Q:Trouble Hongkong friends come in! About Hongkong buy handheld GPS!
Basically what questions are like this, there are few domestic brands, low precision did not see any big price advantage, but high precision or cheaper than abroad, you belong to the individual leisure estimates do not need to read.
Q:Ask how to select a google satellite map into a handheld Area GPS
The ordinary mobile phone GPS, can install Orville interactive map support pre download any regional satellite map, support for offline use
Q:Handheld GPS, the measurement of arable land, fixed point and circle test, which is more accurate,
If the measurement point is only the case, the dynamic GPS is now the general error can be guaranteed within 3cm, the total station can be guaranteed to the millimeter.
Q:Handheld GPS charge is not into electricity what is the reason
3, restore the factory settings to see whether the system is.4, the battery damage, can replace the battery repair.
Q:I would like to ask the outdoor adventure GPS are required to have what functions, a good GPS all aspects of the parameters are?
Fifth elements: the terrain map is the main project of outdoor sports climbing, mountain climbing is very exhausting, we usually do a plan will be completed on schedule, a good plan should be to our destination in the manual run out before. And if you want to do this, it must be on the road difficult to have a correct anticipation. But this time, with the terrain map GPS can come in handy, the mountains and the altitude of the understanding, we need to know about these sections spend much time and energy. And the general GPS map, is unable to meet the needs. So we'd better buy a map with contour terrain data of professional grade GPS, make your own outdoor journey do in our hands.

Q:Seeking the similarities and differences between RTK and GPS
GPS: is the satellite positioning system in general, narrow sense refers to the GPS satellite, and the narrow sense refers to all can receive GPS signal equipment; RTK refers to the dynamic real time difference measurement, it also refers to the difference can be used for real-time dynamic measurement equipment. The difference between the two measurements from speaking: GPS contains RTK, also includes some precision lower grade equipment, such as the Garmin handset, handset, GPS meter level navigation etc..
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.
