Deep Gaussian Processes (DGPs) are probabilistic deep models obtained by stacking multiple layers implemented through Gaussian Processes (GPs). Although attractive from a theoretical point of view, learning DGPs poses some significant computational challenges that arguably hinder their application to a wider variety of problems for which Deep Neural Networks (DNNs) are the preferred choice. We ...

A differential global positioning system (DGPS) is one of the most widely used augmentation systems for a low-cost L1 (1575.42 MHz) single-frequency GPS receiver. The positioning accuracy of a low-cost GPS receiver decreases because of the spatial decorrelation between the reference station (RS) of the DGPS and the users. Hence, a network real-time kinematic (RTK) solution is used to reduce the...

Distinguishing patterns represent strong distinguishing knowledge and are very useful for constructing powerful, accurate and robust classifiers. The distinguishing graph patterns(DGPs) are able to capture structure differences between any two categories of graph datasets. Whereas, few previous studies worked on the discovery of DGPs. In this paper, as the first, we study the problem of mining ...

The Korean nationwide differential global positioning system (NDGPS) reference station transmits a global positioning system (GPS) enhancement signal using minimum shift keying modulation with a 200 bps data rate. The ocean-based DGPS covers the service area of 100 NM with 300 W output power; on the other hand, the land-based DGPS transmits the output power of 500 W, which covers the service ar...

The differential global positioning system (DGPS) transmits a GPS enhancement signal using a top-loaded monopole antenna in the medium frequency range. The top-loaded antenna in the medium frequency band can attain a radiation efficiency on the order of 10%. The antenna ground plane characteristics affect the antenna radiation efficiency. To improve the radiation efficiency, it is necessary to ...

In this paper we propose an efficient authentication and integrity scheme to support DGPS corrections using the RTCM protocol, such that the identified vulnerabilities in DGPS are mitigated. The proposed scheme is based on the TESLA broadcast protocol with modifications that make it suitable for the bandwidth and processor constrained environment of marine DGPS.

The goal o f the work presented in this paper is to provide mobile platforms within our compus with a GPS based data service capable of supporting precise outdoor navigation. This can be achieved by providing campus-wide access to real time Differential GPS (DGPS) data. As a result, we designed and implemented a three-tier distributed system that provides Internet data links between remote DGPS...

new advances in geomatics and communications technologies are enabling the development of automated auscultation system for structure monitoring. in particular, differential gps (dgps) technique allows real-time monitoring of structures with millimetre accuracy after an appropriate mathematical treatment. the results of real-time dgps monitoring of a pilot dam over 15 months are presented and c...

The augmentation of DGPS with ground-based GPS transmitters (pseudolites, or PLs) was investigated. A simulation analysis was conducted to determine the effects of PL augmentation on DGPS availability, accuracy and reliability measures, using various constant mask angles and a " real-world " horizon (measured at Lake Okanagan, British Columbia) plus a simulated obstruction. Field tests in the m...
