The Brown-Roberts-Wells (BRW) Arc System can be compared to spatial navigation because both utilize the concept of direction to and spatial location of a point in space by referencing to a horizontal angle (azimuth) and a vertical angle (declination) relative to the horizon. The BRW system also permits the determination of the distance from a reference surface of the arc system to the point (target). The methods of determining these parameters are explained in detail with illustrations.
布朗-罗伯茨-韦尔斯（BRW）弧形系统可与空间导航相比较，因为两者都通过参照相对于地平线的水平角（方位角）和垂直角（倾角）来利用指向空间中某一点的方向概念以及该点的空间位置。BRW系统还允许确定从弧形系统的参考面到该点（目标）的距离。文中配有插图详细解释了确定这些参数的方法。
