Function Features:
Alpha 4i is a new product with Alpha SoC chip,most components of 4i (GNSS module, Wi-Fi, Bluetooth,etc.) are integrated on one circuit board. 4i has lower powerconsumption, and efficiently improves the ability of receivinghigher quality satellites signals.Powerd by the new SoC GNSS board, new generation sensitivity satellite antenna, new ROS platform and GNSS RTK engine, 4i can fully track GPS, GLONASS, BDS, GALILEO, QZSS, SBAS and IRNSS/NAVIC. To obtain centimeter-level positioning in few seconds. Now 4i supports the BeiDou-3, B2b, L-band and BDS-PPP, it can get real-time high-precision positioning even there is no base receiver.
Multiple communication connections:
WiFi, Bluetooth, RTK host network connection, support IGRS pairing, users can choose the connection method according to the specific job, flexible and efficient.
Site elevation:
Various elevation model files, such as triangular nets, are self-built and imported for site elevation staking to facilitate site elevation control.
Background map:
Support SHP, DXF and other user data to add, support offline and online Baidu map display, there are maps and the truth.
** Our workshop located at Malaysia and available spare parts for repairing and maintenance in future.
** We have 25 years experienced engineer to repair and calibrate all type of survey instruments.
