Q:What is the difference between industrial GPS handset and mobile navigation

5, strong battery life, is a major feature of professional GPS, Garmin handset General of dry batteries can be used more than ten hours, while the mobile phone GPS on GPS also can use a few hours, if you open the GPS in general about 3 hours will be over.6, supporting different software. Professional GPS handheld opportunities related to the PC end of the data processing software, this software can achieve the acquisition of data processing, as well as the application of data collection. The phone GPS can only navigation, and navigation is only a small part of the GPS function.I simply say these, this is my personal summary of the difference, if you have what is not clear can exchange. Want to help you.

Q:Handheld GPS buried in the soil there is a signal

It depends on how deep you buried the darker the GPS signal, and must ensure that the GPS antenna upward, the above can not be covered with metal objects

Q:What is the difference between the phone's GPS and professional handheld GPS features and differences?

But because it is a built-in or external Bluetooth GPS so the accuracy is not good at least a few meters there will be a gap drift phenomenon is simple said you drive open what is displayed on the screen of your car has been in the car to go outside for a while after a while back lane unstable and power consumption a larger say to you if you are a fresh hand if there is WM or Symbian system that will buy a mobile phone Bluetooth GPS module in Internet search navigation software can be installed navigation

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. For the 12 channel receiver, if you are in the last position near the location of the cold start time is 30 seconds to 5 minutes, hot start is usually 5 to 40 seconds, and for the 2 channel receiver, most of the cold start more than 15 minutes, hot start 2 to 5 minutes. The positioning accuracy of the positioning accuracy of 4 which is obtained in the case of no WAAS/EGNOS conclusion, rather than most of the GPS receiver specification of the positioning accuracy, can look at the test report of others so before the purchase of GPS, now on the market with 12 channel GPS receiver error level is generally not more than 30 meters, height error not more than 50 meters, the average error is about 15 meters. Due to the use of the module, our product positioning error is about 10 meters,

Q:How about the accuracy of the GPS handset?

Zhonghaida Q1:2 zhonghaida Q5:1 meters; meters; zhonghaida Q6: decimeter; zhonghaida Q8 cm;

Q:Verify the accuracy of the GPS device to buy back, the way is to use Android under the'gps state 'software, to test the accuracy of real-time single point positioning.1 with two sets of the same Android Tablet Computer (custom machine, type of bad) in the same position for receiving, find that the accuracy is the same (software, are 1-2 meters), but the position would be poor 10 meters or more. It's in the same place.The 2 one is the Android tablet computer, a mobile phone is HTC G10, also received together in the same position, find that the accuracy is not the same as (the latter 20 meters or so), but also may be about 10 meters position difference.The accuracy of this GPS device can reach 1-2 meters, while the same location in real-time single point positioning error of 10 meters, a reasonable explanation.

Oh the single point positioning accuracy is about 10 meters, but also have a great relationship with the environment around you, if in the city, the accuracy of twenty meters are possible, if the open place, outside. Ten meters should not be a problem. Whether you use a professional measurement RTK or ordinary navigation handheld machine, single point positioning accuracy can reach 1-2 meters of the machine I is not met, if you see where I wish to share with me, thank you. Can only say that the use of professional measurement RTK will certainly be higher than the navigation accuracy of GPS single point oh

Q:Handheld GPS, the measurement of arable land, fixed point and circle test, which is more accurate,

So for you to measure the area, some of the 3cm point error surrounded by the graphics area and some millimeter level point error surrounded by the graphics area is not much difference.

Q:How to use the handheld GPS whole watershed investigation

Therefore, it is an important method to solve the maximum value in physics by solving the maximum and minimum values of the physical quantity by the critical state.
