Star chain: with stars fixed
Open "Starlink" service, originated from satellite-based PPP (Precision Point Positioning) technology, real-time accuracy can be less than 4cm, convergence time is less than 30 minutes, and dynamic operations are more freedom. 
All-terrain unbounded measurement
Satellites broadcast precise orbit and clock data. Positioning is no longer limited by terrain and distance. Mountains, wastelands, deserts, and islands can acquire known points with stars, and stars can be fixed.
Fully open coordinate system
The satellite-based independent coordinate system can be operated without any known points or parameter conversion during terrain surveying and other mapping operations, and provides a coordinate framework system that can be freely converted or accessed for regional operations.
Smart "star base station"
Broadcast "Starlink" data to simplify setup operations, provide regional operations services, and operate more efficiently and intelligently.
Intelligent platform
Embedded Linux operating system + South smart cloud, the receiver will no longer be an independent hardware device, but a complete intelligent system, combined with the web version of the data cloud service platform, to achieve online registration and other remote management, data interaction services.
Electronic bubble
When checking whether the alignment rod is horizontal, the user does not need to pay attention to the physical bubble of the alignment rod, and the electronic bubble on the manual measurement software accurately displays the leveling state of the alignment rod in real time.
Full-featured internal radio
Send and receive integrated integrated radio stations, fully support mainstream radio communication protocols, realize interconnection with imported products, and switch network relay and radio relay modes.
Network relay mode
The mobile station broadcasts the received network differential signal again through the built-in station and forwards it to other mobile stations for use.
Radio relay mode
The mobile station forwards the received differential radio signal to other mobile stations via the internal radio, greatly extending the radio range.
mobile network
4G full Netcom module, backward compatible, applicable for various signal areas. The new network architecture supports the current mainstream CORS system.
Smart storage
 ● Built-in 8G solid-state storage, and supports external U disk storage
 ● STH, Rinex support multiple formats, sampling frequency up to 50Hz
 ● Support automatic cycle storage, disk full automatic deletion.
 ● Supports one-key smart copy, external U disk directly to copy data directly.
Dual Mode Bluetooth
Equipped with 4.0 standard dual-mode long-distance Bluetooth, compatible with the 2.1 standard at the same time, it can connect handbooks, mobile phones, tablet and other digital products, and the communication distance is farther, giving the user more comfortable homework mode.
WI-FI data link
The first use of WI-FI as a data link, significantly improve the actual measurement results; at the same time with AP hotspot function, any smart terminal can access the receiver to control it.
WebUI management background
Built-in WebUI network user management background, support WI-FI and USB mode access receiver built-in Web management page, real-time monitoring of the host status, free configuration of the host, you can freely configure the host without going around.
High-definition LCD
High-definition 1.54-inch OLED color LCD display, high brightness, low power consumption, more suitable for field work.
