M8 Overview
The M8 is a high-accuracy and high-performance multi-frequency GNSS RTK and mapping
system professionally designed for surveying fieldwork by KQ GEO. With the most
advanced high-precision real-time kinematic positioning technologies, M8 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 K8 as the standard packaged controller, M8 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 M8 is made of corrosion-resistant and impact-resistant materials, this kind of
sophisticated instrument still needs careful usage and maintenance. Please preserve it in
dry environment as possible. To improve the stability and service life, the M8 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。
