Preface
V90Plus is a new type of GNSS receiver used for measurement pushed
forward by Hi-Target Brand,used a new design,Magnesium alloy
construction,Linux3.2.0 operating system,Combined gravitational acceleration
sensor, WiFi connectivity, it is a realization of lightweight, intelligent, easy to
use measurement GNSS receiver.
Warning: 1、V90Plus receiver best to use 3G SIM card, if you
still use 2G SIM card to work, affect instrument
performance or operating units caused economic losses, the
company will not be responsible!

Cautions for Use
V90 Plus receiver used Chemical resistance and impact resistance
design ，but we also need sophisticated instruments careful use and
maintenance.
Warning: the receiver shall be in stipulated temperature range
upon using and storage. The detailed requirements are
shown in Chapter V: Technical Parameters —>
Environment.

In order to guarantee the quality of continuous tracking
observation and satellite signals, it is required that the
overhead observation station shall be open, without flaky
barriers above 15° elevating angle; in order to diminish the
interference of electromagnetic wave to GNSS satellite signals,
the observation station shall be free form strong
electromagnetic wave within the range of 200m, such as
television tower, microware station and high-voltage
transmission line; in order to avoid or reduce multipath effect,
the observation station shall be far away from the terrain and
ground features with strong reflection against electromagnetic
wave signal, such as high-rise buildings, waters, etc.
