Low Earth Orbit (LEO) satellites operate at between 500 kilometers (310 miles) and 2,000 kilometers above the Earth’s surface. That’s far less than is typical for the 36,000 km height of geostationary satellites, the traditional home of communications satellites. The main advantage of the lower orbit is lower latency.
LEO satellites are not new. Most of the Earth’s approximately 2,000 active satellites are already in LEO. What’s new is the sheer scale of recent proposals, driven by technological developments in smaller satellites and reusable rockets, which have dramatically brought down costs. Typically, these satellites weigh (sometimes substantially) less than 500kg. A small satellite has stringent energy constraints, which is challenged by transmission over long distances. Small spacecraft s must have active lifetimes of up to five years and so contain photo-voltaic solar panels to generate electrical energy from the sunlight.
Sending metadata up into the cloud as opposed to data that is traceable back to a specific individual.
Some data are better made locally, in real-time, as opposed to being sent to the cloud for processing.
A fraction of the data being sent to the cloud is being mined effectively for analysis... but it is all being stored, which costs the enterprise a significant amount of money.
The integration of robust data analytics...
The compound annual growth rate (CAGR) of LEO satellites is predicted to be 20% from today to 2025.

The desire to develop quick and affordable access to space means that design approaches that would once be considered unthinkable for space are at the core of many of these platforms:
Effectively this world is shifting to “good enough” electronics. Companies are focusing on performance, cost, footprint, weight, and power. That said, these systems must be reliable. There is increasing concern about large areas of this space becoming unusable for decades if systems crash into others, either due to faults occurring during normal operation or if the planned disposal strategy goes awry.
The Lynx part in this reliability story relates to providing a software framework that guarantees determinism. These systems are running multiple applications and operating systems on a high performance, multi-core processor. These functions demand a real-time response when they occur, and the systems must have a path to certification. Creators of satellites can harness the proven DO-178 certified operating system (OS) and separation kernel technology that leaders and innovators in the aerospace industry have deployed at scale for years.
As a platform provider, LYNX acknowledges the need to provide adaptive platforms that can be tuned by developers to manage complexity. Lynx has created a LYNX MOSA.ic for UAVs and Satellites Product which combines a set of Lynx and 3rd party technologies together in a way where customers know that their own software development is underpinned with a proven software platform.
