• Template of kicad for the subsystem:

• 1st pic is the SSCB, Subsystem carrier board, used to connect all the subsystems. Box 32 unlabeled

• DTUSat2 was 2014, DTUSAT3 last development 1 year ago

• OBC, there is not software, it is just a Linux computer.

• There is no software at all in any subsystem.

• The ones deciding the sat is denis and rene, I can send a email to him. Denis implemented the design.

• OBC: It is know that works, but with a problem when you turns on. I would need to ask Denis how to use before conecting it.

• COM: It is working with the SSCB but no integration. There is a report on findit (validation of transmitter) [in denish]. There are 4 pcbs, 2 for s band and 2 for lora. In my project I am only going to use Lora, but I need to ask denis how to connect to the lora module first.

• EPS: Burns when there is not load. You can expect some voltages and batteries. It is a complex design in which there is EPS in each solar panel. For this mission we are not going to use the solar panels, only the regulators.

The most recent versions of the PCB’s are in the black boxes, near the weirdbox of DTUSAT1.

I should take the thesis from DTU library, in findit. DTUSAT3.

DTUSat 3 Wishes for Housekeeping:

• Air temperature
• Air pressure
• Batt voltage
• HW System status (ON/OFF)
• Particle counter status

Things to buy:

• Can bus example components.

Next questions:

• What are the interfaces in each subsystem.
• I need to meet with Denis as soon as possible.

Rene gave me access to the DTU inside:

• SYSENG: DTUSAT and DTUSAT2 not interesing folders. DTUSAT3 subsystem EPS there are some reports. Description of the idea of the EPS, not very detailed. More detailed description here, the original design of DTUSAT3 EPS.
