    Abstract: 低地軌道人造衛星組有很多的應用,其中之一是在一定區域內提供定位功能,為了在一定區域內提供定功能,吾人已發展一個方法去設計一套人造衛星組以便確保永遠有四顆人造衛星是可被觀察的,此衛星組將可提供每天二十四小時在良好地理位置的人造衛星組。本文中建議的人造衛星組將可使這區域定位統所提供的定位功能如同GPS所做的一樣。
    There are many applications on the low Earth orbit satellite constellations. One of them is to providing the function of positioning. The positioning function is over certain region. To
    provide a positioning capability over a certain region, a scheme to orbit a sufficient number of satellites to ensure that four are always electronically visible is developed. The planned constellation will provide a minimum the scheme to orbit the satellites is proposed to obtain the Regional Positioning System which can provides the positioning function as the GPS does and the navigation accuracy is given. An numerical example shows that a LEO constellation having 32 satellites can provide the positioning function over the region of the radius of 4800 Km centered at the arbitrary chosen site of 30° Nand 0° E .
