35+
The Joint Global Multi-Nations Birds Satellite project, or BIRDS project for short, was established by the Kyushu Institute of Technology ([Kyutech](https://www.kyutech.ac.jp/english/)) to help countries build their first satellite. Young engineers from select countries get to learn about space engineering at Kyutech, mostly using the 1U CubeSat.
36+
37+
The BIRDS project has two main objectives:
38+
39+
1. Experience the entire cycle of a satellite project, from mission definition to operation, in a hands-on manner.
40+
2. Have a strategy for sustainability after the training.
41+
42+
The primary goal is not to build a satellite, but to establish a sustainable space program in each member country.
43+
44+
So far, there have been 4 completed and one ongoing BIRDS missions, which are:
45+
1. BIRDS-1: Bangladesh, Japan, Mongolia, Ghana and Nigeria .
46+
2. BIRDS-2: Bhutan, Philippines and Malaysia.
47+
3. BIRDS-3: Japan, Sri Lanka and Nepal.
48+
4. BIRDS-4: Japan, Philippines and Paraguay.
49+
5. BIRDS-5: Japan, Uganda and Zimbabwe.
50+
51+
52+
Kyutech's fellowship programs (PNST) and Space Engineering International Course (SEIC) provide hands-on space engineering training using CubeSat development, enabling each mission to be completed in two years. The goal of open sourcing the process is to enable teams from across the world to develop their own countries' first satellites.

# The BIRDS Bus
74+
75+
The BIRDS (Birds Satellite) Bus is a comprehensive hardware platform designed to meet the needs of CubeSat missions. It provides a standardized framework for integrating key subsystems, enabling teams to focus on mission-specific payloads and objectives. The BIRDS Bus consists of several interconnected boards, each responsible for specific functions such as power management, communication, and data handling. This modular approach simplifies development and ensures reliability for CubeSat missions.
76+

90+
91+
### [On-Board Computer (OBC)]({{site.url}}/overview/birds/obc-page.html)
92+
The OBC is the brain of the satellite, handling core computing tasks such as command execution, data management, and subsystem coordination. It uses a PIC microcontroller for reliable and efficient operation.
93+
94+
### [Electrical Power System (EPS)]({{site.url}}/overview/birds/fab-page.html)
95+
The EPS manages power generation, storage, and distribution. It ensures that all subsystems receive adequate power and that the battery is charged efficiently. The main board that drives this is the FAB on a 1U and 2U configuration and the EPS board on a 3U+ confuguration. the [Rear Access Board (RAB)]({{site.url}}/overview/birds/rab-page.html) and the [Solar Panel board]({{site.url}}/overview/birds/solar-page.html) are also a part of this system in the BIRDS Bus.
96+
97+
### Attitude Determination and Control System (ADCS)
98+
The ADCS controls the satellite's orientation and stability, ensuring that it maintains the correct position for mission operations.
99+
100+
### [Communications (COM)]({{site.url}}/overview/birds/com-page.html)
101+
The COM subsystem oversees data transmission to and from the satellite. It uses UHF/VHF communication for reliable telemetry and command handling. The [antenna board]({{site.url}}/overview/birds/antenna-page.html) carries the COM, APRS and GPS antennas as well as their release mechanism.

## Systems Engineering Approach
10+
Building a satellite involves complex systems that need careful planning and integration. Here are some key concepts of systems engineering that will guide your CubeSat development:
11+
12+
### 1. **Understanding Systems Engineering**
13+
- Systems engineering is the interdisciplinary approach to designing and managing complex systems.
14+
- It focuses on understanding the entire system, from design and development to testing and operation, ensuring that all parts work together to meet the mission goals.
15+
16+
### 2. **Defining Requirements**
17+
- Start by defining your satellite’s mission and operational goals.
18+
- Understand the system's constraints, such as size, weight, power, and budget, and define technical requirements to meet them.
19+
20+
### 3. **Subsystems Integration**
21+
- Satellites consist of multiple subsystems such as power, communication, and attitude control. Systems engineering ensures that all subsystems integrate seamlessly.
22+
- Learn how these subsystems interact and contribute to the overall mission’s success.
23+
24+
### 4. **Risk Management**
25+
- Identify potential risks early in the development process and implement strategies to mitigate them.
26+
- Regular testing, reviews, and simulations help identify weak points and prevent system failures.
27+
28+

29+
30+
## What are the phases of a satellite?
31+
The development and deployment of a satellite involve a series of carefully structured phases to ensure the mission's success. From initial concept discussions to final pre-launch verifications, these phases guide teams through designing, building, and testing the satellite to meet stringent space industry standards.
32+
33+
Each phase acts as a checkpoint to confirm that requirements are met and potential risks are mitigated. Understanding the phases - including the
34+

35+
- [Preliminary Design Review (PDR)],
36+
- [Critical Design Review (CDR)], and

- [Flight Readiness Review (FRR)]

73+
74+
These phases create a structured pathway from conceptualization to launch, with each review and testing stage serving as a critical checkpoint. The **MDR** sets the scope, the **PDR** checks the initial design feasibility, the **CDR** finalizes the detailed design, and **FRR** ensures that the satellite is robust and mission-ready. This structured approach helps in mitigating risks, ensuring quality, and promoting mission success.
75+
76+
With this foundational knowledge, you’ll be better equipped to dive into the satellite-building process. The next step is to select the path that best fits your experience level and start building!
