GPS/INS Integration for Vehicle Navigation based on INS Error Analysis in Kalman Filtering

The Global Positioning System (GPS) and an Inertial Navigation System (INS) are two basic navigation systems. Due to their complementary characters in many aspects, a GPS/INS integrated navigation system has been a hot research topic in the recent decade. The Micro Electrical Mechanical Sensors (MEMS) successfully solved the problems of price, size and weight with the traditional INS. Therefore...

INS/GPS Tightly Coupled Approach Using an INS Error Predictor

In this paper, the tightly coupled INS/GPS integration system using an INS error predictor is proposed for improving the filter estimation performance when fewer than four satellites are tracked. The suggested error predictor stores the estimated position error in case of tracking above four satellites and calculates the initial error components for prediction of Schuler position error when few...

Ins and outs of Cdc14

Virus takes the actin express V iruses typically hitchhike around the cytoplasm on microtubules. Ohkawa et al. reveal that one type of virus can travel within the cell using actin fi laments. Once baculoviruses break into a cell, they need a lift to the nucleus so their genetic material can be copied. However, these viruses don’t require microtubules for the journey. Ohkawa et al. investigated ...

Ins and Outs of E2Fs

Precise control of the mitotic cell cycle is a critical feature of eukaryotic life. In humans, mutations in cell cycle regulatory genes lead to the uncontrolled cell proliferation and tumor formation associated with the most dreaded of all diseases, cancer. E2F transcription factors are key components of an elaborate mechanism of cell cycle control in higher eukaryotes. For example, the promote...
