![]() ![]() ![]() The satellites calculate the position or utilize the GPS coordinates of the beacon and quickly passes the information to the appropriate local first responder organization, which performs the search and rescue. The signal is detected by satellites operated by an international consortium of rescue services, COSPAS-SARSAT, which can detect emergency beacons anywhere on Earth transmitting on the distress frequency of 406 MHz. In the event of an emergency, such as a ship sinking or medical emergency onboard, the transmitter is activated and begins transmitting a continuous 406 MHz distress radio signal, which is used by search-and-rescue teams to quickly locate the emergency and render aid. First generation EPIRB emergency locator beaconsĪn emergency position-indicating radiobeacon ( EPIRB) is a type of emergency locator beacon for commercial and recreational boats, a portable, battery-powered radio transmitter used in emergencies to locate boaters in distress and in need of immediate rescue. Overview diagram of COSPAS-SARSAT communication system used to detect and locate ELTs, EPIRBs, and PLBs. The RQ-20B can be provided with smart battery options for increased mission capability.For broader coverage of this topic, see Emergency locator beacon. It can fly at 500ft altitude and offers a flight time of more than three hours. The drone has the ability to travel at speeds between 20k and 45k and transmit telemetry data over a range of 15km. The propulsion system comprises a long-endurance battery, driving a two-blade propeller mounted in tractor configuration. The RQ-20B UAV features an enhanced propulsion system that allows for operation at higher altitudes in difficult climatic conditions. ![]() Propulsion and performance of RQ-20B Puma AE UAS The operation and control of the RQ-20B Puma AE UAS is performed from the launch ship’s command and control system.Ī secure digital data link developed by AeroVironment transmits the real-time ISRT data collected by the UAV to the command and control server, as well as to the operator’s communications network. The Mantis i45 sensor suite offers high-resolution imagery and video, as well as tactical ISR capability. The UAS is compatible with Mantis i45 EO / IR gimbal payload developed by AeroVironment. It can carry additional payloads, such as a laser marking system, communications relay and geolocation sensor, in an optional under-wing Transit Bay. The camera system provides target location, ISRT data, and digital high-definition imagery and video in both day and night lighting conditions. The block 2 Puma AE drone carries an electro-optical / infrared (EO / IR) camera system and illuminator in a lightweight, mechanically-stabilised gimbal payload pod fitted beneath the fuselage. The drone can also be recovered using the deep-stall landing method. It can operate autonomously through predefined way points, using a GPS-based precision inertial navigation system.Ī precision recovery system built by AeroVironment enables the UAV to automatically land into a net on the flight deck of the launch vessel. It is able to be launched quickly, either by hand or rail launch method, from a range of naval vessels. ![]()
