THALES Navigation, Carquefou, France, introduced the 3011 GPS compass. The 3011 is a heading measurement instrument designed to meet the requirements of navigation professionals. The 3011 antenna consists of 2 GPS sensors, each of which is able to acquire 12 satellites. The position of one sensor relative to the other is determined through algorithms – Gyrosky –simultaneously, which results in faster and more accurate determination of a vessel’s course. The 3011 can measure a vessel’s course with an accuracy of 0.5 degrees and is operational in less than 80 seconds after power is supplied. It is operational in less than 15 seconds in signal re-acquisition. It can interface to modern navigation systems such as OVERLAY radar, ARPA radar, automatic pilot and more.
