NASA Tests New Airborne Tracking System Designed To Bridge The Gulf

Summary:
Keeping up with aircraft flying over the Gulf of Mexico is difficult if not impossible in some instances. Now, that may change, with the help of NASA and the Department of Transportation (DOT), which are testing a new in-flight tracking system that is smaller, less costly and more flexible than anything seen to date.

Keeping up with aircraft flying over the Gulf of Mexico is difficult if not impossible in some instances. Now, that may change, with the help of NASA and the Department of Transportation (DOT), which are testing a new in-flight tracking system that is smaller, less costly and more flexible than anything seen to date.

The Advanced Air Transportation Technologies (AATT) project led by NASA's Ames Research Center, Moffett Field, CA, and the DOT's Volpe National Transportation Systems Center, Cambridge, MA, are putting the new system through its paces in Louisiana, offshore from Intercoastal City. The current testing is designed to evaluate the operational benefits of the system for fleet management in the Gulf.

The in-flight tracking system uses multiple small ground stations to triangulate on an aircraft's transponder signal, accurately determining its position. "Radar coverage, particularly at low altitudes, is non-existent over most of the Gulf of Mexico. The in-flight tracking system will provide operators with precise aircraft position data. The data from the tests will be evaluated by operators as a possible flight tracking system," said Mike Landis, AATT project manager at Ames.

The tracking system addresses many of the drawbacks of beacon radar systems currently used for air traffic control. The system's smaller size, enhanced flexibility and reduced cost permit ground stations to be placed in areas that are not feasible for beacon radar. This includes remote areas, open water and sites with mountainous terrain. These characteristics make the system particularly suitable for tracking low-flying aircraft that cannot be monitored adequately by standard radar systems.

"These tests will provide the Federal Aviation Administration (FAA) with data they can use in determining how the new system compares with radar," Landis said. "We believe the new system may have significant cost, size and flexibility advantages over currently available systems," he added.

The FAA and aviation users are evaluating the deployment of Automatic Dependent Surveillance-Broadcast (ADS-B) which is based on all aircraft transmitting their position reports (based on the Global Positioning System) to surveillance systems in the area.

The tracking system is based on equipment originally developed by the Sensis Corporation, DeWitt, NY, for the FAA's Airport Surface Detection Equipment, Mode X (ASDE-X) program. The role of the DOT is to manage deployment of the system and conduct a technical assessment for NASA.

Algonquin Power Goes Activist on Its Target Gas Natural

TheStreet (July 23, 2014) When The Deal's Amanda Levin exclusively reported that Gas Natural had been talking to potential suitors, the Ohio company responded with a flat denial, claiming its board had not talked to anyone about a possible sale. Lo and behold, Canadian utility Algonquin Power and Utilities not only had approached the company, but it did it three times. Its last offer was for $13 per share as Gas Natural's was trading at a 60-day moving average of about $12.50 per share. Now Algonquin, which has a 4.9% stake in Gas Natural, has taken its case to shareholders, calling on them to back its proposals or, possibly, a change in the target's board.
