In mid-1974 a test was made in the Gulf of Mexico of a LaCoste and Romberg inertial system for the measurement of the Eötvös correction for shipboard gravity meters. Since the system is designed for operation with satellite navigation, inertial velocities were updated at 2- to 3-hour intervals, using Lorac information because no satellite information was available. Two types of comparison were made between the inertial and Lorac data. One comparison was the rms difference between results from the two methods—0.46 knot, which corresponds to 3.0 mgal at a latitude of 30 degrees. The other comparison related to noise which could be mistaken for anomalies of interest in oil exploration. The comparison indicated that such noise in the inertial data was only about one third that in the Lorac data.

The Cost

A GPS/inertial navigation system design scheme is introduced. Combination of DSP and FPGA is used on the navigation board, and micro inertial navigation measuring element --ADIS16405 is used to sample required navigation data. DSP mainly implements navigation calculating based on navigation data, and realizes different navigation algorithms; FPGA in the system plays centeral control role, and not only samples IMU and GPS data, but also synchronize IMU and GPS in the real time, and preprocess and packet the navigation data. This paper also introduces the design of the software on FPGA. Practice proves that the scheme is feasible, and achieves the good balance between the cost, reliability and efficiency.

Measuring Unit

To improve the reliability and accuracy of navigation solution, the integration of the satellite navigation receiver with the inertial navigation system is used. These systems have complementary characteristics. An important part of the combined systems is the integration algorithm, which largely determines the final characteristics. The synthesis of such an algorithm for velocity, attitude and the errors of the inertial measuring unit estimation has been carried out. The algorithm is implemented in the software of the prototype of the inertial-satellite navigation system. The results of the experimental evaluation of algorithm’s characteristics for automotive dynamics are shown.
