Frequency ranges used by unmanned aircraft systems include 840.5-845MHz, 1430-1444MHz and 2408-2440MHz. The specific usage is as follows:

1. 840.5-845MHz: This frequency band is used for the uplink remote control link of unmanned aircraft systems. Among them, 841-845MHz can also be used for the uplink remote control and downlink telemetry links of unmanned aircraft systems.

In addition, civilian drones can apply to use the 840.5-845MHz, 1430-1444MHz, 2400-2476MHz (hereinafter referred to as 2.4GHz), 5725-5829MHz (hereinafter referred to as 5.8GHz) frequency bands for remote control, telemetry, and information transmission links. At present, the distribution of UAV operating frequency bands is mainly concentrated in the following frequency bands:              signal jammer

1. 2.4GHz and 5.8GHz: These two frequency bands are frequency ranges widely used by civilian drones for remote control, telemetry and information transmission links.

2. 840.5-845MHz: This frequency band is mainly used for the uplink remote control link of the unmanned aircraft system. Some of the frequency bands can also be used for the uplink remote control and downlink telemetry links of the unmanned aircraft system.

3. 1430-1444MHz: This frequency band is mainly used for downlink telemetry and information transmission links of unmanned aircraft systems. Some of the frequency bands are used for video transmission of police unmanned aircraft and helicopters.

The 5.2GHz drone mainly has the following functions:
1. Real-time image transmission: 5.2GHz drones can transmit high-quality images and videos in real time, and the effective distance is usually between 1 km and 2 km, or even further.
2. Positioning: Using the GPS and Beidou dual-mode positioning systems, the 5.2GHz drone can obtain correct positioning information.
3. High-speed data transmission: 5.2GHz drones can be used for high-speed data transmission, such as playing an important role in emergency rescue, material transportation and other fields.
4. Remote control: Through the 5.2GHz remote control, users can operate the drone from a long distance to perform various tasks.
5. High-definition video recording: Some 5.2GHz drones also have high-definition video recording functions, which can shoot clear and stable videos.
6. Various mission loads: According to different mission requirements, 5.2GHz UAVs can be equipped with different mission loads, such as infrared payloads, laser payloads, etc.
7. Intelligent flight: Using advanced algorithms and sensor technology, 5.2GHz drones can fly intelligently, automatically track targets, plan routes, etc.
8. Real-time image and video transmission to the remote control: This function allows users to view the drone’s shooting footage or detection data in real time on the remote control to understand the drone’s working status and environmental conditions.
