New Technology 1598 Channels IMU South Galaxy G7 Gnss Tracker

Short Description:

Galaxy G7 is equipped with a high-speed 5G full netcom module, which supports the latest 5G communication network and gives the RTKs high speed information interaction and wider expansion space in the big data era. Based on intelligent PPP dial up technology, Galaxy G7 realizes automatic dialing in real-time and keeps online during working.

FarLink Protocol

Galaxy G7 adopts an intemal radio with 3W maximum transmission powerto achieve the typical working range as 15km through "Far-link" protocol.  The transmission bandwidth becomes large, which perfectly solves the problem of large data volume of multiple constellations transmission.  And the powerconsumption can reduce about 60% in the same amount of data transmission compare to the traditional RTK.

It is not a dream to achieve 15km working distance by using the inbuilt radio.

Touch Screen

HD 1.54 inch color LCD touch screen with high brightness and low power consumption is more suitable forfield work, which is convenient and efficient to complete touch settings, information browsing, function settings.

Slink & RTK XTRa

Base on the RTX global services, Galaxy G7 is able to achieve the goal of precise single-point positioning without a reference, the positioning is no more constrained by terrain environment, such as mountain, wasteland, desert, island, fixed solution isl generally available as long as the GNSS constellations are visible.

Moreover, RTK XTRa technology which is derived from RTX services, it can extend RTK positioning for several minutes while the RTK primary source of correction stream isl interrupted or not available, it really makes RTK bright anywhere.

The 'Fast' IMU

Galaxy G7 is integrated with a new generation IMU module thatit only needs 2-5sofshaking receiver to complete the initialization, and the maximum tiltcompensation angle can be 60 degree. it can ignore magnetic interference whileRTK receiver works in such a magnetic environment. This professional IMU modulecan keep the tilt effect for about 40s if RTK receiver stays on a point without moving.
IMU is an electronic unit which records angular velocity and linear accelerationdata which is fed into a central processing unit for data interpreting and logging. lWhen the RTK receiver moves, and then it will record the data and send back to thereceiver for calculating to output the corrected result of position.


Built-in 64GB solid-state storage, which can meet most needs of measurement works. And the feature of cyclic storage helps receiver to automatically remove thel previous files while there is not enough space in the memory, with this excellentl performance, data storage can last almost 4 years based on 5s sampling interval.l And the design of embedded memory chip can ensure the safety of measurement data.


Innovative "dual RTK engine algorithm technology" to achieve secondary coordinate check and calculation, effectively avoiding the problem of fake coordinates, morereliable coordinate accuracy and higher stability.
