Sigma Series GNSS Receiver

JAVAD SIGMA Series GNSS Receiver

The SIGMA series of GNSS receivers from JAVAD GNSS were designed to be versatile for multiple applications requiring RTK, offering options for GNSS heading and roll/pitch from a MEMS IMU.s.



The SIGMA series of GNSS receivers from JAVAD GNSS were designed to be versatile for multiple applications that require RTK, with options for GNSS heading and roll/pitch from a MEMS IMU. With an internal battery, 2 power inputs, and all typical I/O, the SIGMA series of receivers readily serves multiple GNSS configurations.

Featuring integrated cell and radio communications, the receivers can be used as reference stations, with NTRIP caster and server functions to transmit RTCM corrections via TCP or NTRIP.
