Medium Earth Orbit

O3b's mission

The four additional O3b medium earth orbit (MEO) satellites will augment SES’s existing O3b constellation of 12 satellites to deliver low latency, fibre-like connectivity to people and businesses in the growing mobility, fixed data and government markets. Positioned at an altitude of approximately 8,000km, the O3b MEO satellites are approximately ¼ of the distance from the earth than traditional geostationary (GEO) satellites, which allows to greatly reducing latency. The new Ka-band spacecrafts will enable SES Networks to continue the drive towards digital equality and generate social and economic development by delivering high performance communications anywhere, even in the most remote areas. By scaling the O3b MEO constellation efficiently, SES Networks will be able to offer more capacity, enhanced coverage, increased efficiencies and greater flexibility.
