Abstract: Based on coordinates differential modes, using Portable GPS Receiver by near-real time process, the positioning precision is about ±5 m. It can be used in forest to do many positioning. Position test to be done under crown measuring more than 4 satellites by synchronous measure, positioning precision is less than ±5 m. When measure time is more than 20 minutes. In addition, why differential-positioning precision is better has been analyzed.
