1、Brief introduction
1.1 Overview
GNSS RTK base station integrates high-precision differential ceramic
antenna, GNSS positioning module and integrated 433 data transmission
module. The equipment is highly integrated and easy to apply. It can be quickly
deployed to the application scenarios requiring differential RTK calculation.
RTCM32 international correction data is provided to enable the equipment of the
flow station to carry out RTK calculation.

3、Product Operation
3.1 Power on
Outdoor without blocking environment, provides 5V DC power supply to start
up the device when it is powered on. If the indicator light is on, it means normal
startup.
3.2 Working status description
The status of indicator light, and the red indicator light flashes regularly to
indicate the normal operation of the base station; If the indicator light is not on,
check whether the power supply of the equipment is correct. At the same time,
make sure that the base station is placed in an open field and can receive good
GPS satellite signal. Once the equipment works normally, try not to cut off
power or move the position. Once the power is off or the location is moved, it
may take a long time for the base station equipment to recheck the reference
location.
4、Product application
This product has a built-in high-precision GNSS module for calculation.
RTCM32 correction data is broadcast by the data transmission station. By using
the supporting RTK mobile station equipment to receive correction data, high-
precision positioning calculation can be completed and centimeter-level
precision data can be obtained. It can be used in outdoor GNSS base station
service scenes with high precision.

5、Attention
The erection of the reference station directly
affects the measurement quality of the flow
station. The location of the reference station
has the following requirements:
1. There should be no obstacles in the space above 10 degrees in the
horizontal direction of cut-off height Angle
2. No signal reflectors around, such as large areas of water, large
buildings, etc. And try to avoid traffic arteries, pedestrians interference
3. There should be no strong electromagnetic radiation sources
nearby, such as TV tower, radar TV transmitting antenna, etc., so as
not to cause interference to differential RTK electrical signals, and the
distance shall not be less than 200m
4. The reference station should be located at a relatively high
elevation to facilitate the distance of the radio station
5. The ground is stable, and there should be no shaking during the
use of the base station
6. If a station is set under an object that has great influence on
electromagnetic transmission, such as a tree, the satellite signal
received will be distorted when the receiver works, affecting the
difference quality of RTK and making it difficult for the mobile station
to enter high-precision mode
7. During RTK operation, the reference station is not allowed to move
or shut down and restart, or the system needs to be rectified after
restart
8. Provide a stable power supply to the base station to avoid
fluctuations caused by unstable power supply
