据报道,设在美国加利福尼亚州的Magnavox控制及工业电子公司(Magnavox Government and Industrial Electronics Company)生产了一种MX1502型的新式轻便卫星定位系统。这种定位系统的出现大大减轻了测量工作人员的劳动强度并大大节省了他们宝贵的工作时间。 该仪器重40余磅,内有微型计算机,可以以5米的绝对误差和1米的相对误差很快地测定出地面上任何一点在三维空间中的位置。 The Magnavox Government and Industrial Electronics Company in California, USA, reportedly produced a new portable satellite positioning system MX1502. The advent of such positioning systems has greatly reduced the labor intensity of measurement staff and greatly saved their valuable working hours. The instrument weighs more than 40 pounds, with a microcomputer, you can quickly determine the position of any point on the ground in three-dimensional space with an absolute error of 5 meters and a relative error of 1 meter.
