The Federal Aviation Administration (FAA) Technical Center conducted this test project under Technical Program Document (TPO) 04-150 to determine the operational suitability of the Navigation Satellite Timing and Ranging Global Positioning System (NAVSTAR GPS) for rotary wing aircraft. The flight tests were conducted in a CH-53A helicopter using a

The intent of this document is to provide a functional description of the serial data reformatter equipment, and to enumerate it's capabilities and uses.
Expressions for Global Positioning System (GPS) user errors in pos1t1on and time are derived for the situation of the receiver utilizing data either from four satellites or from three satellites plus an altimeter. The derivation assumes that the satellite pseudo-range/altimeter measurement errors are independent, but not necessarily equal. The pred

This report documents the programs which compute and plot the GPS user errors from pseudo-range errors (biases and standard deviations which are independent but not necessarily equal) on the HP 1000 for different satellite/configurations with and without an altimeter input.
As part of an overall effort to determine the operational capabilities of LORAN-e navigation in the civil aviation environment, this test plan specifically addresses Power Line carrier (PLC) interference and its effect on LORAN-C avionics performance.
The purpose of this project is to determine if wind shear phenomena can be reliably detected and measured with the ASR-8 pulse Doppler system employing a continuous antenna scan.
The purpose of this project is to quantify any Airport Surveillance Radar (ASR) Moving Target Indicator (MTI) enhancer signal processing losses and target azimuth shifts resulting from adjustment of the MTI enhancer parameters to provide optimal non-synchronous interference rejection.
This report documents the measured position accuracy of a portable tracking system and the details of the post flight data computations. The system was assembled by personnel at the FAA Technical Center using a combination of off-the-shelf hardware and in-house designed hardware and software. The system will be used to provide an accurate position

This report documents the FORTRAN program ANTHTSl. The program will accept input values for the ILS glide slope null reference, sideband reference, or capture effect antenna systems. The program then uses these values to calculate other unknown factors about the system.

This video describes the five components of intelligent vehicle highway systems (ATMS, ATIS, APTS, CVO, AVCS). By utilizing advanced technologies in the computer, control and communications fields, IVHS has the potential to ameliorate traffic congestion and improve traffic safety on the nation's highways.

Anti-icing is a systematic approach to winter road maintenance. It requires the use of the right tools (material, equipment, personnel and strategy) in the right place and at the right time to prevent or reduce the ice-pavement bond.
Tells pavement designers how springy the subgrade material is under stress-- how much it deforms under a known load and also how much it springs back. Resilient modulus is a way of characterizing the stiffness of the material.
The New Mexico Department of Transportation re-opened its library in 2025 after being closed for several years. Speaker and solo librarian Amy Boggess shares an overview of the Research and Climate Bureau building that houses the library, the history and timeline of the library’s closing and re-opening, and progress made in establishing the new era
