The document discusses inertial navigation systems (INS) and their use in dynamic positioning (DP) applications. An INS uses gyroscopes and accelerometers to continuously calculate position without external references. While INS drift over time, integrating additional sensors like acoustic positioning, Doppler velocity logs, and GPS can significantly improve accuracy through data fusion. The document examines how pairing an INS with acoustic positioning systems can provide reliable, high-accuracy positioning even if individual sensors fail or are unavailable. It suggests INS combined with acoustic loggers is sufficient redundancy and accuracy for many DP applications.
This document analyzes the performance of GLONASS-only and BeiDou-only real-time kinematic (RTK) positioning using Leica Viva GNSS receivers. It assesses the availability, accuracy, reliability, and time to fix of GLONASS-only and BeiDou-only solutions in comparison to GPS-only and combined GNSS solutions. The document presents results from both canopy and open-sky data collections in Shanghai, China. It finds that while BeiDou-only positioning has poorer satellite geometry and signal strength in canopy environments compared to GPS and GLONASS, the performance improves significantly in open-sky conditions as more BeiDou satellite types are available
The GEORA GNSS is a high-performance RTK receiver that supports all possible satellite constellations on all available GNSS frequencies.
It provides full support for all major satellite systems, including GPS, GLONASS, GALILEO, BDS, QZSS, and SBAS, making it an ideal tool for various geodetic and GIS applications.
The GEORA GNSS receiver is equipped with a new
generation IMU sensor, which features rapid initialization
and increased resistance to electromagnetic interference. The new IMU sensor does not require calibration, making its use even more convenient and efficient.
Thanks to the built-in IMU, the GEORA GNSS receiver allows for high-precision measurements without the need to level the receiver. The sensor operates at a frequency of up to 200 Hz, ensuring exceptional accuracy and response speed.
The GEORA GNSS features improved tilt compensation
technology. With the IMU activated, the horizontal
measurement accuracy is 1.5 cm at a tilt of up to 60 degrees, and at a tilt of up to 90 degrees, the horizontal accuracy reaches 2 cm. This allows users to perform
precise measurements even in challenging conditions when the device is tilted or moving.
Using the GEORA GNSS receiver with integrated IMU provides a new experience in using GNSS RTK
technologies, combining high accuracy, speed, and ease of use.
The Trimble R10 GNSS system provides several advanced features for precise positioning including Trimble HD-GNSS for more accurate measurements, Trimble SurePoint for faster measurements and tilt compensation, Trimble xFill which allows continuous surveying when disconnected from a base station using satellite corrections, and Trimble 360 which supports multiple satellite constellations. It has an ergonomic design that is rugged, compact, and lightweight. When used with Trimble Access and Business Center software it provides a complete surveying solution.

This document summarizes inertial navigation systems and motion sensing products from SBG Systems, including their Apogee and Ekinox series. It provides specifications for accuracy, interfaces, environmental tolerances, and positioning capabilities for their MEMS-based inertial measurement units, attitude and heading reference systems, motion reference units, and inertial navigation systems. Their products are designed for applications in aerospace, ground, marine, and tactical domains.
Advanced driver assistance systems (ADAS) are a key technology for improving road safety. But both current and proposed ADAS are limited in important ways. Vision- and lidar-based ADAS performs poorly in heavy rain, snow, or fog. Lack of vehicle situational awareness due to these sensing limitations will unfortunately be the cause of many accidents, including fatalities, for connected and automated vehicles in the years to come. The goal of this research is to develop and test a sensing strategy with robust perception: No blind spots, applicable to all driveable environments, and available in all weather conditions. We believe there are three key requirements for collaborative all-weather sensing:
– Precise vehicle positioning within a common reference frame
– Decimeter-accurate vision and radar mapping
– A means of quantifying the benefits of collaborative sensing

A Review on Airlight Estimation Haze Removal AlgorithmsIRJET Journal
This document reviews algorithms for estimating airlight to remove haze from images. It discusses how haze degrades image quality by attenuating light reflected from objects and adding atmospheric light. Common haze removal techniques rely on a atmospheric scattering model. The dark channel prior method estimates atmospheric light using the fact that at least one color channel will have some pixels with very low intensities in haze-free images. Bilateral, trilateral, and CLAHE filters can then be used as post-processing steps to improve results. The document aims to develop new airlight estimation methods with lower computational complexity.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Floodlight Shadow Reduction
What is Satellite Shadow?
Satellite shadow occurs when
an obstacle between a GNSS
satellite and a receiver stops
the receiver from tracking the
satellite effectively.
As more satellites are blocked
from view, it becomes
progressively more difficult for
the receiver to compute
accurate positions. In extreme
cases there are simply too few
satellites in view to compute
positions at all.
3. Trimble Technologies
Floodlight
How Does Floodlight Technology Mitigate Satellite Shadow?
• By combining GPS and GLONASS tracking, satellite availability is
increased by up to 60% over GPS-only positioning.
• Advanced tracking algorithms speed up signal acquisition and
ensure more stable tracking of satellites with weakened signals.
With steadier tracking comes smoother positioning that is less
prone to drop-outs and spikes caused by erratic satellite tracking.
• Floodlight technology uses altitude-constrained positioning to
reduce the impact of weakened or blocked signals. This technique
limits the impact of weak signals, allows 3D positioning with fewer
satellites, and improves horizontal and vertical accuracy.
Floodlight technology is compatible with real time and postprocessed
workflows. There is no extra configuration, back-office processing, or
quality control required—it just works.

With

Through advanced algorithms, it chooses the picks the only the satellites
that fall within the horizontal range.
6. Trimble Technologies
Floodlight
Why is Floodlight Technology Better Than Other
Techniques To Improve Position Availability?
Receivers that address satellite shadow by offering
GPS and GLONASS positioning are only solving part of
the problem.
Other solutions that use lower quality thresholds may
increase position yield in obstructed conditions, but
do so at the expense of accuracy. Floodlight
technology tackles satellite shadow by improving
satellite visibility and tracking while safeguarding
against the effects of weak satellite signals on position
quality— achieving the best possible position.
