With a hi-tech, fully integrated design, the conveniently sized A90 is one of the most flexible device for any gps measuring task. Built-in Linux operating system, pre-loaded multiple smart applications such as IMU, electronic bubble calibration, NFC and voice DIY.
Overview On NEW GENERATION A90 CORS GNSS Receiver
New generation receiver--- Compact, lightweight and handling! Work anywhere and anytime!


Top Features:
1), Smart Design, more productive
With the increasing demand for smart-design GNSS, to develop the receiver featured with miniaturization turns into our new goal until today it comes true. It is completely no doubt that small size and light weight design can greatly alleviate general field work and improve productivity a lot.
2), Brand new idea
In terms of cellular mobile and wireless system, we tend to introduce more and more creativities into our product. Besides a set of bluetooth, wireless radio and mobile network, we bring in the WIFI function which quite broaden data communications for GNSS.
3), Excellent performance:Embedded with high-sensitivity GNSS module , A90 can implement massive surveys:RTK, DGPS (SBAS) , Static, etc.
4), Professional GNSS satellites tracked simultaneously (GPS, GLONASS,GALILEO, BeiDou)
5), Automatic date collection during centering
6), Support the IMU function. When the pole 60 degrees,A90 still could get the right point bate by automatic correct system
7), Applies WIFI connection to realize WebUI control designed to modify settings and monitor the receiver status
8), Bundled Android field software brings a big changes in user experience and accessibility
9),FOIF A90 gps gnss rtk with Hemisphere board P40 board 800 channels support IMU max 60 degree tilt survey.
