Geolocal is a new navigation system conceived and patented in Brazil, whose purpose is to be independent of other global navigation satellite systems (GNSS). It has an ‘inverted-GNSS’ configuration with at least four bases on the ground at known geodesic position coordinates and a repeater in space. Simulations were performed to determine the precision of Geolocal using different quantities and distributions of bases. They showed that this precision is enhanced when the quantity of bases increases, as long as the elevation angles of the new bases included are higher than the average and when the bases are evenly distributed around the repeater, but mainly when the time delay at the repeater is known in advance and when the measurement errors that generate uncertainties are reduced. The position dilution of precision (PDOP) was also calculated, confirming that precision is enhanced by the quantity of bases and by their distribution.

Geolocal – 一种新的地理参考系统：基础分布分析

Geolocal 是一种在巴西构思并获得专利的新型导航系统，其目的是独立于其他全球导航卫星系统 (GNSS)。它具有“倒置GNSS”配置，在已知测地线位置坐标的地面上至少有四个基地，并在空间中有一个中继器。使用不同数量和分布的碱基进行模拟以确定 Geolocal 的精度。他们表明，当碱基数量增加时，只要新碱基的仰角高于平均值，并且碱基均匀分布在中继器周围，这种精度就会提高，但主要是在中继器的时间延迟时是预先知道的，并且当产生不确定性的测量误差减少时。还计算了精度的位置稀释（PDOP），
