What is Automatic Direction Finder?

Automatic direction finding is a marine or aircraft radio-navigation instrument that identifies the relative bearing of an aircraft to the suitable radio station by using the radio signals in the low to medium frequency band of 190 Khz. to 1750 Khz. for navigation purposes. The ADF receives radio signals with the help of two antennas, first is a loop antenna which determines the strength of the signal which it receives from the ground station to determine the direction of the station. The second is the sense antenna which determines whether the aircraft is moving toward or away from the station. A pointer indicates the relative bearing to the station. and when the indication is 0°, the aircraft is on course to (or from) the station.

The Automatic direction finding is used in the aircraft by pilots to determine the position of NDB station by identifying the appropriate frequency for the NDB station on the ADF selector through a fixed-card bearing indicator with an arrow that points in the direction of the beacon. The various type of ADF is maritime, mobile land and airborne which are used for application in air traffic control, vessel traffic service, search and rescue, others.

The major production of automatic direction finder is in the region such as United States, Germany and Japan with the high demand of the ADF in North America.

Reconstructing past landscapes from historical maps requires quantifying the accuracy and completeness of these sources. The accuracy and completeness of two historical maps of the same period covering the same area in Israel were examined: the 1:63,360 British Palestine Exploration Fund map (1871-1877) and the 1:100,000 French Levés en Galilée (LG) map (1870). These maps cover the mountainous area of the Galilee (northern Israel), a region with significant natural and topographical diversity, and a long history of human presence. Land-cover features from both maps, as well as the contours drawn on the LG map, were digitized. The overall correspondence between land-cover features shown on both maps was 59% and we found that the geo-referencing method employed (transformation type and source of control points) did not significantly affect these correspondence measures. Both maps show that in the 1870s, 35% of the Galilee was covered by Mediterranean maquis, with less than 8% of the area used for permanent agricultural cropland (e.g., plantations). This article presents how the reliability of the maps was assessed by using two spatial historical sources, and how land-cover classes that were mapped with lower certainty and completeness are identified. Some of the causes that led to observed differences between the maps, including mapping scale, time of year, and the interests of the surveyors, are also identified.

The AHF system has been deployed in a series of survey campaigns to collect over 60,000 points covering Everglades National Park, Loxahatchee National Wildlife Refuge, Water Conservation Areas 2 and 3, portions of Big Cypress National Preserve, as well as areas along the Lake Okeechobee littoral zone. Since the AHF System is able to penetrate Everglades vegetation and water cover, it has provided an unprecedented regional view of Everglades topographic gradients and sub-water surface structure. These data are now being used to simulate Everglades water flow with higher resolution and greater accuracy, to estimate water depths in real-time for field study planning, and as input for habitat models used to forecast the effects of water level changes on various important species. The elevation data collected through this project also formed the basic input to generate a regional topographic surface that is the basis for the Everglades Depth Estimation Network (EDEN). These high accuracy elevation data are made available to anyone through the South Florida Information Access website (http://sofia.usgs.gov) data exchange pages.

MAP Activity Accomplishment The USGS Airborne Height Finder (AHF) System was used to perform topographic surveys in Water Conservation Area 3A within the extents of the Lone Palm Head and North of Lone Palm Head 7.5-minute topographic map quadrangles as specified in the MAP/COE Interagency Agreement. The AHF system has been used throughout South Florida for elevation data collection because traditional surveying methods are too difficult, too costly, or simply impossible to use in the harsh wetland environment and broadly inaccessible terrain of the Florida Everglades. This is especially true considering the shear size of the hydrodynamic and biological modeling domains. The AHF is a helicopter-based instrument that uses a GPS receiver, a computer, and a mechanized plumb bob to make measurements. These data were post processed to the reference stations that are part of the AHF geodetic control network. For reasons of accuracy, these reference stations are located no more then 15 kilometers from the helicopter during AHF operations. The GPS data were post processed using Ashtech’s PNAV On The Fly (OTF) software to obtain the trajectory of the AHF platform. These results are then processed through an in-house software package that separates the actual survey points and results from the trajectory. The points are manually checked to ensure data accuracy and completeness. Digital elevation models (DEMs) were then generated from the elevation point data. Existing elevation data derived from LiDAR data for this area were replaced with AHF derived DEMs for reasons of vertical accuracy. The DEMs have been posted on the South Florida Information Access (SOFIA) website: http://sofia.usgs.gov/exchange/desmond/desmondelev.html.

Search and Rescue Satellite Aided Tracking (SARSAT)A Beacon of Hope to Those in DistressNOAA satellites do more than just monitor the weather. They also detect and relay distress signals from emergency beacons to the appropriate search and rescue authorities. This tells them who is in trouble and, more importantly, where they are located.The NOAA–SARSAT program is part of COSPAS–SARSAT, an international satellite-based monitoring initiative to which 45 nations and independent search and rescue organizations belong. Using this system, authorities can locate beacons almost anywhere in the world at any time, and in almost any condition. COSPAS stands for "COsmicheskaya Sisteyama Poiska Avariynich Sudov," Russian for “Space System for the Search of Vessels in Distress.” A sailor being rescued at sea.SARSAT Tracking ApplicationEach icon on this map represents one rescue event within the U.S. Area of Responsibility (AOR) in 2016, though multiple saves may be involved with each event. The Search and Rescue Satellite Aided Tracking (SARSAT) system is able to detect three types of beacons: an individual’s Personal Locator Beacons (PLBs), maritime Emergency Position Indicating Radio Beacons (EPIRBs), and aircraft Emergency Locator Transmitters (ELTs). Who responds to the search and rescue are dictated by the location of the distress. For any beacon activation that occurs in the U.S. AOR, the U.S. is responsible for responding. If it is inland, U.S. Air Force responds*, if it is at sea, the U.S. Coast Guard. If a device registered to another country is activated within the U.S. AOR, the U.S. is still responsible for the rescue but their homeport country will be notified of the event. All areas of the world are covered by COSPAS-SARSAT.The COSPAS–SARSAT ProgramThis program consists of: Emergency beacons that transmit distress signalsSatellites that detect the distress signalsGround receiving stations that receive and process the satellite signals to generate distress alertsMission control centers that receive the alerts and forward them to rescue coordination centers, operated by the U.S. Coast Guard and the U.S. Air Force.The U.S. SARSAT system uses NOAA satellites in low-earth and geostationary orbits as well as GPS satellites in medium earth orbit to detect and locate aviators, mariners, and land-based users in distress. The satellites relay distress signals from emergency beacons to a network of ground stations and ultimately to the U.S. Mission Control Center (USMCC) in Suitland, Maryland.Types of search and rescue beacons. The Four Agencies Involved in the U.S. SARSAT ProgramNOAA: System Operation and representative to COSPAS-SARSATNASA: Research and Development U.S. Coast Guard: Maritime Search and Rescue U.S. Air Force: Inland Search and Rescue HistoryCredit: Arizona Daily StarThe first beacons used the existing 121.5/243 MHz emergency locator transmitters (ELTs) designed for military aircraft in the 1950s. After a small plane carrying Rep. Hale Boggs (D-La.) along with Rep. Nick Begich (D-Alaska) and others disappeared in Alaska in 1972, Congress mandated ELTs on all U.S. aircraft. Canada soon did the same. However, early models were not as easy to detect, and there was no way to identify a specific beacon or find its exact location. Thus, engineers began developing new, more robust digital beacons that operated at 406 MHz. Signals from these new beacons could be received from anywhere on the planet, located accurately and almost instantly, and rescue forces would know who and what to look for.The United States and Canada began looking for other international partners with the ability to launch satellites to achieve a truly global distress alerting satellite system. Russia and France soon signed on to help develop the system for humanitarian purposes. On June 30, 1982, Russia launched the first experimental COSPAS–SARSAT satellite. Before it was even officially declared operational, the first distress signal was detected—a downed Canadian aircraft. Within the first hundred days of the satellite’s operation, seven people were rescued using the system. Soon after, NASA launched their own SARSAT payload on NOAA-8. The program has continued to grow ever since. Today, with newer, more advanced beacons and a global network of next generation satellites, COSPAS–SARSAT strives to keep improving its ability to take the “search” out of “search and rescue” and ultimately save lives.
