Satellite systems include: Satellite networks: A combination of nodes, including satellites, that provides communication between two points on Earth. Communication satellites: Artificial satellites that transmit signals through a transponder, creating a channel between a transmitter and receiver on Earth. Geostationary orbits: Orbits in which a satellite orbits directly over the Earth's equator and completes an orbital period at the same rate as the Earth's rotation. This means the satellite remains in the same position in the sky throughout the day. Galileo: A Global Navigation Satellite System (GNSS) launched in 2016 by the European Space Agency (ESA). Galileo is said to be the first satellite constellation to provide Precise Point Positioning (PPP) by sending direct signals from space. GNSS: A satellite system used for positioning by receiving its satellite signals. GNSS is the generic term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. BeiDou: A satellite navigation system of China made up of 35 satellites that orbit the Earth and transmit precise data. Satellite-Based Augmentation systems: A satellite based differential correction system. Some modern satellites are smaller and more numerous than ever before. They are made up of multiples of 10×10×11 centimeter cubic units, and weigh roughly 3 pounds. These satellites are known as CubeSats, and are named after their dimensions.
Topics include: Satellite Systems, Femtocell Network, Ultra-Wideband Technology, & Wireless Network Multicast.
