EPOCH 35 RTK GNSS System

The EPOCH 35 is a complete GNSS system that includes a base, rover, field software, data collector, and radio. The EPOCH 35 GNSS rover features integrated Bluetooth capability, an internal radio modem and battery. In North America, the system operates with the popular TDS Survey Pro field software. Outside the U.S., the system runs Spectra Precision Field Surveyor. These premiere field software solutions operate on the Spectra Precision Recon or Nomad data collectors.

For RTK surveying, the base system may include a choice of radio modems that provide either a long- or short-range data link from the base to the rover. In addition, Network RTK is also supported by simply connecting to an external data capable cellular modem. Back at the office, surveyors can use the Spectra Precision Office Software for post-processing and quality control.

The EPOCH 35 GNSS system provides high-quality results in several survey modes including RTK and Static. The system operates without line-of-sight between points, and can be used in any weather. Built especially for tough surveying conditions, the compact and lightweight EPOCH 35 GNSS system can handle drops, extreme temperatures, dirt, and water.

I am also agree with imran aziz tunio (irrigation engineer) but suggest that some error should be rectified from RTK, because we are curently used this instrument and error occured in 0.3 cm. So please check it accuracy again.......... John H. David - 30/12/2011 - 18:23

I am fully agreed with Imran Aziz Tunio Drag philip - 04/12/2011 - 15:00

RTK systems use a single base station receiver and a number of mobile units. The base station re-broadcasts the phase of the carrier that it measured, and the mobile units compare their own phase measurements with the ones received from the base station. There are several ways to transmit a correction signal from base station to mobile station. The most popular way to achieve real-time, low-cost signal transmission is to use a radio modem, typically in the UHF band. In most countries, certain frequencies are allocated specifically for RTK purposes. Most land survey equipment has a built-in UHF band radio modem as a standard option.
