PRODUCT DESCRIPTION
A90 GNSS Surveying System from FOIF has revolutionized control surveys, topographic data collection and construction surveying. A90 performs more advanced features such as smart design and WIFI monitoring. You will find many modifications in this instrument different from other GNSS products. 8GB internal memory for standard and include an optional TF card with maximum 32G which should be enough for your whole project.
Main Functions
*Compact design, more productive
*Professional GNSS statellites tracked simultaneously (GPS, Glonass, Galileo, Beidou)
*When the pole is tilted in 30 degrees, A90 still could get the right point data by automatic correct system (IMU tiltsurvey)
*Applies WIFI connection to realize WebUI control designed to modify settings and monitor the receiver status
*Bundled Android field software brings a big change in user experience and accessibility

FAQ
Q:How to turn off voice broadcast of receiver?
A: a. Enter the WEBUI, find the voice switch in the settings page and turn it off.
b. Controller Software→Device→Device Setting, turn off the "enable voice", and click"ok"
Q: Can the base station and rover station be interchangeable?
A: The difference between the rover station and the base station is that the accessories are different, the function and hardware configuration are the same.You can use the controller to choose the working mode of the device and set it as the base station or rover station.
Q: What is CORS?
A: CORS is called a continuous operating reference station system. It can be understood as a bas e station that is erected at a fixed known point and works continuously for 24 hours and sends its own data to a specific serverthrough the network. The use of CORS operation eliminates the need for a base station, and CORS is equivalent to a base station in a normal network operation.
