We use the latest Trimble R8-2 GNSS GPS receiver. The Trimble® R8-2 GNSS System is a multi-channel, multi-frequency GNSS (Global Navigation Satellite System) receiver, antenna, and data-link radio combined in one compact unit. It contains Trimble R-Track technology to support all GPS signals, including the new L2C signal and the coming L5 signal of GPS Modernization. It also supports GLONASS. Data is collected by a TSC3 data recorder.
The Trimble TSC3 is designed for use with GPS and optical total stations. It comes with Microsoft Windows Mobile software for the Pocket PC operating system and runs a range of Trimble field software. Used with field software such as Trimble Survey Controller, the controller can collect and manage GPS and optical data files by simply switching the controller between sensors. It has a changeable cap to allow use with removable media such as memory cards, GPRS, GPS and cameras. The TSC3 controller’s integrated Bluetooth wireless technology eliminates cable hassles and speeds set up. Rover use becomes completely cable free when used with an advanced GPS system.
The Trimble S6 Total Station cable-free surveying instrument is our selected theodolite. MagDrive servo technology gives the unit highly integrated servos and angle sensors to increase speed and accuracy. It silently turns the instrument at speeds of more than 100º/s to provide smooth control for precision pointing. Highly integrated servos and angle sensors increase speed and accuracy. The Trimble S6 also features SurePoint accuracy assurance for consistent and reliable positioning accuracy. SurePoint automatically corrects pointing and measurements in difficult conditions, guarding against the sinking, vibration and handling that can affect an instrument after setup. MultiTrack technology combines passive prism tracking with active Target ID to provide flexibility and performance. It will lock and track a variety of conventional prisms to ranges over 500m and allows the instrument to be used in a range of surveying tasks. With the active Target ID option, users will find and lock to the correct target. Surveyors can use multiple prisms on a site and lock onto the one they need, saving time by eliminating false target locks. The Trimble S6 also has Direct Reflex (DR) technology, which allows measurement without a prism to over 300m. It provides safe, accurate and fast measurements of hard-to-reach or unsafe targets.
