The i90 GNSS receiver integrates professional LMU-RTK technology to
provide a robust andaccurate positioning. in any circumstances. It
combines state-of-the-art GNSS RTK engine, acalibration-free
high-end MU sensor and advanced GNSS tracking capabilities to
dramaticallyincrease RTK availability and reliability.The 90
automatic pole-tilt compensation boosts survey and stakeout speed
by up to 30%Construction and land surveying projects are achieved
with high productivity and reliabilitypushing the boundaries of
conventional GNSS RTK survey.

Company Information
Shanghai Galxy International Trade company, Ltd. combining with
developing, researching and producing. Our company is located in
Pudong Developing Zone, and has two subsidiary companies: Shanghai
Galaxy International Trade Co., Ltd. and Mato Opto-electrical
High-tech Company. Our company has researching center and factory
in Changzhou.
Our main products are as following: total station, electronic
theodolite, automatic level, laser level, rotation laser, GPS,
distance laser sensor and accessories, such as tripod, prism, pole,
staff and USB cable for total station. Our company designs software
for many domestic and oversea factories, for example, Boif, TJOP,
Stanley, and Cst-Berger. We have powerful capacity in technical
research, and the products we designed have advanced technology and
steady performance. The non-prism total station and the absolute
coding measure instrument we developed and produced have very
competitive points in the measure instrument market.
We expect that we could cooperate with more business partners from
all over the world. In addition, we can do OEM service for
companies or dealers that want to find better producers in China.
Our goal is to produce the best surveying instruments in the world.
Our target is to globalize the market, internationalize the quality
and maximize the profit!
