The antenna can be used on a range pole, mounted on a vehicle, installed as a base station or extended high above tree canopy to provide the optimal solution for everyday tasks. Using the 4700 system, surveyors can collect data for topographic maps, stake-out construction sites, perform boundary, seismic and geodetic control surveys, as well as photogrammetric work.

The announcement was made at FIG XXI -- The 1998 International Surveying Congress.

"Today's surveyors require more flexible solutions to satisfy their changing needs and increase productivity," said Joseph Paiva, vice president of Trimble's Land Surveying Group. "The 4700 draws upon the company's 14 years of surveying experience to provide the industry's best hardware form factors and easy-to-use GPS applications software."

GPS Total Station 4700

Trimble's GPS Total Station 4700 incorporates four major components: the 4700 GPS receiver with an integrated radio modem, separate GPS and radio antennae, the rugged System Controller (TSC1o) data collector with Survey Controllero software, and easy-to-use Trimble Survey Officeo software.

At the heart of the GPS Total Station 4700 is a small, highly-integrated GPS receiver and radio modem. Weighing only 2.7 pounds (1.2. kilograms), the receiver can be carried in a backpack or hip pack. The 4700 receiver utilizes the latest in Trimble dual-frequency, real-time technology. Users can get centimeter accuracy and receive position updates five times per second while moving.

The TSC1 -- Lightweight, Ergonomic Handheld for Surveying

Trimble's TSC1 is an extremely rugged, yet easy-to-use, handheld unit for system control and data logging. It has an easy-to-read graphical display, providing icons for control and readout of critical survey information. The full alphanumeric keyboard was designed for harsh weather conditions, with key spacing and size optimized for gloves or operation with one hand. The large internal memory of the TSC1 can be supplemented by an optional PCMCIA card for virtually unlimited data storage and rapid exchange of data with a PC. The new operating system on the TSC1 has been optimized for speed and multi-tasking operations. Users can now run several surveying tasks at the same time, without any interruption of satellite lock. The TSC1 operates with all Trimble surveying receivers.
