What are Low Earth Orbit (LEO) satellites?


A Low Earth Orbit satellite is a geo-stationary satellite that flies at an altitude of 2000km from the earth’s surface. These LEO satellites are used for limited area coverage. When compared to that of the conventional geo-centric satellites, LEO satellites require very less amount of energy for placing the satellite into orbit. This, in turn, results in high bandwidth and low latency for communication.


What is satellite constellation?


A group of artificial satellites that work collectively is called satellite constellation. Usually, satellite constellations are formed with the LEO satellites, which are placed in sets of complementary orbital planes. Satellites of these constellations communicate to the earth by globally distributed radio stations.

What is Project Kuiper?


Kuiper Systems LLC is one of the subsidiaries of Amazon, founded in 2019, with a huge investment of $10 billion. The primary objective of Kuiper Systems is to deploy a constellation of 3,263 LEO satellites for providing internet connectivity to the remote locations that cannot afford optical fiber connectivity. Amazon named this project as Project Kuiper.


The Kuiper Systems LLC and the Project Kuiper were named after the astronomical term Kuiper belt. Kuiper belt is defined as the circumstellar disc in outer solar system extending from the orbit of Neptune up to 50 AU (Astronomical Units) from the Sun.

The approval for such astronomical communication projects is handled by Federal Communications Commission (FCC). Though Amazon has announced Project Kuiper in last spring, FCC took some time and approved it with a 5-0 votes. In the words of Dave Limp, Senior Vice President, Amazon.. 

We have heard so many stories lately about people who are unable to do their job or complete schoolwork because they don’t have reliable internet at home. There are still too many places where broadband access is unreliable or where it doesn’t exist at all. Kuiper will change that. Our $10 billion investment will create jobs and infrastructure around the United States that will help us close this gap. We appreciate the FCC's unanimous, bipartisan support on this issue, and I want to thank Chairman Pai and the rest of the Commission for taking this important first step with us. We’re off to the races.


Amazon is also trying to partner with public and private firms to extend the outcome of Project Kuiper to the maximum possible. With Project Kuiper, Amazon is also planning to backhaul solutions for wireless carriers extending LTE and 5G service to new regions of USA. The development and the testing of Project Kuiper is planned to be carried out in the development facility opening in Redmond, Wash.


Research in the field of satellite constellations is gaining its popularity in recent times. Though Amazon has been approved for setting up satellite constellation recently, SpaceX by Elon Musk has been creating buzz over past few months. OneWeb satellite constellation has also planned to launch as many as 650 satellites initially to form their own satellite constellation.

Amazon is introducing G3 instances specific to accelerate graphic intensive applications, based on Amazon EC2 Accelerated Compute instances. The G3 instances help to achieve the combination of GPU, CPU and host memory for complex workloads. The host memory includes different complex operations like 3D rendering and 3D visualisations.

The G3 instances provides twice the capacities of the most powerful GPU instances available today in every aspect - twice the CPU power, twice the power per GPU, and twice the host memory per GPU. The G3 instances provides the flexibility for complex modelling and 3D visualisation analyses. These capabilities of the G3 instances can be applied in digital image processing, seismic visualisations, geographic analysis visualisations and computer-aided designs.
There are three sizes of G3 instances available - g3.4xlarge, g3.8xlarge, and g3.16xlarge. But, these instances are available across different regions of the US.

Out of the variants of Amazon EC2 G3 instances, G3.16xlarge is the largest one. It consists of four NVIDIA Tesla M60 GPUs, 64 vCPUs using custom Intel Xeon E5-2686v4 (Broadwell) processors, Amazon Elastic Block Store (EBS) optimized hardware, 488 GiB of host memory, and Enhanced Networking using the Amazon EC2 Elastic Network Adaptor. The G3 instances are the first-of-its-kind, equipped with the capabilities of supporting NVIDIA GRID Virtual Workstation. Also, the G3 instances support streaming for four 4k monitors. In terms of hardware encoding, they support up to 10 High Efficiency Video Coding (HEVC) H.265 1080p30 streams for faster video frame processing. In other words, they support up to 18 H.264 1080p30 streams per GPU for faster video frame processing and improved image fidelity.

When compared with software, we are not that forward in terms of hardware. Amazon has recently introduced EC2 F1, the computing instance with Field Programmable Gate Arrays (FPGAs).
Amazon EC2 F1 instances
An FPGA is just like a black box - it consists of "inlets" and "outlets". The FPGA integrated circuit can be programmed, strictly speaking "configured", by the customer or a designer, based upon the specifications. The Amazon EC2 F1 is the architecture based on FPGAs that replicates a given hardware for performance acceleration of an application. The F1 instance are handy to program and is available with all the tools you need to develop, simulate, debug, and compile a given hardware acceleration code. It also comes with FPGA developer AMI and Hardware Developer Kit (HDK), that helps the developer make better and efficient hardware.
Using the F1 instance is easy - actually, it holds only three steps.

  • Design and Development of FPGA, based upon the specifications
  • Registering it as an Amazon FPGA Image (AFI)
  • Deployment of the image onto the F1 instance

The advantage of EC2 F1 lies in reusability of the AFI. It can be reused as many times, across many F1 instances as you like. It is capable of holding the same performance.
Amazon has launched the F1 instances in two instance sizes - F1.2xlarge and F1.16xlarge, that include up to eight FPGAs per instance. The F1 instances are fabricated with 16nm Xilinx UltraScale Plus FPGA. In terms of logic elements, each of these FPGAs are designed
to hold 2.5 million logic elements. The hardware capabilities of the F1 instance include 64GB DDR4 ECC protected memory, with a dedicated PCIe x16 connection and 6,800 DSP engines. Acquiring on-demand instances for F1 is same as that of the other EC2 instances. However on-demand, you need not change the AMI; it still can be reused.

Benefits of Amazon EC2 F1 implementation:
Quick deployment of custom hardware accelerations. As mentioned earlier, it is easier to deploy the images onto the F1 instances. Also, the F1 instances can have one or more AFIs associated with them. This helps you to run multiple hardware accelerations on the same instance without degrading the performance of the hardware acceleration code.
Predictable performance. All the FPGAs available on the F1 instance can communicate at a data rate of 12GBps, all of them connected through a dedicated PCI express fabric. This helps the instance to deliver consistent performance, throughout.
Changing the economics of FPGAs. The Amazon EC2 F1 eliminates the expenses for specialised hardware, as F1 can run several instances at a time. Also, this reduces the cost for deployment.
Using the existing FPGA algorithms. Though the approach for customised hardware has changed, there will not be much change in the existing FPGA algorithms. They can be used as is, with minor modifications.
