About the EPOCH 50 GNSS system
The EPOCH 50 GNSS receiver uses an internal GNSS antenna and is designed for
GNSS surveying applications.
The GNSS receiver consists of the receiver with integrated GNSS antenna, internal
Pacific Crest ADL transceiver, 0 dB gain UHF antenna, and internal Li-Ion battery. The
system can also be used with an external radio modem for longer range use.
Alternatively, the receiver can operate for short-range work with the internal ADL
radio. All EPOCH 50 receivers are equipped with internal Tx/Rx radio modems. When
using radios to transmit, Spectra Precision strongly recommends that you use an
external battery for power to increase operational time.
An LED screen on the receiver allow you to monitor the satellite tracking, radio
reception, and power. Bluetooth
®
technology in the receiver provides cable-free
communications between receiver and controller.
The receiver provides high precision multiple correlator GNSS pseudorange
measurements, unfiltered, unsmoothed pseudorange measurement data for low noise,
low multipath error, low time domain correlation, and high dynamic response.
The receiver provides 220 channels:
•
GPS: Simultaneous L1 C/A, L2E, L2C, L5
•
GLONASS: Simultaneous L1 C/A, L1 P, L2 C/A (GLONASS M Only), L2 P
•
