Radiation Radiation is a general denomination of all the high-energy particles and electromagnetic waves that exist in outer space, outside of Earth most inner layers of protective atmosphere and magnetic field. This radiation comes from multiple sources yet e...

Index Domain Description M-0010 General The satellite will be launched in a LEO orbit corresponding to both its purpose and the international regulations. M-0020 General The satellite must not contain entry resistant materials or completely detachable...

Owner Req ID Requirement Text Requirement Note OBC OBC-0010 The OBC shall monitor all spacecraft subsystems.   OBC OBC-0020 The OBC shall have an Scheduler which determines the execution of different tasks through time.   OBC OBC-0030 The OBC shall pr...

Document scope In satellite systems, the ADCS is essential to maintain the proper orientation and stability of the spacecraft. This section will initially present the ADCS of the project, presenting some inicial concepts needed for understanding the theory and...

Introduction The hardware of the Attitude Determination and Control System (ADCS) is essential for the satellite’s operation. Without it, the satellite would be unable to gather critical data about its orientation and environment in space, which is necessary f...

Document scope This document aims to give insight into the design choices taken in the development of the P/L 1, a video graphics array camera (VGA) conceived originally to monitor the deforestation of the Indonesian rainforest, but later repurposed to collec...

The software of the Attitude Determination and Control System (ADCS) is equally essential for the satellite’s operation. Without it, the satellite would lack the intelligence to interpret critical data about its orientation and respond to its environment in sp...

The VGA Payload differs from P/L 2 and P/L3 greatly, both in purpose and development. As previously stated the VGA camera itself is a COTS component, meaning no development of the actual instrument is done as a part of the hardware design. Despithe this, in th...

DOCUMENT SCOPE The aim of this document is to explain the subsystem verification tests to carry out on Attitude Determination & Control Subsystem, in order to obtain/discard any anomaly that the subsystem could suffer during the performance of these test. TEST...

Code structure COMMANDS: This part specifies the different commands used to transmit the data between the OBC and the Camera. These commands are specified on the datasheet, and are sent using the “Basic” functions. These commands are declared on the camerav2...

I2C testing in case of failureThere is a problem with the I2C communication that makes the code fail. To solve this problem the next tests has been done:1. Verify the connectionsAll the I2C connections are well connected with the corresponding PINS2. Check the...

Camera testing How to take and extract an image In order to take a photo the PTC06 and a STML4, which will be replaced by the OBC-COMMS board in due time, must be connected appropriately. The camera must be provided with a voltage of at least 3.3V to be in wor...

Functional Architecture The EPS is responsible for managing the energy throughout the satellite, including charging the battery and distributing power to the various subsystems. It is divided into two main blocks: the Energy Harvest Block, which is in charge o...

Design Choices Up next is provided a table including the most important components of the EPS. In the following sections is found information about each one of them as well as the overall design of the system. Quick Facts Table Component Model Solar Ce...

The EPS software is encapsulated within the EPS task. It's main functionality is providing the OBC with battery readings on it's voltage, current generated, capacity, temperature and charging status. The task will also indicate any error generated by the Power...

Document scope This document aims to describe the design process and considerations involved in the designing a L-band Radio Frequency Interference (RFI) payload with the purpose of monitoring and mapping the Electromagnetic Interference (EMI) coming from the ...

The EPS consists of two main blocks. The process begins by soldering the MPPTs, and with the help of a solar simulator, they are tested using a solar cell to ensure proper functionality and that the output is as expected. Next, the Battery Charge Block is sold...

Test Description and Objectives The objective of these tests is to check the correct functioning of the EPS system in all its parts, to ensure correct management of the energy between the solar panels and the battery to ensure the correct management of the sup...
