Q:Handheld GPS which brand is good
Now GPS can also do handheld measurement accuracy, precision can usually reach decimeter level, the industry there are relatively well-known Huace, professional GPS measurement instrument, high precision of handheld GPS the good.
Q:What do you need to test for GPS?
3 positioning time this means when you restart your GPS receiver, it determines the time required for the current position.

The handset is generally rough field positioning equipment, navigation for mobile phone use, the general size, precision grade m, now can to about 20cm, and can be used for RTK mobile station use (need to access the base station) can reach cm level.Surveying and mapping qualification applications require geodetic measurement equipment, that is, 1.Now domestic GPS, such as the Haida, the south, China, etc. can be measured, not expensive
