SKAIDOCK
Primary purpose
SKAIDOCK serves as a carrier board designed for the Xiphos Q8(S) modules equipped with the Xilinx Zynq UltraScale+ Multi-Processor System-on-Chip (MPSoC). Its primary purpose is to facilitate seamless integration into satellite systems, boasting a mechanical PC104 form factor and offering configurable interfaces accessible through the side connectors of the carrier board. The board has a matching connector to Simera Sense Cubesat imagers.

Technical specification
SKAIDOCK does not require any additional software or hardware on top of Xiphos delivered SDK and user manual. The board serves purely as an interface board without breaking any compatibility with existing Xiphos or Xilinx tools. Pinnout and schematic are provided to configure interfaces correctly.
CAMERA CONNECTOR
Camera connector is configured with one-to-one matching interfaces and pinout as a Simera Sense Cubesat imager. It contains I2C, SPI, PPS, LVDS pairs compatible with Simera protocol as well as LVDS pairs for SpaceWire signals, and 5V power output to the camera.
CAN
SKAIDOCK features two CAN interfaces, connected to the PS side of the MPSoC. Bus termination can be enabled in the connector, by connecting specified pins.
I2C
I2C operates at 3V3. The interface is taken out to the Camera connector and to the separate I2C connector. Only one connector can be used.
SPI
SPI interface also operates at 3V3 and has also two different connectors. SPI in the Camera connector has one chip select pin, standalone SPI has three chip select pins. Only one connector can be used.
RSXXX
RSxxx interface is dependent on Q8 configuration (1x RS422 or 1x RS485 or 2x RS232).
Qualification
SKAIDOCK is qualified to operate in a space environment. During thermal-vacuum (TVAC) testing, it was tested for operational temperatures between -40°C and +60°C. The board has also undergone sine and random vibration testing, shock testing, and radiated emissions measurements. The qualification testing campaign was co-financed by the European Union in the project “Kvalifikačné testovanie elektroniky SKAIDOCK”.
„We're moving towards satellite autonomy which is affordable for all spacecrafts. That's the future, that's where we're heading.“
