Outline of Final Research Achievements

For the accuracy and precision improvement of the geodetic observation in the offshore region, low power consumption system for the position and attitude estimation is extremely important. This research achieved (1) development of the low power consumption GNSS continuous observation system for the moored buoy environment and (2) development of new algorithm for the precise and accurate estimation deduced from the 1 GNSS antenna and MEMS gyro. We succeeded to develop the low power consumption GNSS observation system which contain the real-time PPP processing and the GNSS phase data recording with less than 3 W power consumption. We also developed the new algorithm for the attitude determination based on the 1 GNSS antenna and MEMS gyro. Based on our algorithm, we succeeded to estimate the attitude with the accuracy of 0.5, 0.4, and 0.4 degree for the Yaw, Pitch and Roll angle, respectively.
