A90 GNSS RTK Receiver

Key Features

Multi-constellation satellite tracked
The world's fifth-generation GNSS baseband chip TIANQIN, integrating 800 super channels, supporting multi-satellite system full-band satellite signal reception.

Athena core GNSS engine

Running Athena core GNSS engine offering improved initialization times, robustness in difficult environments, performance over long baselines and under scintillation.

Atlas

The receiver can receive our new GNSS global corrections service delivered via L-band satellite and internet to abtain centimeter-level positioning accuracy.


				The A90 ZH Extreme Edition is equipped with a new generation of high- precision positioning boards, 800 super channels, supporting 4-satellites full-band satellite signal reception, and fully supports the fourth- generation GNSS positioning technology.Support “aRTK” technology, maintain a fixed resolution for a period of time in the case of a differential data link interruption.
	IMU Tilt Survey Newest IMU Tilt Survey technology, New algorithm, no need calibration. Using fusion positioning technology, built-in high-precision IMU inertial navigation module, patented IMU inertial navigation and GNSS fusion positioning algorithm, Support 400Hz positioning data output, tilt 60 degrees positioning accuracy 2cm, can do tilt measurement, Surveying at any time.
				Dual Batteries Dual insurance Dual battery + dual battery compartment double insurance design, unique ingenuity, battery self- contained power intelligent detection chip, remaining power, one click know!
	As solid as a rock High purity magnesium alloy material + independent closed space capsule design. Make independent loops between different RF modules. Minimize internal crosstalk, the internal noise control of the instrument reaches the world's top level.
