PROITERES Satellite: Objectives and Technical Specifications
The PROITERES satellite project represents a sophisticated effort to merge consumer-grade technology with space exploration. By utilizing accessible components, the project aims to conduct a series of scientific experiments and communication tests that bridge the gap between professional aerospace engineering and amateur radio operations.
Key Facts
- Primary Frequency: Operates on the 430 MHz amateur radio band.
- Imaging Focus: High-resolution monitoring of the Yodogawa basin and Kansai District.
- Hardware Approach: Utilizes off-the-shelf consumer-grade components for communication tests.
- Optical System: Equipped with a five-lens CMOS camera system.
Project Goals and Objectives
The manufacturer has outlined several secondary goals for PROITERES, focusing on the practical application of radio frequency (RF) propagation and global connectivity.
Radio Propagation and Communication
One of the core objectives is to conduct experiments on two-way radio signal propagation characteristics. By using the 430 MHz amateur radio band, the project seeks to analyze how signals travel between the satellite and ground stations. Additionally, the mission serves as a testbed for satellite communication technology, proving that reliable connectivity can be achieved using standard consumer-grade components.

Global Tracking and Earth Observation
PROITERES is designed to facilitate tracking and communication for amateur radio users worldwide, fostering a global community of operators. Beyond communication, the satellite serves as an orbital observer. It is tasked with monitoring the Yodogawa basin near Osaka and various other regions within the Kansai District using high-resolution imagery.
Technical Specifications
To maintain its position and capture clear images, PROITERES is equipped with a suite of precision sensors and actuators.
Attitude Control and Sensing
The satellite manages its orientation—known as attitude control—through the use of magnetic torquers (electromagnets used to create torque by interacting with Earth's magnetic field) and gyro-sensors. To further refine its positioning, the craft utilizes a solar sensor and a magnetic sensor located on the boom.
Imaging System
The visual monitoring capabilities are powered by a Complementary Metal Oxide Semiconductor (CMOS) camera. This visible spectrum camera features a sophisticated five-lens system with a focal length of 85.3 mm and an f-number of 3.6, allowing for detailed observation of the Japanese landscape.
