GUMUSH's n-ART OBCOMMS product is a management and communication unit for use on CubeSats, MicroSats, and other non-standard spacecraft. n-ART OBCOMMS has been designed for CubeSats and NanoSats in order to manage data handling, TLM & TC and to control the other subsystems. n-ART OBCOMMS is a joint subsystem which consists of an On Board Computer (OBC) and a telecommunication system in the same PCB, to reduce required space, mass and power. n-ART OBCOMMS conforms to the PC104 CubeSat form.

n-ART OBCOMMS has different options for Engineering and Flight Models. In addition, n-ART OBCOMMS has several options for communication module usability as beacon or modem.

The first versions of n-ART OBCOMMS are designed and produced by Ertek Space Systems for the QB50 project, for use in CubeSats developed by ITU-USTTL. n-ART OBCOMMS has been qualified in space, achieving heritage through the HAVELSAT (2U), BeEagleSat (2U) and UBAKUSAT (3U) projects.

Some of the key features include:

  • management of satellite software and operation of subsystems and payloads
  • modular design and integrated architecture, allowing for redundancy, multitasking and other capabilities
  • a Real Time Operating System (RTOS), back-up memory units, easy programming
