Safety Warnings
The Global Navigation Satellite System (GNSS) comprises several distinct satellite
constellations, each of which is under the jurisdiction of a specific government entity.
These entities bear the sole responsibility for ensuring the accuracy of their respective
systems and for maintaining the integrity of their satellite networks.
Do not rely solely on the device for critical navigation decisions. The GNSS signals
may be affected by atmospheric conditions, satellite availability, signal blockage, etc.
Be aware of the limitations of GNSS accuracy. It provides positioning information
with a certain level of accuracy, but errors (including manual error) and deviations can
occur.
Avoid prolonged exposure to strong magnetic fields, as they may interfere with the
operation of the device and affect its accuracy.
Do not dismantle or modify the device. Any unauthorized modification may result in
malfunction or damage and void the warranty.
Follow all instructions provided in the user manual for proper handling, charging, and
maintenance.

2 Getting Started with Nbase
2.1 About the Receiver
The Nbase GNSS receiver is a professional GNSS base station. The working
performance is close to GNSS receiver with external radio, but user no need to carry
heavy external battery, external radio, and radio antenna. 5W internal radio ensures
that the end user can reach 8km work range. It supports the radio interference
checking technology, judge the radio signal real time, make sure user can select the
most suitable channel to use.
The LCD panel enables user to check satellite-tracking status, internal battery status,
Wi-Fi status, working mode, data logging status and basic receiver information.
Bluetooth and Wi-Fi technology provides cable-free communication between the
receiver and controller.
The receiver can be used as the part of an RTK GNSS system with eField software.
To configure the receiver for performing a wide variety of functions, you can use the
web interface by connecting the receiver with PC or smartphone through Wi-Fi.
2.2 Parts of the Receiver
The operating controls are all located on the front panel. Battery compartment and
SIM card slot are on the bottom. Serial port is located on the bottom of the unit. The

2.7 Downloading Logged Data
Data logging involves the collection of GNSS measurement data over a period at a
static point or points, and subsequent post-processing of the information to accurately
compute baseline information. Data logging using receivers requires access to suitable
GNSS post-processing software such as the eOffice Software.
2.7.1 FTP Download
The procedures of downloading logged data through FTP are as follows:
(1) Switch on the receiver, search its Wi-Fi in the computer and connect.
(2) After the successful connection, open the file manager in the computer and input
“ftp://192.168.1.1” in the address box.
Farnav Nbase GNSS USER GUIDE
| 2026-02 P a g e | 15
(3) Input user name and password, the default user name and password are “ftp”.
(4) Double click the folder “repo_receiver SN” (take 3225804 as example), you will
see folders. The “push_log” folder is used to save the log files, and the "record_1"
folders are used for store static data.
(5) Double click the folder that you have configured to store the static data, you will
see the folder(s) created by the Nbase system automatically and named by the date
which is decide by GPS time when you start to log data.
(6) Select the destination folder and double click it, two folders named as different
data format (ECN and rinex) will be displayed.
(7) Select the data format that you configured to save the static data, you will find the
static raw data.
Farnav Nbase GNSS USER GUIDE
| 2026-02 P a g e | 16
Notes: For ecn files, the name of the file is represented as XXXXXXDDDNN, where
XXXXXX is the SN of the receiver, DDD is day of year, and NN is the recording
session.
WARNING – The static data will be saved in the first logging session, the
“record_1” folder, by default. Old files will be deleted if the storage space is
full. If you configure not to auto delete old files when the memory is low, the
receiver will stop data logging.

a) Auto Rover: The receiver will serve as a rover after this mode is enabled, and
then receive correction data through the working mode set last time.
b) Auto Base: The receiver will serve as a base after this mode is enabled, and
then broadcast correction data based on coordinate inputted by user or
obtained through autonomous positioning automatically.
c) Manual Base: The receiver will serve neither as a base nor a rover after this
mode is enabled. Users need to configure the receiver manually.
Farnav Nbase GNSS USER GUIDE

Users can determine the positioning limit and sampling amount. The positioning limit
falls into two types:
a) Single Solution Coordinates: Collect the coordinates of receiver obtained
through autonomous positioning.
b) Fixed Solution Coordinates: Only collect coordinates of receiver with a fixed
solution.
