GPS Surveying
Thompson Conn Limited has the ability to collect positional data through the use of the
Global Positioning System (GPS). Using high precision GPS data collectors
Thompson Conn is able to create a control network by collecting GPS data by the
static method (collecting many positions over a period of time). This
control network could then be the basis for further positioning such as layout
for building or road construction, or as control for a boundary or topographic survey.
Thompson Conn is also able to perform surveys for construction and topographic
surveys using Real Time Kinematics methods (RTK) where one GPS receiver broadcasts
corrections that are received by another GPS receiver to get an instant position.
Thompson Conn Limited also has access to Code Division Multiple Access (CDMA)
corrections that are broadcasted by Leica and their partners (of which
Thompson Conn is one) over the internet and received using cell modems attached
to the GPS receiver. The CDMA configuration allows Thompson Conn to
perform instant surveys without having to tie up a receiver as an RTK base
station, allowing 2 or more receivers to collect data more efficiently,
decreasing the time and cost of performing the survey.
