Integrated project management platform

Relying on Internet technology, Zhongwei project management platform is specially designed for project managers and project surveyors to make their collaboration more efficient, accurate and easy: it has 6 modules and more than 20 functions to achieve project lifecycle management.

*Field operators can upload and download data, automatically back up job data and job trajectory, and solve future worries
*With the help of the platform, project managers can manage data, personnel, progress, results and quality to achieve the integration of internal and external work

Core motherboard --Powered by Novatel

*Excellent signal processing model to achieve effective repair of satellite signals and improve RTK fixation effect
*Strong satellite signal checking capability ensures that the dispersion error of RTK data acquisition is within 6mm
*Mainboard multi-mode static data receiving algorithm, with higher urban static measurement accuracy
*Powerful satellite signal tracking capability, which can achieve 99.99% reliable initialization within 8s
*Advanced satellite locking technology ensures the stability of the data link and achieves efficient fixed solution
*The new elevation fitting technology adapts to the challenge of high elevation error in the west and low elevation error in the east of the country, and the elevation accuracy is better

Swiss Manufacturing Process

*The connecting part of the host is fastened with 18 bolts. The arc length between each bolt is the same as π, and the torque is the same to ensure the balance and stability of the instrument.
*The upper and lower parts of the host are sealed physically without chemical adhesives or rubber rings, so as to avoid the deterioration of waterproof performance caused by material aging.
*The mainframe is made of special materials, which reduces the weight of the instrument and increases the strength of the instrument by 30%
The host reaches the dust-proof and waterproof grade of IP68 and has longer durability

New internal/external radio

The newly upgraded internal and external radio of Wei zG20; The operation distance will be greatly extended once the station is erected; It is prohibited to move the station for many times, making the operation easier.
