*Technology/Project Introduction (Background, status quo, characteristics, etc.): i80 GNSS receiver is a bold evolution in the field of RTK. The developer strives to design a more refined and powerful small intelligent receiver with the smallest volume in China and a diameter ≤310px; The fuselage has a built-in motherboard, core control board, MEMS system, radio module, antenna, smart dual batteries, network module, Bluetooth module, and Wi-Fi module, which gather the essence in every inch, challenging the technical limits of GNSS receivers. The FT-LED display is easier to see clearly under strong light.  

*Main technical indicators: . The i80's built-in tilt sensing MEMS system can calculate accurate actual offset based on the heading angle and tilt angle when tilting within 30°, so that the accuracy under tilting can also meet high-precision measurement requirements, allowing users to measure it without considering centering the middle rod bubble in actual measurement. The tilt angle is within 30° and the accuracy is 1 to 3 centimeters. As long as you have a smartphone with Wi-Fi in your hand, you can easily manage the i80 instead of your notebook, and set the host information through the Wi-Fi mobile phone web page function. The i80 and smartphone can realize two-way transmission when connected to each other, and simultaneously realize data transmission under the multi-point link state. The data transmission chain is more stable and the transmission speed is faster, making your measurement work more efficient from now on. The i80 can be connected to any Mobile device with Wi-Fi function (including smartphones and PDAs) for data transmission, reading and setting, providing users with a third connection method in addition to Bluetooth and serial port. The TSC3 uses a 59-key full keyboard design, including all numeric and alphabetical keys. It has passed the U.S. military MIL-STD-810G waterproof, dustproof and drop-resistant standards.  

*Current application situation: automatically log in to the cloud platform when booting up, detect the latest firmware version of the host, compare it with its own firmware version, and display the comparison information on the handheld side. Users can choose whether to upgrade according to needs, realizing a more intelligent and humane remote function service. Products and services cover high-precision geodesic GNSS receivers, GIS data acquisition terminals, wireless data transmission equipment, water measurement products, combined navigation systems, deformation monitoring systems, system integration, mobile surveying and other solutions, as well as related software development and applications.  

*Application prospects of "civilian joining the army" or "military conversion": Products are widely used in military equipment supporting facilities, and military units are welcome to cooperate in development and application.
