121.5MHz frequency achieves double-digit year-over-year growth with autopilot
The "off-season is not short" of new energy vehicles is the result of various efforts, which also highlights the future development trend of new energy.
At present, the demand for stable growth in China is becoming more and more obvious. Under the strategic requirements of expanding domestic demand, automobile consumption is expected to become an important force, and the necessity of stabilizing automobile consumption is increasing. Next, we need to further strengthen scientific and technological research, break through the development bottlenecks of new energy vehicles such as battery life and chips, and help achieve high-quality development of my country's automobile industry.
If you seize the core chip, you will seize the core of the smart car industry chain. Driven by the development trend of automobile electrification, intelligence, and networking, the global automotive chip has ushered in a period of rapid development.
According to IDC data, in 2024, the global L1-L5 autonomous vehicles (autonomous vehicles are divided into five levels according to the level of automation, respectively: L1 level partial driving assistance, L2 level combined driving assistance, L3 level conditional autonomous driving , L4 level highly autonomous driving, L5 level fully autonomous driving) shipments are expected to reach about 54.25 million units, with a compound annual growth rate (CAGR) of 18.3% from 2020 to 2024.
The technological progress of automotive chips depends on the development of the semiconductor market. IDC expects that the application of semiconductors in the field of automotive chips will maintain rapid growth in the next five years.
From 2022 to 2024, the global automotive semiconductor market will achieve double-digit year-on-year growth.
The position indicator is generally composed of a protective cover, a latch, a hydrostatic pressure releaser, a 406MHz transmitter, a 121.5MHz transmitter, a Gpp receiver, an antenna, a short buoyancy cable, a battery, a water-sensitive electrode, a magnetic switch, and a control switch. Among them, the 406MHz frequency band uses the COSPAS-SARSAT satellite to locate and identify signals, and the 121.5MHz frequency helps search and rescue through automatic guidance.
There are two ways to transmit the position indicator: one is to manually start the launch. When the ship is in distress, the crew takes the position indicator out of the protective cover, actively turns on the control switch, and transmits the signal; the other is to automatically launch, when the ship goes down. When the position indicator sinks into the water for 1-3 times, the hydrostatic pressure releaser will act to cut off the plastic bolts, the position indicator will float away from the protective cover, the magnetic suction switch and the water sensitive electrode will be turned on at the same time, and an alarm will be automatically issued.
