The service position of HAIGE in the field of Loran-C and “Big Dipper” navigation system is to make the high quality navigation position products. The Loran-C receiver developed by HAIGE can provides 0.25~1.2 nautical mile position accuracy for free sailing, waypoint sailing and route sailing, can automatically memorize and display route, track and waypoint and can correct time difference of Loran-C navigation system. The “Big Dipper” navigation system developed by HAIGE can provides 20m surface position accuracy for free sailing, waypoint sailing and route sailing, transmitting secret digital message, storing waypoint and display route, memorizing position track and equipment parameter and saving message.
