Navigation systems in neurosurgery
Voprosy neirokhirurgii imeni N.N. Burdenko, 2016 When preparing the review, we analyzed publications available at the Medline database; a total of 1,083 publications related to the review's subject were analyzed. After more careful analysis, we selected 117 publications devoted to the development of neuronavigation in craniocerebral surgery, historical prerequisites of neuronavigation emergence ...

Unambiguous Tracking Technique Based on Shape Code for BOC Signals
IEEE Access, 2020 The multiple peaks characteristic of binary offset carrier (BOC) autocorrelation function (ACF) makes ambiguity easy to be generated. There are some methods to eliminate ambiguity, but for higher-order BOC Signal, it will sacrifice signal energy or ...

A Fusion Methodology to Bridge GPS Outages for INS/GPS Integrated Navigation System
IEEE Access, 2019 The performance of an inertial navigation system (INS) and global positioning system (GPS) integrated navigation system is reduced during GPS outages. To bridge GPS outages, a fusion methodology to provide pseudo GPS position information is proposed. The
