Looking ahead of the 1990s, one could observe a very rapid expansion of the global market in satellite communication into personal communication and new mobile satellite services, such as Personal Conversation System (PCS) and Mobile Satellite Services (MSS) respectively, Low Earth Orbit (LEO) satellite systems, Global Positioning System (GPS) navigation, and new direct broadcast satellite services. LEO satellite services were introduced towards the end of the 1990s, and the growth depended on competitive factors. The conventional Fixed Satellite Services (FSS) and Maritime Mobile Satellite Services (MMSS) grew steadily but not as before.
Optical fiber cables, now forming a greater part of this conversation revolution throughout the world, severely challenged the fixed satellite services. Very high data rates, similar to High Dynamic Range (HDR) graphics, which require greater than 155Mb per second of data transfer, which required excellent signal conditioning, were being carried by the fiber optics cables.
Fiber optic cables have a better performance than satellites, having much less time delay in transmission. It was a time when satellite services needed to prove their advantage on HDR applications and networking, having more modest data rates, for example, T1=1.5Mb per second. A T-1 line consists of 24 individual channels, … Read the rest
