C-Nav2050 The C-Nav2050 survey GNSS
receiver has expanded
capabilities including RTK, 1PPS
output, etc. As with the model C-
Nav2000, the C-Nav2050 is a 10-
channel, dual frequency,
precision GNSS receiver, with
two additional channels for receiving SBAS signals and an L-
Band demodulator for reception of C-Nav subscription
signals. Maximum data output rate is 50Hz and Position
Velocity Time (PVT) data can output at 25Hz. Two 115kbps
serial ports are available. For more information, go to

C-Nav3050 The C-Nav3050survey GNSS receiver has expanded
capabilities including RTK, 1PPS output, etc. As with other
C-Nav receivers, the C-Nav3050 includes dual frequency,
precision GNSS receiver, with two additional channels for
receiving SBAS signals and an L-Band demodulator for
reception of C-Nav subscription signals. For more

Correction Signal The Correction Signal-to-Noise ratio. This graph is only
available with the C-Nav system.
Correction Type The type or source of differential corrections being applied to
the GNSS receiver.
Course True The course computed by the GNSS receiver.
Differential Age The time in seconds since the GNSS unit received the last
differential correction update.
Differential GPS A technique for improving GPS solution accuracy by
reducing the error based on signals received at a known
location. Single point code positioning with pseudorange
corrections are applied from simultaneous observations at
the known position. One to ten meter accuracy is typical.
