Next generation GPS satellite aided Distress Alerting system becomes an integral part of Worldwide Search and Rescue operations

by Russel 2012-01-13 13:03

Satellite-Aided Search and Rescue Technology for detection and location of aircraft and vessels in distress which was originally developed by NASA has evolved into an international cooperative project to fulfill Search and Rescue objectives by enhancing the global Cospas-Sarsat system with improved space-based distress alerting and locating capability. NASA leads research and development or application of advanced technology to develop highly efficient search and rescue, survival and recovery systems. They include GPS navigation and tracking solutions, transmitters, receivers, and antennas capable of locating spacecraft, aircraft, ships, vehicles and individuals in potential or actual distress. The Satellite Aided Search and Rescue System serves search and rescue agencies worldwide with a network of 58 ground terminals. It currently has 38 participating countries, with Cospas-Sarsat payloads on 11 satellites, orbital spacecraft, instrumentation and equipment provided and supported by Unites States, Canada, France, and Russia. Geostationary orbit satellites have been used as key system components to detect and locate radio beacons activated by mariners, aviators and travelers in distress virtually anywhere in the world and at any time. Thousands of lives have been saved worldwide since the search and rescue satellite-aided tracking, the SARSAT system was implemented. Geostationary orbit satellites have a large field of view, although missing parts of the Arctic and Antarctic, but they cannot position a beacon unless its signal contains location information provided by an integral satellite navigation receiver. An extended study determined that a better SARSAT system would be one based on medium Earth orbit satellites. A medium Earth orbit system can provide full global coverage, determine beacon location, and do this with fewer ground stations. Global Positioning System satellites constellation provides the foundation for the improved system to help mariners, aviators, and recreational enthusiasts in distress almost anywhere in the world at anytime and in almost any condition. Included as an operational part of International Cospas-Sarsat, the Distress Alerting Satellite System is based on Global Positioning System which significantly enhances its performance. The NASA Search and Rescue Mission Office in collaboration with several government agencies including the National Oceanic and Atmospheric Administration, the U.S. Air Force and the U.S. Coast Guard has developed a next-generation satellite-aided search and rescue system, called the Distress Alerting Satellite System. The foundation of new Distress Alerting Satellite System has been established with nine GPS satellites which are hosting prototype hardware that is being used for proof-of-concept testing. The system will become fully operational after receiving complete test results that will determine the separation of search functionality out of search and rescue. The new technology will more quickly identify the locations of people in distress and reduce the risk to rescue operation teams. The SAR survival individual kit includes personal Locator Beacon and rugged waterproof GPS or floating handheld GPS navigator. The GPS satellites will have instrument clusters to relay the emergency signals from risque beacons located on the aircraft, ground vehicles, on the water vessels and in personal use. The Micro Personal Locator Beacon technology could be used as a separate tracking device or embedded in the circuitry of onboard and personal GPS navigators carried by travelers, aviators and marine enthusiasts. NASA and participating agencies are now completing the development and testing of the new system and expect to make it operational in the coming years after a complete constellation of satellites carrying the Distress Alerting Satellite System payloads is launched. Once completed the Distress Alerting Satellite System will be able to almost instantaneously detect and locate distress signals generated by emergency beacons installed on aircraft and maritime vessels or carried by travelers greatly enhancing the international community’s ability to rescue people in distress.

Aerial Sheriff surveillance drone flights provide greater safety of crime-fighting operations

by Rus Abz 2012-01-12 13:09

Adaptations of military surveillance technology are finding their way to help in everyday police operations as an efficient crime-fighting solution. The small factor unmanned aerial vehicle could be quickly deployed to track and chase down drug shipments and assess potentially precarious situations such as armed standoffs. The operating cost of the drone is tenfold lower in comparison of that required for a helicopter crew. Fully loaded the 50-pound Aerial Sheriff is compact enough to fit into the back of a truck. It can be airborne in minutes, and only takes five minutes to completely refuel. Designed to fly for extended period of time to support police surveillance operations and to get to the crime scene in no time. Equipped with night vision cameras, infrared and thermal imaging equipment the unmanned vehicle uses GPS course compass unit and GPS enabled autopilot. In fully autonomous mode the onboard flight control system relies on GPS navigator to stabilize the flight while the ground operator analyzes the real time video information. The flying sheriff captures high-resolution video and aerial photos and transmits live video stream which is secured from interception. The Aerial Sheriff is the first drone capable of carrying not only surveillance payloads like thermal imaging camera for night use, zoom lens camera and a heat seeking device, but armed weapons ranging from Tazer to small grenade launcher or a gun that fires bean bags, however there are no plans to fly weaponized police drone. A pilot on the ground is using a laptop and joystick to fly the drone by remote control. The video streaming information is used to direct officers on the ground in in the search of the suspect. Aerial Sheriff is always ready to be called to quickly get to any place miles away from the mobile host vehicle. With GPS course compass and autopilot quidance and live video stream coming from an unmanned aircraft it is a powerful tool for all kinds of police work and is always ready to be called precisely to the scene of a traffic or other accident. Law enforcement agencies are planning to use the drone helicopter to deal with criminal activities. The flying sheriff can read a license plate from 400 feet in the air and identify suspects and the vehicles that they are in. The flying sheriff could also fly to seek for missing child or the Alzheimer's patient that has wandered off and in many cases when police can take this drone and launch it and give rescue teams a greater capacity to be able to find those missing individuals. An unmanned drone uses its heat seeking camera to help a police officer track down a suspect. Equipped with powerful cameras, high precision GPS navigation and transmitting technology, the UAV can quietly hover high in the skies over any location while sending its operators real-time video of the crime scene. Police forces in the UK have been flying drones for surveillance operations for several months. In the US the drone will only be used in mission specific situations. Police departments adopting the drone technology have been working with the Federal Aviation Administration to get clearance for drone flights, come up with operator training and flight regulations for law enforcement use of unmanned aerial vehicle. As always with new technology there are concerns that application of the drone technology is moving at a faster rate than the laws. The complete number of checks and balances on the law system are currently missing. American Civil Liberties Union and civil rights monitoring organizations are working with the police and law enforcement agencies to ensure the primary use of the drone is to provide greater safety protection of SWAT teams in their legitimate police work. Flying Sheriff adds a lot of value as it discovers critical information about crime scene ahead of time for the safety of the officers. Use of the drone ensures SWAT team members are not getting hurt. Aerial Sheriff flights have demonstrated new crime-fighting technology can be utilized to provide for greater safety of SWAT teams operations.
