POS Series
Accurate full six degrees of freedom Position and Orientation solution for multibeamPOS Series GNSS and inertial navigation system 2-in-1 combined heading and attitude measuring system is independently developed by Hydro-Tech. It was widely used to survey high precision position, heading and attitude of marine platform. The main features are small size, light weight and high precision. POS system comprises of one PCS main unit, one IMU and 2 GNSS antennas. POS Series are suitable for small boat and unmanned vehicle.
Features
- Support post processing to enhance measuring accuracy.
- 1PPS Output realize high-precision timing.
- Output 3 position and attitude data at the same time if needed.
- Support output all kinds of mainstream general data protocol and compatible with various devices.
- Capable to install in various environment and convenient for integration clients.
- Comprehensive electromagnetic compatibility and waterproof sealing design can adapt to harsh environments.
- Highest to 200Hz attitude data output.
