It is time to say goodbye to NASA's Neil Gehrels Swift Observatory. After nearly 22 years of service, the satellite re-entered Earth's atmosphere on November 4 at 7:39 EST over the North Sumatra region of Indonesia. The featured image is a mosaic created in 2018 using the first one million images captured by the satellite's Ultraviolet/Optical Telescope. Swift had a combination of instruments, including an X-ray telescope and a gamma-ray telescope, that worked together to enable humanity to study, in unprecedented detail, the fastest and most energetic explosions in the universe. The most recent solar maximum accelerated the decay of the satellite's orbit. An innovative mission to rescue Swift by boosting its orbit was not successful. Swift burned on reentry like a shooting star, but the impressive data acquired by the telescope over its mission will continue to bring light to the mysteries of the cosmos for years to come. May it keep inspiring new missions to boldly go into space, explore new data and seek out new science.

In the project, ground station hardware and interface studies were carried out to obtain signals from cube satellites sent to space to perform scientific missions in Low Earth Orbit. In the designed hardware, receiver modules named Lora, which can receive signals at 433, 868, and 915 MHz frequencies, which are among the UHF band frequencies, were preferred. The design is equipped with peripherals to improve the user interface and is supported by innovative methods. On the software side, the hardware was tested on the TinyGS platform, where the signals from the satellites were transferred to the internet environment by the ground stations, and telemetry packages were received from the satellites, both successful and unsuccessful.

In the study, gateway hardware is designed, which receives and processes data from various industrial communication protocols where data flow takes place in industrial environments and transfers this data to the cloud environment over the internet. The design, which was carried out with the technical parameters determined under the conditions of the industrial environments and the purpose of the project, was tested with a basic prototype. As a result of the study, sample CAN Bus data was transferred to the cloud environment. Hardware design has also been improved by evaluating parameters such as power, protocol support, ergonomics, and connection features.

In the study, a hardware design and implementation have been made that allows connection to the CAN Bus network, which is an important part of the in-vehicle communication network infrastructure, and can be connected via the OBD-II port found in the majority of vehicles. With the examination of the general structure of the CAN Bus protocol, technical requirements were created and CAN Bus communication was made by performing software tests with a prototype circuit. The circuit board design of the hardware was made with the determined system requirements. The final design was created by considering power options, interface options, peripherals, and various user parameters.
2025 Eylül ayninda gerçekleştirdiğimiz uçuş sonrasi değerlendirmelerimizi geliştirmek için telemetri verilerini uçuş videosuna senkronize ettim. Python’da OpenCV, PIL, Numpy ve Pandas kullanarak verilerin anlik olarak görüntülenmesini sağladim. Ortaya çikan bu keyifli çalişmayi sizlerle paylaşmaktan mutluluk duyuyorum. 🚀🛰️📡
Merih Space takimimiz 2025 TEKNOFEST Model Uydu Yarişmasinda şampiyonlar listesine 2. olarak adini yazdi! Üniversiteye başladiğimdan bu güne süren bu macerada yillarim geçti. Geldiğimiz bu noktada ilk günden itibaren çok büyük işler başardik. Her ne kadar değerli ekibim süreci ikinci olarak tamamlasa da benim gözümde çizik bile almadan yere inen, neredeyse hatasiz çalişan ve haberleşme ve otonom yetenekler dahil bütün görevleri sağlayan model uydusu ile tüm zamanlarin en iyisi ve şampiyonu olarak kalacak. Bu serüvenin artik sonuna geldik. Sirada çok daha büyük çalişmalara imza atmak için yola koyuluyoruz. Süreç boyunca büyük emekler veren ekibime ve desteklerini esirgemeyen danişmanima teşekkürü borç bilirim.
Sizlere Merih Space ile 2025 yilindaki gökyüzü serüvenimin hikayesinden kisaca bahsetmek isterim. Bununla birlikte gerçekleştirdiğim çalişmalardan bazilarini da sizlere sunuyorum.
