Characteristics and Capabilities of Rescue Satellites 5

What is a rescue satellite The satellite search and rescue satellite system uses a satellite system to determine the distress signals sent from the sea, air and ground distress devices, so as to determine the location of the danger and implement the search and rescue system. The system mainly consists of satellites, ground segments, and beacon machines. The Beacon in distress emits distress satellites with frequencies of MHz and 406MHz.

Alarm signal, the satellite receives and demodulates the alarm signal, completes the Doppler frequency shift measurement, and then sends the relevant data information back to the ground with 1 MHz. The ground segment includes a ground terminal, a control center, and a search and rescue center. The satellite has an altitude of 850 1 000 km and takes about 100 minutes to orbit the Earth.

The Doppler frequency shift generated by the relative motion between the satellite and the beacon can be processed to obtain the position of the beacon machine. The positioning error of the frequency indicator beacon is about 17 km, and the positioning error of the frequency 406MHz positioning beacon is about 5 km.

Rescue, or what is it called a rescue satellite?

A distress signal was heard from the ship.

Hearing the distress signal from the ship or aircraft, quickly and accurately determine the location, and report to the ground rescue center urgently. After the rescue center got the information, it immediately sent *** to the place of distress so that the victims could be saved.

A rescue satellite is a type of artificial satellite used to rescue wrecked planes and ships.

Rescue satellites are used to measure distress signals from distress devices at sea, in the air, and on the ground, so as to determine the location of distress, and carry out search and rescue.

The rescue process is mainly composed of satellites, ground segments and beacon machines. The distressed beacon sends out distress warning signals with frequencies of MHz and 406MHz, and the satellite receives and demodulates the warning signal, completes the Doppler shift measurement, and sends the relevant data information back to the ground at 1 MHz. The ground segment includes a ground terminal, a control center, and a search and rescue center.

The role of rescue satellites is to use satellite systems to measure distress signals sent from distress devices at sea, in the air, and on the ground, so as to determine the location of distress and carry out search and rescue.

The rescue satellite system is mainly composed of satellites, ground segments and beacon machines. The distressed beacon sends out distress warning signals with frequencies of MHz and 406MHz, and the satellite receives and demodulates the alarm signal, completes the Doppler shift measurement, and then sends the relevant data information back to the ground in MHz.

Specialized rescue can be accurately located.

The rescue satellite is to use the satellite macro sensitive system to measure the distress signal sent from the sea, air and ground distress devices, so as to determine the location of the distress and carry out search and rescue. The rescue satellite mainly consists of a satellite, a ground segment and a beacon machine.

The technology of using artificial satellites to search and rescue wrecked planes and ships is to receive the signals of the emergency beacon loaded on the wrecked planes and ships by satellite radio and send them to the ground information receiving station, and the receiving station notifies the rescue command center for rescue.

Rescue satellites usually use satellites operating in near-circular polar orbits at an altitude of 850 1000 kilometers to carry rescue signals, and the ground receiving station determines the location of the crash site according to the principle of Doppler frequency shift of radio signals caused by the relative movement between the emergency beacon and the satellite.
