Cubehub novel satellite ground stations
connected to crowdsourced
Cubehub network solves the most daunting problems in satellite operations - limited communication time and expensive ground stations.
Cubehub is developing a crowdsourced satellite ground station network, which will consist of clever,
fully integrated, cost-effective and automatic ground stations, to enable worldwide real-time satellite operations.
The first ground station prototype is ready and its QHA antenna concept has been tested by receiving ESTCube-1 and other CubeSats. Currently web interface and ground station signal processing tools are under development. After that it will be possible to build the demonstration network for further development and testing.
Initial ground station will only be able to receive in UHF band but ground stations with transmitting capabilities will follow. Antennas and ground stations for other frequencies like S-band and X-band are already being planned. Some of the software is also open sourced (www.github.com/cubehub).
Ground station network
Satellite operators who would like to use Cubehub network for telecommunication can order service and reserve the network. Clients can use web interface for defining satellite reception parameters, communication periods and locations and data forwarding to mission control systems.
- All ground stations are interconnected to Cubehub network.
- Open market makes crowdsourced network sustainable.
- Part of the revenue will be distributed back to ground station owners.
- Central server coordinates networked ground stations.
Cubehub ground station uses stationary hemispherical quadrifilar helix antenna for reception. Therefore azimuth and elevation tracking is not needed. It is expected to cost about ten times less than than commercial station kits.
- Integrated satellite communication ground station.
- Everything is in one compact enclosure plus antennas.
- Based on software-defined radio (SDR).
- Automatic position calibration.
- Only one Ethernet cable is needed for communication and powering the device.
