If it is only used for general tourism, then hundreds of pieces of GPS is enough, go to the computer city to see, there must be sold, or go to your city to look at the outdoor store
Q:How to use the handheld GPS whole watershed investigation
Some people think that the use of critical state to solve the most value should be cautious, we must first distinguish the relationship between the two states
Q:I would like to ask the GPS handset and GPS receiver (Surveying and mapping qualification application needs) is there a difference?
GPS handheld GPS operating manual, GPS receiver is to receive satellite signals, GPS consists of two components.
Q:How to set the handheld GPS related parameters and coordinate conversion parameters throughout the country
Two. To coordinate the coordinate data of the control points obtained provide technical support unit of Beijing Unistrong companies around the branch responsible person to calculate the coordinate transformation parameters conversion parameters, or to obtain their own conversion conversion software. After the conversion parameters are calculated by the prompt input handheld GPS. Only after such a setup, after all the soil in the region when the coordinates of the GPS read out the coordinates of the point for the Beijing 54 coordinates.
Q:Fuxin coordinates with the mapping of the seven parameters are what ah
Handheld GPS has not been used, you can find three known control points, try to solve.
Q:I am a handheld GPS precision is low, how to use to be able to improve certain accuracy
If the carrier phase measurement function is not available, you have the maximum accuracy of GPS accuracy of 1-10This can only improve the observation environment using SBAS and other ways to improve the accuracy
Q:I am a handheld GPS precision is low, how to use to be able to improve certain accuracy.
Look at the maximum accuracy of GPSIf the difference accuracy can reach 1cm you can connect CORS single base station and other network RTK way to achieve the corresponding accuracy
Q:What do you need to test for GPS?
As a high-tech product, GPS has a very complex technical parameters. However, as people's living standards improved rapidly, more and more ordinary people began to pay attention to the positioning and navigation tools originated from the military. Because the convenience it brings is unprecedented. In order to let everyone out of all the technical parameters of GPS receiver, no longer confused at the time of purchase, the author selected six of the most important technical indicators, one by one to explain to you. 1 parallel channels on the market most of the GPS receiver is a 8 channel, 12 channel, the 16 channel, which allows them to continuously track the information of each satellite. Some GPS devices only have 2 to 5 parallel channel receiving satellite signals, because the average of 8 satellites are visible, which means that the GPS receiver must visit each of the satellites in order to obtain information about each satellite. All of our products are in Shenzhen channel 16 channel, multi-channel parallel GPS receiver, including the advantages of rapid cold start and initialization of satellite information, but also in the forest area can have a better reception. General 12 channel receiver does not require an external antenna, unless you are in a bad environment conditions such as closed space, such as the cabin, the car. 2 the sensitivity of the GPS satellite signal to the ground has been very weak, as well as ground wireless communication clutter interference. The lowest traceable signal strength of the GPS receiver determines how much useful signal is received. A GPS receiver with a lower minimum tracking signal strength has a higher sensitivity, and can receive more available satellites under bad conditions
Q:How to hand GPS eTrex H data to the computer
Computer installed on the MapSource software, connect the data cable, upload waypoints and tracks can be!
Q:Ask how to select a google satellite map into a handheld Area GPS
If it refers to a professional portable handheld GPS, please ignore this answer.
We have been committed to innovation in GNSS since 1999. To date, we have established a first-class GNSS simulation laboratory, research and development center, in addition to four of our own workshops. With excellent hardware facilities, senior engineers and well-trained technicians, we can design and manufacture different types of GNess products and GIS data collector as well as GIS surveyors, and more.
