Firefly SageSON-I UAV Self-organized Network

SageSON-i Self-organized network is a product developed by our company for the application of UAV air self-organized network.
SageSON-i Self-organized Network can form a self-organizing network among nodes. It can be used in formation of aircraft and can communicate with ground or water.
SageSON-i Self-organized Network has been identified by user organizations.
SageSON-i self-organized network has a serial port (RS232/422), which supports air speed up to 230.4 Kbps. It can be used for data sharing among all nodes in the network, such as remote control commands, Beidou/GPS position, flight status, sensor data and so on.
SageSON-i self-organized network has good scalability and self-healing. Damage, joining and quitting of any node will not affect the normal operation of the network.
SageSON-i self-organized network is characterized by short delay and synchronization , and has significant advantages in the application of real-time control in formation.
SageSON-i is small in size, light in weight, low in power consumption, low in delay and transmission delay as low as 20 milliseconds. Under the condition of aerial vision, the single hop communication distance between nodes can reach 50 kilometers.
The network has strong self-sustainability and does not need external clock source to provide time. This characteristic has high practical value.
II、Features
- Short delay: End-to-end delay of data transmission between any two nodes is not more than 20 milliseconds
- Strong survivability: nodes can join and exit freely
- Self-healing: reconstruction time is about 100 milliseconds to 1 second
- High Speed: Wireless Air Speed up to 230.4 kbps (customizable products up to 1 Mbps)
- The number of nodes in the network does not affect the transmission rate of each node
- Without external clock source timing, even if GPS and Beidou are disturbed, the radio can still synchronize.
- Network capacity: In theory, it can accommodate thousands of nodes: at present, the maximum number of nodes is not less than 120;
- Stable Communication (Anti-Doppler Frequency Shift) for High Speed Motion of Carrier
- The visual distance is not less than 50 kilometers. Accept customization more distantly
