Alpha 4i Product Review

Crafted with nano-material and a wave-transparent top cover, the Alpha 4i features an aluminum alloy-reinforced housing. It comes with a 316 molybdenum steel threaded connector and a 5/8 pin interface.

All-satellites full-frequency 8cm positioning antenna

The Alpha 4i features a full-frequency positioning antenna that supports all satellites. For the first time, it reduces the traditional 11cm antenna diameter to 8cm without compromising any signal strength. Utilizing high-frequency microwave radiation carriers and electromagnetic band gap technology, along with a design that incorporates four feed points and a high-gain widebeam, the Alpha 4i can quickly achieve a fixed solution even in low elevation and complex situations.

IMU tilt sensor

Fast initialization IMU, support tilt measurement with 2CM accuracy when tilt angle 60°.

The newest generation of global positioning SoC chip

Equipped with the latest NebulasIV radio frequency baseband and high-precision algorithm, the cutting-edge SoC chip supports computation algorithms for all satellite frequencies. With independent frequency point tracking and 60 dB narrow-band anti-interference, it can maintain positioning even in the absence of a satellite signal.

Embedded real-time operating system (RTOS)

For the first time, Alpha 4i incorporates a military-grade real-time operating system (RTOS). This ensures full compatibility with RTK development requirements and enhances its suitability for IoT application scenarios. RTOS systems are widely employed in spacecraft, missiles, robots, Tmall Elf, and other IoT devices due to their lower power consumption.
