The developed system for trajectography and positioning proved satisfactory: 1. observed ranges were over the requirements : 6000 m in normal environments were obtained. 2. accuracy is higher than expected: 15 cm error standard deviation or bias was observed by checking at sea by the range measuring system itself the (known) hydrophone positions when transmitting from the towing submarine. 3. reliability is high enough to deliver the requested information for array processing 4. in good environmental (ambient noise) conditions the source level used is low enough to keep the acoustic contamination within an acceptable level.
