3 Outstanding Technologies
All-satellites full-frequency 8cm positioning antenna
Carries all-satellites full-frequency positioning antenna, shortens the traditional 11cm antenna diameter to 8cm, without losing any signal. With High frequency microwave radiation carrier and electromagnetic band gap Technology, combined four feed points phase center design and high-gain wide beam, Alpha 4i can get instant fixed solution in low elevation and complicated situations.
The latest generation of global positioning SoC chip
Integrated with the latest generation NebulasIV radio frequency baseband and high-precision algorithm, the latest SoC chip supports all-satellites full-frequency computation algorithms. Independent frequency point tracking and 60 dB narrow band anti-interference, continue to positioning even lose satellite signal.
Embedded real-time operating system RTOS
Embedded military class real-time operating system RTOS, Alpha 4i can fully satisfy RTK development requirement and is more compatible with IoT application scenario. RTOS system is widely used in spacecrafts, missiles, robots, and other IoT devices for its lower power consumption, smaller volume and real-time instant response.
Fully Compatible Transceiver Internal UHF Radio
—
Supports various working modes in global regions Support 410-470MHz full frequency band Compatible with various RTK protocols Output stable solution to 3km base station surveying area Compatible with 35W external radio
90° Inertial Navigation
—

Fast initialization IMU, support tilt measurement with 2CM accuracy when tilt angle 60°. IMU can still work in tilt angle 90° even 120°

DiMap
—
DiMap has been greatly upgraded with various measurement modes that cater to users’ needs. Users can view and check the data while the measuring program is under way. The DiMap, which offers services for RTK, is professional, intelligent, and user-friendly.
