Transformational Satellite (Tsat) Communications System : 9781249326526 : 11 Sep 2012 : The Transformational Communications Office's (TCO) 17 December 2003 report states, "The current SATCOM and data relay systems are unable to meet future bandwidth demands. They lack capacity, in both aggregate data rate and the number of users they can support. . . . Furthermore, the life expectancies of the existing space segments and much of their associated terminal and management segments do not extend beyond the 2010-2015 time frame." These shortfalls and the military's insatiable demand for bandwidth led to the creation of the Department of Defense's (DOD) TSAT. TSAT's five-satellite constellation will be capable of delivering advanced capabilities to the war fighter via 8,000 radio frequency (RF) links and between 20 and 50 laser communication (lasercom) links. These advanced capabilities will deliver significant communications bandwidth by incorporating advanced laser and RF technologies, sof
