About this file
This document outlines the salient characteristics for two total stations and related surveying accessories required by the US Geological Survey South Atlantic Water Science Center in Norcross, Georgia. The equipment must meet specified accuracy, measurement, display, and operating requirements. The total stations should have a range of 1.5m to 300m with a 5cm x 5cm reflector and 1.5m to 5000m with a single prism. Additional requirements include Bluetooth capability, 512MB RAM with 4GB flash memory, angle measurement accuracy of 1" horizontal and 0.3mgon vertical, operating temperature range of -20C to 50C, and Windows Embedded Compact 7 operating system. The solicitation also specifies requirements for tripods, prism poles, prism assemblies, prism systems, and accessories that must be met. The related federal contract opportunity is solicitation number 140G0123Q0232 for a Trimble C5 1" total station or equal, issued by the Department of Interior US Geological Survey Office of Acquisitions and Grants.

Salient Characteristics
The USGS South Atlantic Water Science Center in Norcross, GA needs to purchase two Total Stations and related accessories. This equipment will be used for surveying gage datums for streamgages and wells, sensors deployed during hurricanes, and indirect flow measurements. It is imperative that the accuracy level of the surveying equipment meet or exceed the requirements below.
