汽車、火車、艦船、飛機等運動載體的位置和姿態不斷的在變化，要保持與衛星的通訊聯系和接收衛星視頻等信號，就必須採用衛星天線穩定跟蹤平臺系統。 -
If we tracked satellite by the tradition narrow beam antenna, that should caused the jumping tracking between multi - aircraft. that is difficult to achieve by the immense antenna boot and the follow - up system. using digital beam forming realize aircraft target tracking and controlling should be best means to resolve this problem
隨著我國多星測控系統的發展，在一個測控站作用范圍內將出現多星，同時要求地面站對多星同時進行跟蹤測控；如果採用傳統的窄波束天線對目標進行跟蹤測控，必然導致天線在多個飛行器之間進行跳動跟蹤，這對于龐大的天線引導、伺服系統來說難以實現，採用數字波束對飛行器目標進行跟蹤測控是解決此問題的最好方法。 -
