Project Mapinduzi Satellite
Making the space probe for earth observation and environmental monitoring
As I continue to work tirelessly on this project (Mapinduzi-Sat), I am pleased with the progress so far as I have successful integrated the subsystems for this beautiful space probe.
The prototype is designed for earth observation and environmental monitoring. After countless hours, weeks and months, finally the probe has shown a positive response from its onboard computer, camera and its response weather sensors. With the computing power of BCM2837 chipset, the quard-core ARM COrtex-A53 processor at clock speed of 1.2GHz and 1GB of RAM, the features are more than enough to support the sensors and capture devices aboard for space exploration.
In 1969, the Apollo mission guidance computer(AGC) had only 2.048MHz clock speed and 2KB of RAM which is 600 times lesser processing speed to what Mapinduzi have, but despite its limited memory and processing power compare to most of todays missions, it was able to perform complex calculations and navigate the spacecraft to the moon and back, so in this case there is no room for excuse for
Mapinduzi project (of course, there a lot other parameters to consider).
Technically, the mission for this product is to do a number of things, one is to perfom earth observation by utilizing the installed camera which is capable of collecting images of earth atmosphere, oceans and land surface.
Secondly, to measure temperature, humidity and air pressure in the atmosphere and also to check the percentage of greenhouse gases at that particular region.
This information are sent back to the ground station on real time bases via onboard radio subsystem. The power subsystem incorporated the lithium-ion battery together with solar panels.
Due to the fact that the cost of building and launching pocketcube/cubesat and other small satellites being so high and expensive, making the project take ages to achieve.
Instead, I have decided to challenge myself by connecting the technology to a weather balloon and testing its capabilities (well, I will need to forget low earth orbit for now).Let the project inspire the next generation of STEM enthusiasts and explorers.
By showcasing the capabilities and possibilities of space technology, I am sure this is among the major ways to encourage young people to pursue careers in STEM fields and continue to push boundaries
