GNSS/GPS/RTK Systems 

 

 

高精度GPS区别于手持GPS的主要特点除了精度差异外，使用方法和配置也存在较大差异，有CORS（单基站CORS，就是只有一个连续运行参考站）网络的地区，测绘单外采购单套GPS接收机即可使用，只需每年向当地测绘局缴纳一定的数据接入费用即可，没有CORS网络的地区，可以选择一套带电台的基准站来充当连续运行参考站，一套基站可以配一套移动站使用，也可连接多套移动站使用，具体GPS接收机(蘑菇头)采购数量由客户根据工程需要自行决定。以上报价为产品单套GPS（蘑菇头）单价，有特殊输入输出语言需求的客户提前告知，不同语言版本的产品由于销售地区差异，工厂定价政策差异较大，具体语言，采购数量和具体蘑菇头配置请电询。
