Which system of the UAV is the data transmission in?

• Help the UAV to receive instructions from the ground station;
• Send the image information collected by the UAV payload system to the ground station;
• Transmit the UAV's attitude, position, altitude and power back to the ground station.

What is a Wireless Radio digital link

• Airborne data transmission station: connected to the UAV's autopilot through a data cable;
• Ground data transmission station: connected to the UAV ground station through data lines.

How to choose a radio data link

• ചെറിയ വലിപ്പം, ഭാരം, കുറഞ്ഞ വൈദ്യുതി ഉപഭോഗം;
• Convenient wiring and easy to use;
• Frequency hopping spread spectrum function, ശക്തമായ വിരുദ്ധ ഇടപെടൽ കഴിവ്: the higher the frequency hopping combination, the stronger the anti-interference ability. General equipment can achieve dozens or hundreds of frequency hopping combinations, and equipment with excellent performance can achieve 60,000 a frequency hopping combination.
• With store and forward function.
• With data encryption function: improve the reliability of data transmission and prevent data leakage. Common encryption methods include DES, എഇഎസ്, തുടങ്ങിയവ.
• ഉയർന്ന വേഗത: UAV data transmission radio station belongs to the category of narrow-band long-distance transmission, and the data rate of 115200bps belongs to high speed.
• With high sensitivity, കുറഞ്ഞ വൈദ്യുതി ഉപഭോഗം, ദീർഘദൂരം, high-speed frequency hopping spread spectrum, time division duplex full duplex: Since the UAV is powered by batteries, and the transmission distance is long, the power consumption of the device is required to be low (that is, low transmission power ), ഉയർന്ന വാങ്ങിക്കൊണ്ടു സംവേദനക്ഷമത (the higher the sensitivity, the farther the transmission distance). സാധാരണയായി, the receiving performance of the device is measured by the receiving sensitivity under the bit error rate, ഉദാഹരണത്തിന്: –106 dBm @ 10-6BER.
• Complete certificatioഎൻ: with CE, FCC, ETSI and other European and American mainstream certification.
