BRAC ONNESHA is a part of the larger Joint Global Multi National BIRD Project. 5 Satellites from 5 country (Japan, Ghana, Mongolia, Nigeria & Bangladesh) will orbit earth and collectively perform 6 Missions.
Mission 1: Capture image of Homeland Country
Natural resource monitoring one of the most used application of satellite technology. The main mission of BIRDS satellites is to capture a picture of respective homeland countries and send it back to respective country’s ground station. BRAC Onnesha has 2 cameras onboard. The primary camera is a 5 MP CMOS camera. We expect it capture 100 km/pixel spatial resolution picture of the earth. The auxiliary 0.3 MP camera serves as a backup camera.
Mission 2: Digi-Singer
BRAC ONNESHA will broadcast our National Anthem from space. This mission aims to motivate the young enthusiastic minds for career in space engineering. Anyone with a UHF receiver can receive and listen to our national anthem, played from space. For more details: http://birds.ele.kyutech.ac.jp/digi.html
Mission 3: SEL Detection
Single Event Latchup or SEL is a phenomenon related to harsh space environment. For Galactic Cosmic Radiation, microprocessors sometimes experiences internal short circuit. This disrupts satellite operation. BIRDS constellation, aims to map SEL events for LEO and provide a statistical database for interested audience.
Mission 4: Atmospheric Drag Measurement
By using data from all 5 of the CubeSats, BIRDS project aims for measuring atmospheric drag more reliably by observing the decay rate of satellites. This data will provide more in depth data for our atmosphere and its effect on CubeSat mission lifetime.
Mission 5: Precise Satellite Position Detection System
In addition to 5 countries building satellites, Taiwan and Thailand are also participating in BIRDS project by sharing their ground station. 7 ground station in total enables us to experiment a reverse GPS system. This way, we can track our satellite without using any GPS.
Mission 6: Ground Station Network
One of the limiting factor for University based CubeSat project is, limited mission life and communication window. A ground station network can effectively increase the communication window. BIRDS project aim to demonstrate such a network operation for CubeSats. Participating countries are, Japan, Ghana, Mongolia, Nigeria, Bangladesh, Taiwan & Thailand.
