Description
For the most accurate heading data in harsh, extreme latitudes.
SeaTRAX-85º is for vessels operating in polar regions, where standard magnetic compasses are prone to errors and fluctuations due to the Earth’s magnetic field.
- SeaTRAX-85º is the first towed array heading sensor engineered to deliver the most accurate heading data in harsh, extreme latitudes. Its highly-sensitive magnetometer readings are refined by state-of-the-art algorithms that calibrate for magnetic distortion and compensate for all tilt angles.
- It delivers serial digital outputs of precise, reliable heading, pitch, roll, magnetic sensor and accelerometer readings.
- At less than half the size of other heading sensors, SeaTRAX-85º will fit almost everywhere. And because it consumes only one tenth of the power, it’s ideal for use in long missions and in harsh environments.
- Unlike standard sensors used in many towed arrays, SeaTRAX-85º delivers heading accuracies of 0.25º in the Arctic Circle – previously unheard of in a tiny digital magnetic compass module. Even at 85° latitude, it delivers better than 1.5 ° heading accuracy. So you get clear survey images even in the Arctic Ocean.
- It works beautifully in lower latitudes as well.
- SeaTRAX-85º is ideal for applications including towed arrays, anti-submarine warfare, seismic streamers, and military exploration and operations in the Arctic and Antarctic regions.
