Summary

This chapter focuses on the satellite as a platform for provision of satellite-based services. It introduces the key parameters that describe the motion of these satellites around the Earth, and allow us to determine their orbital period and instantaneous position. The chapter focuses on the principal types of orbit in use, of which the geostationary orbit is, perhaps, the most widely known. Our notion of satellites relates primarily to objects orbiting the Earth sustained by their momentum, located well above the drag of the Earth's atmosphere. However, at lower altitudes, the use of ‘surrogate’ satellites, in the form of High-Altitude Platforms (HAPs), is gaining significant interest for servicing smaller coverage areas at lower cost and shorter timescales, and potentially with higher performance.
