Title: Today’s Satellite Broadband Landscape: LEOs, MEOs, GEOs and Megaconstellations

Date: August 18, 2021

Time: 10:00am PT / 1:00pm ET

Presented by: Dr. Whitney Q. Lohmeyer, Assistant Professor of Engineering, Olin College of Engineering

Abstract:
In a connected society, it is challenging to fathom that the year 2019 marked the first year in which more than half the world had access to the Internet. For decades, but in particular the past ten years, tremendous efforts from governments and the private sector have been made to bring more individuals online, and to realize the economic and arguably social benefits of a connected culture. In this session, Whitney Lohmeyer, the first engineer at OneWeb, will discuss the technological progress and system design of the satellite communications sector, focusing on today’s planned and deployed satellite networks. These will include low earth orbit (LEO) constellations like OneWeb, SpaceX’s Starlink, and Amazon’s Kuiper, along with medium earth orbit (MEO) networks like SES’ mPower and Mangata Networks, as well as geostationary (GEO) networks like Viasat and Echostar (HughesNet). In addition to system design, technical challenges like coexistence issues amongst LEO megaconstellations, terrestrial and radio astronomy services (RAS) will be discussed.
