Spectra Precision EPOCH GNSS and GPS Systems
Spectra Precision EPOCH GNSS and GPS Systems are proven, ultra-rugged field solutions designed especially for tough surveying conditions. EPOCH systems include a GPS antenna and receiver, data collector and software. All components—from the antenna to the data collector—are built for outdoor rugged environments in any weather. Whether you need an L1 GPS, an L1/L2 RTK GPS or a GNSS solution, Spectra Precision has an affordable option for you.

EPOCH 35 GNSS System
The Spectra Precision EPOCH 35 GNSS system uses highly accurate GPS and GLONASS technology for cadastral, topographic, control, stakeout and other precision survey applications. The EPOCH 35 is an integrated, customizable GNSS system that includes a base receiver, rover receiver, choice of short- or long-range radio modem and a choice of a TDS Recon, Nomad or Ranger data collector running TDS Survey Pro field software. The EPOCH 35 GNSS rover features integrated Bluetooth capability, an internal radio modem and battery.

EPOCH 25 L1/L2 RTK GPS
A real-time system, the EPOCH 25 includes the base and rover L1/L2 GPS antenna and receiver, plus a short- or long-range Pacific Crest radio modem. To complete the system, you can buy a bundle that includes a TDS Ranger, Nomad or Recon with either Survey Pro Basic or Survey Pro GPS, or use a TDS data collector that you already own. Two choices of office software are available for data transfer and management.

EPOCH 10 L1 GPS
The EPOCH 10 System includes an L1 GPS receiver and antenna, a TDS Recon data collector with field software plus Survey Office software for post-processing. The robust L1 GPS antenna, in conjunction with the GPS receiver, resists unwanted signal interference. The EPOCH 10 System delivers superior satellite tracking, faster measuring, optimal precision and lower power usage.

TDS Data Collectors
Spectra Precision EPOCH GPS and GNSS Systems include a TDS data collector for maximum performance in the field. An EPOCH 10 System calls for a TDS Recon and the EPOCH 25 System can work with a Ranger, a Nomad or a Recon.
