eFix R1 Overview
The eFix R1 is a high-accuracy and high-performance multi-frequency GNSS RTK and
mapping system professionally designed for surveying fieldwork by GeoSun. With the most
advanced high-precision real-time kinematic positioning technologies, eFix R1 is able to
search and track all the GNSS satellites signal in view so as to provide users with
high-accuracy, high-efficiency and most reliable RTK survey performance. Being an
outstanding assistant and tool in different fields such as electric power, transportation,
agriculture, forestry, and land survey, it can do high-accuracy RTK, wide-range control
survey, construction stakeout, topographic mapping, high accuracy marine survey and etc.
Together with the GeoPro K2 as the standard packaged controller, or with the gPad as an
optional controller, eFix R1 system is the professional RTK while completes the data
collection and processing both during fieldwork, providing powerful and flexible solution
for various GNSS applications. It does greatly improve the fieldwork efficiency.

Note
Although eFix R2 series handheld is made of corrosion-resistant and impact-resistant
materials, this kind of sophisticated instrument still needs careful usage and maintenance.
Please preserve the handheld in dry environment as possible. To improve the stability and
service life, the handheld should avoid being exposed to extreme environment, such as
being used in damp, high temperature, low temperature, corrosive gas or liquid, etc.
To ensure the continuity and quality of the satellite tracking, the space over observation site
should be as open as possible, without large obstacles over 15° elevating angle. To reduce
various electromagnetic interference to GNSS satellite signal, please make sure no strong
electromagnetic interference in 200m range around the observation site, such as TV tower,
microwave station, high-voltage transmission. To avoid or to reduce the multi-path
influence, the site should be set far away from the terrain and ground features where the
electromagnetic wave signal reflection is strong, such as high buildings, large area waters,
etc.
Note:
 This equipment contains ESDS (Electrostatic Discharge Sensitive Device), with level
C of electrostatic anti-interference test. To touch, move, or plug the equipment please
follow the ESD (electro-static discharge) instructions.
 Must be used and preserved in the stipulated temperature range. For details, please
refer to the previous chapter: Technical Specifications。
