The EPOCH 25 L1/L2 RTK GPS System provides robust field performance for rugged surveying conditions. Spectra Precision GPS technology for accurate and reliable real-time positioning is ideal for topographic surveying and setout. Survey Pro software is the ideal field software for EPOCH 25, providing the option of a fast, one-person surveying solution.

A system includes the base and rover EPOCH 25 L1/L2 GPS antenna and receiver, plus a short- or long-range Pacific Crest radio modem. To complete the system, you'll need a data collector. You can buy a bundle that includes a TDS Recon 200 or 400 with Survey Pro GPS, or use a TDS Ranger or Recon that you already own. All components are built for outdoor rugged environments in any weather.

The EPOCH 25 is a highly productive measurement solution, allowing the user to collect topographic data and stake layout detail. The system operates without line-of-sight between points, and it can operate anytime, in any weather, thereby offering much greater productivity over traditional optical surveying techniques.

The EPOCH 25 offers high-quality measurement results in several modes including RTK and Static by using advanced L1/L2 GPS technology.

L1/L2 antenna
The EPOCH 25 antenna is robust and rugged - designed to handle drops up to 6 feet (2 meters), weather extremes and more. It limits signal interference ("multipath"), providing you with an accurate reading every time.
