权重和功率估计的重要性和获得它们的方法进行了讨论。一种方法，足够准确的系统和运载火箭规划的发展。它从转发器数量、寿命、日食服务、射频功率等操作要求以及电池和太阳能电池性能等某些一般技术因素出发，计算阵列功率以及有效载荷和主动力系统的质量。利用这些结果，并区分自旋和体稳卫星，许多通信卫星的回归分析的结果，然后用于确定其他子系统的权重。使用简单的轨道力学来确定推进剂、远地点发动机等的重量，以得出最终的质量估计。如果有可靠的输入数据，这一估计数应精确到5%至10%。
The importance of weight and power estimates and methods for obtaining them are discussed. A method sufficiently accurate for system and launch vehicle planning is developed. It starts from operational requirements such as numbers of transponders, lifetime, eclipse service, radio frequency powers and certain general technology factors such as the performance of batteries and solar cells, and calculates the array power and the masses of the payload and primary power systems. Using these results, and differentiating between spinning and body stabilized satellites, the results of regression analyses on many communication satellites are then used to ascertain the weights of the other subsystems. Simple orbital mechanics are used to determine the weights of propellants, apogee motor, etc., to arrive at a final mass estimate. This estimate should be accurate to between 5 and 10 per cent if reliable input data are available.
