  here is a link on configuring the TSC2 for internet directly from Keynets website.

  With my little knowledge on GPS survey, the theory behind is the same. It does not matter what equipment you are using. Surely with 20 years experience one should be able tackle this one.
  
  In trying to answer this question. You can't use a GPS receiver as a standalone for high accuracy survey unless you doing static survey which will require post processing. Other than that you must have a reference station in a form of your own base station, continuous operating reference station 'CORS' single base or CORS network. CORS is basically a base station operating 24 hours 365 days and mostly provided by government agencies.

  Anthony... profile says he's a licensed Surveyor in NJ with 20 years experience. I don't understand that.

    Ted to clarify, I have been surveying since I was 14, in addition to being a licensed land surveyor I am also a licensed professional engineer.  

    The reason for my inquiry was because I have used Leica equipment in the past and now I have a Trimble R8 unit.  I figured that I must be missing some setting on my collector.  I was hoping someone would be able to point me in the right direction.  

    I understand all of the accuracy discrepencies.  I am setting up to use the rover as a standalone unit that will connect via a phone modem in real time to a network of base stations.  The problem I believe that I am having is that the unit is looking to be paired with the base station instead of connecting to the network

      I can help get you setup with this. Where are you located and which vrs network were you previously using with the Leica receiver?
      Who is your phone service provider?
      Trimble tsc2 or 3?
      Access or survey controller?
      Version?

      You have to go to the Bluetooth settings in the controller and connect your cell phone.  There is a very minor difference from the normal rover config, but It escapes me right now.  I think  its turn off the internal radio.   Go to Trimbles Web site and query the knowledge base under support and you could find what you need there

  I agree with Kevin 100%

  Don't take this the wrong way.  But if you haven't been trained in the different setup options for this type of equipment - you shouldn't be operating it in the field yet. 

  The three main (different) ways GPS rovers can operate are;

  a) as a sub-meter rover, depending on the equipment specifics, this can be done in real-time or by collecting position data in the field and then running a post-processing correction in the office.

  b) as a rover linked in real-time via a UHF/VFH radio modem to a static base station.  This will allow the user to obtain cm level accuracy in real-time

  c) as a rover linked in real-time to a network of base stations via a cell phone modem.  This will also allow the user to obtain cm level accuracy in real-time.

  My main point is that the responsible use and prerequisite knowledge of any piece of survey equipment, from Gurley Transit to VS based GPS rovers to Laser scanners,  is a MUST!!

  Go back the class room and ask for at least quick 2-hour lesson from your supplier or a fellow surveyor with adequate knowledge of the equipment used and proper techniques.

  Good Luck

    Yes, training is essential because there are so many ways to get accidentally poor positions from a GPS receiver.

  I've used the R8's before. You can use it as a standalone receiver but your accuracy is going to be crap. Useful for getting to within a few feet a point.
