All about Starlink (Satellite Constellation)



In this post I will tell you about Starlink. It is a sattelite constellation project which is in development by company SpaceX. There aim was to develop low cost and high performance sattelite bus. The expense on this project is nearly 10 Billion US dollar. SpaceX launched their first 60 satellites of constellation in May 2019 into 450 km orbit. They expect to launch 720 sattelites upto coming year 2020. They are trying to make broadband internet connectivity to determine area of the planet. They will be utilizing up to 10000 GHz frequency.

Starlink sattelite use Hall - Effect Thrusters with krypton gas as the reaction mass. It helps in orbit raising and altitude controls. The 60 starlink v0. 9 satellites those are launched in may 201 have following characteristics.
1. It have single solar array and flat panel design with multiple high through put antennas.
2. Mass - 226 kg.
3. It has star tracking navigation system and automatically collide avoidance.
4. Operational altitude of 550 km.

The first 60 starlink satellites are fixed on their orbit. SpaceX are doing their best to make fully this project.

SCADA Network

So welcome to my blog. In this post I am gonna write about SCADA network. This actually come to my mind because of web show named Mr. Robot. The show is awesome if you love hacking believe me you will enjoy the series. So basically the SCADA ( Supervisory Control and Data Acquisition ) is a control system architecture comprising computers, networked data communications and graphical user interface for high level process supervisory management, while also comprising other peripheral devices like programmable logic controllers and discrete proportional-integral-derivative controllers to interface with process plant or machinery. SCADA networks used for monitoring and controlling the  industry like  telecommunication, water plant, etc. It is one of the most commonly used industrial control system, in spite of concerns about SCADA system being vulnerable to cyberattack.  This network is used for gathering info about the system, transferring that info to central site, alerting...

NVIDIA Tesla V100 - First Tensor Core GPU

  8x NVIDIA Tesla V100 32GB Server As we all know NVIDIA processor are so famous now a days. It give a perfect gaming performance and people used it worldwide. The thing is that it is not only use in personal computer but also at data center, where so many super computer are present for providing services. So, NVIDIA Tesla V100 is a first tensor core GPU. It is especially built to focus on AI, High Performance Computing ( HPC ) and graphics. It is powered by NVIDIA Volta Architecture. It comes with configuration 16 and 32GB and have a performance up to 100 CPUs in single GPU. A single server node with V100 GPUs can replace 60 CPUs nodes. DATA CENTER GPUs Image © NVIDIA NVIDIA V100 for NVLINK  Performance with NVIDIA GPU Boost for double precision is  7.8 teraflops and single precision is 15.7 teraflops. Deep learning performance boost is 125 teraflops. Interconnect bandwidth with bidirectional is 300 GB/s. It have memory capacity of 32/16 GB HBM2 with bandwidth 900GB/s. I...

What is Exoplanetology?

Hello, In this post I have talk about Exoplanetology which is a part of Astrology. Exoplanetology is the study of  planet beyond our solar system. Perhaps the greatest challenge for exoplanetology is simply finding such planets. Planets are so small and dim compared to their parent stars, that spotting them against the backdrop of the star is extremely difficult. Confirmed discoveries of exoplanets have only been made since 1988, though the Italian philosopher Giordano Bruno proposed their existence in the sixteenth century. Observatories on Earth and in space have since found thousands of candidates for planets around other stars and new discoveries are being made on a daily basis. Scientists working in this field use an interdisciplinary approach to their research: astronomy and astrophysics are particularly important for detection and observation; astrogeology and astrobiology. Exoplanetology is a young science and there are plenty of Things We Don’t Know.  Learn...
