![]() Since LEO systems operate closer to atmosphere in a much harsher environment than GEO, the interference of radiation and atmospheric drag can have an adverse impact on their life. The ground system also becomes more complex and costlier. LEO satellites operate close to earth at <1500 km of altitude, so their coverage is much smaller (circa 2000-3000km diameter), hence the need for constellation for continuous coverage. ![]() They offer best options for scalability, thereby helping addressing limitations of terrestrial networks. Due to their smaller size, they incur less cost of manufacturing. They are also characterized by minimum propagation delay (latency) of about 10ms. ![]() Since LEO satellites move closer to earth, they can offer superior signal strength, and require less power for transmission. More importantly, LEO is gaining traction in the wireless satellite broadband because it offers significant improvements in speed and latency. ![]()
