1 Introduction
The F7 GNSS receiver removes barriers to portability without sacrificing performance.
Featuring full GNSS technology, it offers best-in-class GNSS signal tracking even in a harsh
environment, enabling GNSS surveying beyond usual constraints. The F7 GNSS incorporates
the latest innovations such as an inertial module (IMU) providing automatic pole-tilt
compensation in a very compact design.
1.1 Safety Information
1.1.1 Warnings and Cautions
An absence of specific alerts does not mean that there are no safety risks involved.
A Warning or Caution information is intended to minimize the risk of personal injury and/or
damage to the equipment.
WARNING - A Warning alerts you to a potential misused or wrong setting of the
equipment.
CAUTION - A Caution alerts you to a possible risk of serious injury to your person
and/or damage to the equipment.
1.2 Regulations and Safety
The receivers contain a built-in wireless modem for signal communication through Bluetooth®
wireless technology or through external communication datalink. Regulations regarding the
use of the wireless modem vary greatly from country to country. In some countries, the unit

2 Getting Started with F7
2.1 About the Receiver
The new F7 GNSS receiver offers integrated IMU-RTK technology to provide a robust and
accurate GNSS positioning in any circumstances. Unlike the standard MEMS based GNSS
receivers, the F7 GNSS IMU-RTK combines state-of-the-art GNSS RTK engine, calibration-free
professional IMU sensor and advanced GNSS tracking capabilities. Survey projects are
achieved with high productivity and reliability pushing the boundaries of conventional GNSS
RTK survey.
The receiver can be used as the part of an RTK GNSS system with EFIX eField software.
Moreover, user can download the GNSS data that recorded in the internal memory of receiver
to a computer.
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. Serial ports and connectors are
located on the bottom of the unit.

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.
(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 9
folders. The “push_log” folder is used to save the log files, and the other 8 folders represent
different logging sessions and are used for store static data.

Getting Started with F7
EFIX F7 GNSS USER GUIDE | 2021-1 Page | 19
(5) Double click the folder that you have configured to store the static data, you will see the
folder(s) created by the F7 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 (hcn 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.
Notes: For hcn 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.
