According to CCTV news, at 4:50 am on September 29, the domestic Pterosaur-2 UAV took off from Guizhou Anshun Airport and rushed to Muli, Sichuan, where it successfully carried out the world's first large-scale UAV emergency communication exercise.
This emergency communication exercise was jointly implemented by China Aviation Industry Corporation, China Mobile, China Electric Power and other units, using the domestic Pterosaur-2 large UAV to build a "space, space and earth" in areas without signal coverage through satellite links. Integrated emergency communication platform.
This emergency communications exercise was conducted in Muli, Sichuan, where there is high mountains and dense forests and no public network coverage, in order to simulate a major disaster in this area, drones to provide communication support for rescue teams.
It is reported that in the test area, the Pterosaur-2 UAV carried out hovering flights at different altitudes, and carried out emergency communication guarantee tests in three frequency bands: public network, private network and ultrashort wave. The test results show that the Yilong-2 UAV has a clear return image, and the live audio and video data is cross-linked with the emergency management department command hall in real time, realizing real-time dispatch and efficient command.
This actual combat exercise realized for the first time cross-airspace, cross-day and night, emergency communications in actual combat scenarios. Nearly 20 hours of continuous flight verified the high reliability of the Pterosaur-2 UAV and its excellent adaptability to complex environments.

CTCSS function on walkie-talkies covers a frequency range from 67.0Hz to 250.3Hz. When transmitting in analog sub-tone mode, it transmits by continuously superimposing low-frequency, inaudible signals onto the carrier frequency, ensuring that only receivers receiving the same frequency can interpret the signal. This achieves anti-interference capabilities or allows the receiver to reject signals from other third parties.
