GPS SURVEYING

What is GPS?

GPS is a satellite-based radio navigation system developed and operated by the U.S. Department
of Defence (DOD). GPS permits land, sea, and airborne users to determine their
three-dimensional position, velocity, and time 24 hours a day, in all weather, anywhere in
the world with a precision and accuracy far better than other radio navigation systems available
today or in the foreseeable future.

The GPS concept of operation is based upon satellite ranging. Users figure their position on the
earth by measuring their distance from the group of satellites in space. The satellites act as precise reference points.

Each GPS satellite transmits an accurate position and time signal. The user's receiver measures
the time delay for the signal to reach the receiver, which is the direct measure of the apparent
range to the satellite. Measurements collected simultaneously from four satellites are processed
to solve for the three dimensions of position, velocity and time.

Why complete an as-built GPS survey of your golf course?

  • Provides the course superintendent with a detailed layout of all features relevant to the course: fairways, greens, tee boxes, water, sand traps, irrigation, yardage markers, cart paths and any other requested landmarks.
  • Detailed geographic data can help the course superintendent reduce costs related to grounds maintenance such as fertilizing, spraying and irrigation by integrating your sprinkler control
    system using GPS data.
  • Provides the superintendent/grounds personnel with accurate course measurement data: area (ft2) of greens, fairways, tees, bunkers, hazards, buildings or other required landmarks.
  • An excellent marketing tool for use in on-line demos, brochures, scorecards and member
    recruiting materials.
  • A powerful planning tool for course design & layout changes.
  • The digital course data can be easily integrated with an irrigation central control system such
    as Toro’s SitePro or Rain Bird’s MAXI.
  • Course data can be easily integrated with a cart-mounted GPS “Pace of Play” or tracking
    system like UpLink or ProShot.
