This document discusses the tradeoff between privacy and GPS integrity. It acknowledges graduate students and researchers who contributed to spoofing GPS signals experiments. It shows graphs depicting meters of error over time from spoofing tests. It proposes that spoofing could be used to create a "virtual tractor beam" to control a target drone by transmitting spoofed GPS signals that manipulate its reported coordinates based on its location from a tracking system.

Laser communications could improve unmanned aerial vehicle (UAV) operations by providing faster transmission speeds and higher bandwidth than traditional radio waves. The document proposes a research design to test laser communication links between a UAV and ground control station, and between the ground control and a test satellite. If successful, the tests would establish that laser communications can enhance UAV data transmission by offering line-of-sight transmission without bandwidth limitations.
GPS
The GPS system uses 24 satellites and ground control stations to provide location data to users worldwide. It determines a user's position by precisely measuring travel times of radio signals between the user's receiver and multiple satellites. At least 4 satellites are needed to calculate the user's 3D position and the receiver's internal clock offset. The system provides critical navigation for military, civil and commercial applications on land, sea and air.
GPS and GIS
This document discusses geographic information systems (GIS) and global positioning systems (GPS). GIS puts important location-based information like states, roads, and city boundaries onto maps. GPS uses satellites to provide precise location coordinates, with most consumer GPS having an accuracy of around 10 meters. The document outlines how surveyors will use GPS-enabled devices and trackers to obtain multiple location readings for assets, which will then be averaged and mapped as a GIS layer to mark the fixed positions of sites on a map.
Satellite communication Basics
This document provides an overview of satellite communication and satellite systems. It discusses different types of transmission systems including radio, coaxial cable, and optical fiber systems. It describes how radio systems use electromagnetic waves to transmit signals and the portions of the frequency spectrum used. The document outlines the layers of the atmosphere and how the ionosphere and troposphere can propagate radio waves. It also categorizes different types of radio communication including ionosphere communication, line of sight microwave communication, and troposphere scatter communication. The document discusses advantages of satellite communication and components of a satellite communication network including the space and ground segments. It covers topics like satellite orbits, frequency bands used, and multiple access techniques in satellite systems.
Communication in space
The act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules.
Indian remote sensing satellite,potentials with a revolution
Indian Remote Sensing satellites provide remote sensing services to India. Data from these satellites are used for various applications like crop production estimation, drought monitoring, land use mapping, and more. The Cartosat-1 satellite has panchromatic cameras with a spatial resolution of 2.5 meters. It collects data that is processed and analyzed to derive information about vegetation, water bodies, and other landscape features with various applications such as malaria risk mapping. Remote sensing technologies allow analyzing large regions from space and measuring energy beyond human vision to enable global monitoring.

Historical aerial scanning project
This document summarizes a project by the Texas Water Development Board and TNRIS interns to digitize and georeference historical coastal aerial photographs from 1940-1990. The interns will scan over 5,000 photos per month to preserve them and prevent damage. The georeferenced scans will be made available online. The process involves scanning, georeferencing, mosaicking and enhancing the images. Stakeholders benefit from preserved history and access to coastal change data. Interns gain experience that improves employment prospects.

Building a water resources geodatabase for the rio grande basinTexas Natural Resources Information System
This document discusses the creation of a geodatabase to organize water resources data from multiple sources for the Rio Grande Basin from New Mexico to Texas. Data from various agencies over decades was compiled and preprocessed using scripts to ensure data integrity and consistency. The geodatabase facilitates identifying data gaps and supports spatial analysis to assist decision making. Organizing diverse data from many sources into a single, well-documented geodatabase enhances usability and the ability to conduct hydrologic studies.Txgio presentation rgsm_gps_pearson_062012
This document summarizes a project that mapped riverine habitat in the Rio Grande to support the experimental reintroduction of the endangered Rio Grande silvery minnow. Researchers used high-precision GPS to map habitat types at different river flows. They collected data on physical characteristics and fish assemblages. The resulting spatial database will help understand habitat variability and fish distributions to aid conservation of the silvery minnow.

Using gps technology at the texas general land
The Texas General Land Office uses GPS technology to help manage natural resources on state lands and ensure compliance with oil and gas leases. GPS is used to map oil and gas wells, pipeline easements, coastal wildlife habitats, structures permitted on public lands, and areas for brush control. Data collected through GPS devices is uploaded to the GLO's GIS system to help visualize management alternatives and support activities like oil spill response planning. The GLO utilizes various GPS units including Delorme and Leica devices.

Adani SEBI investigation revealed that the latter had sought information from five foreign jurisdictions concerning the holdings of the firm’s foreign portfolio investors (FPIs) in relation to the alleged violations of the MPS Regulations. Nevertheless, the economic interest of the twelve FPIs based in tax haven jurisdictions still needs to be determined. The Adani Group firms classed these FPIs as public shareholders. According to Hindenburg, FPIs were used to get around regulatory standards.
