What kind of survey equipment is used when staking? - used gps survey equipment
I'm an equipment operator, and I always wondered what sort of survey team in the creation of centers and lines of the game used, and how. I know from what I see are the GPS antennas, but I wonder why they are necessary.

Used Gps Survey Equipment What Kind Of Survey Equipment Is Used When Staking?

Surveyors can use any number of support tools. The tool most commonly used conventional survey is a total station. This is a two-person operation, if you are a person with the total station itself and the other person is the man to the bar (a bar) with a reflector. The whole station is set to a known reference point, and review is used as reference and a check. The man at the bar go to areas of interest and the total station is used, is played by the coordinates of the position of the bar man.
GPS has become a tool that was used in place of a total station. A GPS receiver (base), where the total station and GPS receiver in place of the straw man (Rover) could be used. Rover receiver reads the same issues arising from the people.
GPS offers the following advantages compared to traditional methods of investigation:
1) the traditional survey tools, it is not a line of sight between the instrument and the bar man, the true, GPS
2) a person can. Or you can have a second person in a dryth mobile receiver, and [presumably] the job done faster
3) the accuracy is not degraded due to the weather
4) In general, the work can be done faster with GPS
However, there are restrictions on the GPS, where conventional tools can be better suited:
1) line of sight between the base and vehicles are not binding, but is required between each receiver and the GPS satellites. Consequently, the survey-grade GPS can be done at home
GPS receiver 2) is usually more expensive
3) the traditional investigative methods are faster for smaller jobs
Of course, I have greatly simplified this point, but we hope that you get the idea.
purple band has a good job of answering this question. he (she) is the only person I saw on Yahoo Answers so far (besides me) who really knows what they are talking about when it comes to GPS.
the only thing that could give the answer for him, but will not very complicated, that, depending on where it may be possible to prevent the establishment of a database of GPS. Because some states, including also began to me, their own GPS reference system and build up data in real time to deliver a specific IP address. Therefore, a user may only need a wireless Internet connection to receive, RTK (real-time kinematic) corrections. so that only one vehicle unit (receiver / antenna / data collector / Cellular) is a modem or mobile phone all that is needed in these cases.
