摘　　要：GPS定位技术具有全天侯、高效率、高精度且GPS点间无需通视、作用距离远等特点 ,在矿区控制测量中进行了运用尝试 ,尤其在测区高等级控制点比较稀少 ,这些控制点又不得不采用的情况下 ,可采用偏心观测。本次实验就是有针对性地选择不同边长、不同的网形进行GPS偏心观测、偏心归算。在通过精度分析 ,提出了最适合GPS偏心观测的网形。As the orientation technology of GPS has the character of all-weather, high-efficiency, high-precision etc., it is used experimentally in the Department of Survey and Drawing. We have come to realize the good reason in controlling survey in coal mines, but the high-grade controlled point is fewer and we have no choice but to use these points, so we use the bias survey. This experiment is aimed at choosing different length, different net form to carry on GPS bias survey and returning calculation. By analysis of precision we offer the best net form and length.
