GOMX-5 Spacecraft

Demonstrate new operational concepts s high delta-V orbit raising to higher LEO.

Demo of Maritime Situational Awareness payload, and flight qualification of new GOMSpace platform product and the provision of a flight software testbed (on-orbit software lab).

The GOMX-5 platform is further improved for increased power handling, payload volume and reliability over longer mission durations

Demonstrate new operational concepts s high delta-V orbit raising to higher LEO. High speed ISL, high ∆V propulsion. 120 W. >500 m/s (electric). >100000 kbps (X-band). 0.2 deg (3-axis).

The satellite will be equipped with several advanced payloads, which are announced to be:

• TICRA (DK) for X-Band high gain reflectarray antenna, coupled with an X-band transmitter from GomSpace.
• ThrustMe (FR) for Electrical Propulsion.
• EICAS (IT) with miniaturised and improved star tracker.
• Syrlinks (FR) with advanced GNSS Precise Pointing Positioning receiver.
• Deimos (PT) and University of Padova (IT) with high accuracy GNSS receiver.
• Cobham Gaisler (SE), GMV (PL), LIRMM (FR) and UFSC (BR) with powerful radiation tolerant Advanced Payload Processors (APPs) including a GNSS Software receiver.
• Tartu Observatory (EE) with a lightweight Earth observation imager with a radiometric calibration module.
• AIKO (IT) bringing state of the art automation AI into the spacecraft.
• Czech Technical University, Institute of Experimental and Applied Physics (CZ) with state-of-the-art radiation monitor.

Conflicting information about whether there are two CubeSats or one. Latest information implies one 12U CubeSat. ESA infographic from 2024 December shows it as 8U CubeSat now.

• PLATFORM - GomSpace
• ANTENNA - TICRA Reflectarray
• THRUSTER - ThrustMe NPT30i
