50 x 50 cm. The total microsatellite mass weights 35 kg.

The launch of UniSat-5 satellite, boarded on the DNEPR rocket – the orbital launcher managed by the company Kosmotras – took place on 21 November 2013 from Dombarovsky Cosmodrome in Yasny (Orenburg region, Russia), marking an historical event in the world of CubeSats and PocketQubes. In fact, the microsatellite UniSat-5 boarded and then deployed four CubeSats and four PocketQubes for the first time ever. 

UniSat-5 small spacecraft is a technology demonstrator and also an innovative launch platform built to comply with the CubeSat and PocketQube standards, this way also expanding access to ASpace services with the advantage of reducing the customers’ costs related to the administrative preparation and the launch itself.

The spacecraft was inserted into a near-SSO orbit with an altitude of 634 km at 07:25:48 UTC.

UNISAT-5 Payloads

Deployable Payload 

UniSat-5 carried four CubeSats:

and four PocketQubes:

  • Eagle1 (USA)
  • Eagle2 (USA)
  • QBScout (USA)                                                                                                                                                                                                
  • WREN (Germany)                                                                                                                                                                                                                                   

These CubeSats and PocketQubes have all (except one, Dove-4) been released into orbit from the UniSat-5 satellite, launched by the Dnepr rocket.

Fixed Payload

UniSat-5 carried two IOV/IOD payloads (technological experiments to perform tests on equipment in space environment):

  • ALICE-2 (Italy)
  • Photovoltaic panel (Italy)

Mission objectives

  • Launch of CubeSats using PEPPOD – PUCPSAT,  I-CUBE 1,– HUMSAT-D, – Dove-4
  • Launch of PocketQubes using MRFOD (with Morehead State University): – T-LogoQube, 50$Sat (Eagle-1 and Eagle-2) – QBScout, – WREN
  • IOD/IOV Technological Tests (CoverGlass, OBDH, ADCS)
 

Results

  • PEPPOD and MRFOD systems correctly released 4 PocketQubes and 3 CubeSats.
  • PocketQubes have been successfully launched in Space for the first time
  • 6 out of 7 satellites have been received
  • DOVE-4 was not deployed (safety procedure was not applied after customer request)
The following facts reveal the significance of this event:
  • First launch of CubeSats and PocketQubes from another nanosatellite
  • First launch of PocketQubes ever
  • First Peruvian satellites, PUCP-Sat-1 and PocketPUCP-Sat (that will be released from PUCP-Sat-1)
  • First test of Pulsed Plasma Thruster on a picosatellite (WREN by Sta.do.Ko)

In the last week of integration, the CubeSats and PocketQubes were integrated on board the UNISAT-5, inside the PEPPOD (GAUSS CubeSat deployer system) and MRFOD (designed by Morehead State University, USA, in collaboration with GAUSS Srl) deployers.

  • CubeSats 

PUCP-Sat-1PUCP-Sat-1

Country: Perù

Developer: Pontificia Universidad Catolica del Perù

Project Manager: Prof. Jorge Heraud

1U Cubesat

PUCP-Sat 1 is the first Peruvian satellite built by the Institute for Radio Astronomy of the Pontificia Universidad Católica del Perú (INRAS-PUCP).

The 1270 g satellite is built on the 1U-CubeSat form factor. It was configurated to transmit temperature readings from 19 internal sensors and to deploy the 97 g Pocket-PUCP femtosatellite.
