Product Details

ER-7660 Economical FOG Inertial Navigation System


Economical FOG Inertial Navigation System built-in total temperature 0.3 º/ h high-precision closed-loop fiber optic gyroscope, 100 ug high precision quartz accelerometer. It supports BD function mobile mapping level multi-mode multi-frequency GNSS receiver, which can realize dynamic rapid alignment or GNSS double antenna auxiliary fast high precision orientation, which can be up to 0.1º.

ER-7660 FOG INSsupport GNSS/odometer/DVL/barometric altitude meter and other external sensors. It has good scalability, by using multi-sensor data fusion technology combining inertial measurement and etc, it also can make the system has been greatly improve regional adaptability and robustness; Products with pure gyro drift free function independently. At the same time, it can be in the absence of any external auxiliary, which can realize the infinite time course hold, especially suitable for unmanned aerial vehicle (UAV), and other kinds of underwater vehicle unmanned aircraft navigation position.

To meet the mobile street, marine surveying, mapping surveying, mapping field application requirements, matching with original data storage, the level of surveying, mapping navigation post-processing software, users can match it according to requirements.
