Description
Horizon-505 MRU
The Vectory Sensor Systems Horizon-505 is a high accuracy, general-purpose Motion Reference Unit (MRU) providing accurate roll, pitch and heave measurements for singlebeam and shallow water multibeam systems. The MRU includes serial RS232/485 output as well as optional Ethernet.
High Accuracy
The Horizon-505 MRU uses the very latest in MEMS technology as the core sensing elements. Low-noise gyroscopes ensure that roll and pitch outputs have excellent accuracy. This, coupled with very high-stability accelerometers gives a very stable heave performance.
Attractive price
With Vectory Sensor Systems proprietary inertial sensor fusion algorithm, the gyros and accelerometer data is fused in the optimal way, giving excellent roll, pitch and heave performance at a very affordable price.
Phase free heave
The phase-free heave output gives a heave measurement free of phase shifts induced by real-time heave filtering and provides both improved heave response and lower settling times after turns. The phase-free heave output can also be used as a delayed QC of real-time heave.
Several output formats possible
The Horizon-505 MRU supports RS232, RS485 and RS422 outputs as standard. Feel free to contact us, using the form on the right, if you require another output format, such as Ethernet. We would be happy to implement your interface requirements in our sensor.
