ANF-301B
MEMS North Seeker
The ANF-301B can continuously track and measure changes in inclination, tool face, and azimuth. The product is designed with shock absorption and high-temperature resistance. It enables precise measurement of the carrier’s angular and linear motion parameters even in harsh environments. It can be applied in resource exploration fields such as coal mining and petroleum.
Features
High-temperature operation
Supports zero-bias compensation to maintain heading accuracy over time
Configurable homing time
Supports installation misalignment angle compensation
Adaptability and reliability in harsh dynamic environments
