A hybrid error modeling for MEMS IMU in integrated GPS/INS navigation system
Tập 16 - Trang 1-12 - 2018
Continuity of accurate navigational data for intelligent transportation
applications has been widely provided by utilizing low-cost navigation systems
through integrating GPS with micro-electro-mechanical-system (MEMS) inertial
sensors. To achieve the required accuracy, augmentation of Kalman filter (KF)
with nonlinear error modeling techniques such as fast orthogonal search (FOS)
was introduced t...
Evaluation of fingerprinting-based WiFi indoor localization coexisted with Bluetooth
- 2017
WiFi and Bluetooth are two most commonly used short range wireless communication
technologies. Recent years, with increasing number of WiFi and Bluetooth mobile
terminals, tags, and other devices, a demand for integration and coexistence of
these two technologies including their positioning function is booming. In this
paper, we firstly investigate the interferences between WiFi and Bluetooth
sign...
A new approach for cycle slip detection and fix using single GPS receiver’s single satellite dual frequency data containing arbitrarily large pseudorange errors
Tập 16 - Trang 1-21 - 2018
This paper presents a new cycle slip detection and repair method using Total
Electron Content Rate (TECR) information derived from individual satellite
dual-frequency data of a single Global Positioning System (GPS) receiver while
pseudorange measurements are subject to arbitrarily large range errors. Sudden
Increase of Pseudorange Error (SIPE), similar to cycle slips in nature, is quite
common in...
Adaptive cubature Kalman filter based on the variance-covariance components estimation
Tập 15 - Trang 1-9 - 2017
Although the Kalman filter (KF) is widely used in practice, its estimated
results are optimal only when the system model is linear and the noise
characteristics of the system are already exactly known. However, it is
extremely difficult to satisfy such requirement since the uncertainty caused by
the inertial instrument and the external environment, for instance, in the aided
inertial navigation. I...
Camera auto-calibration in GPS/INS/stereo camera integrated kinematic positioning and navigation system
Tập 14 - Trang 1-15 - 2016
This paper presents a novel two-step camera calibration method in a
GPS/INS/Stereo Camera multi-sensor kinematic positioning and navigation system.
A camera auto-calibration is first performed to obtain for lens distortion
parameters, up-to-scale baseline length and the relative orientation between the
stereo cameras. Then, the system calibration is introduced to recover the camera
lever-arms, and...
Development of a GPS spoofing apparatus to attack a DJI Matrice 100 Quadcopter
Tập 16 - Trang 1-11 - 2018
Global Positioning System (GPS) Spoofing attacks threaten technologies that our
modern society depends on. To successfully develop defensive mechanisms against
these attacks, methods to model the attacks and subsequently distinguish them
from normal GPS operation must be developed. This paper primarily details the
step-by-step implementation of a low-cost GPS spoofing and high-level spoofing
data ...
Review of triple-frequency GNSS: ambiguity resolution, benefits and challenges
Tập 16 - Trang 1-11 - 2018
Triple-frequency GNSS has been intensively studying in the past decades,
especially with the open service of China’s BeiDou system. In this review, we
will address the ambiguity resolution, benefits gained from additional frequency
signals compared to the dual-frequency GNSS signals, as well as analyse the
challenges of triple-frequency GNSS for future development. We first review and
compare the ...
Accuracy analysis of GPS/BDS relative positioning using zero-baseline measurements
Tập 16 - Trang 1-8 - 2018
This paper focuses on assessing the precision of carrier phase relative
positioning using GPS-only, BDS-only and GPS/BDS measurements. A zero baseline
is used in order to achieve this. Software for GPS and BDS processing has been
developed, allowing static and kinematic data processing, as well as the
combined GPS and BDS processing. Ionospheric and tropospheric delays are
significantly reduced by...
An assessment of the interoperability of PPP-AR network products
Tập 15 - Trang 1-12 - 2017
Integer ambiguity resolution of carrier-phase measurements from a single
receiver can be implemented by applying additional satellite corrections
(products) to mitigate unmodelled satellite equipment delays. Interoperability
of different PPP-AR products would allow the PPP user to transform independently
generated PPP-AR products to obtain multiple fixed solutions of comparable
precision and accur...
