Flydragon VTOL
The Flydragon FDG23 is a Vertical Take off and Landing (VTOL) aircraft designed for aerial mapping. The Flydragon is specially designed to cover a 12 km2 area with a 90 min flight. Additionally, centimeter level positioning can be achieved after equipping with RTK. Similarly, PPK mapping also can be done. The high performance of the aircraft is due to its unique design from composite lightweight materials and low air resistance. Maximum take-off weight can reach up to and the endurance time is 160 minutes with no payload. The aircraft withstands 5.5m/s - 7.9m/s (12.5mph-17.5mph) wind. Thus, it can perform aerial missions in complex situations. The GPS module is mounted on the tail wing away from the power system, which greatly reduces interference. Further, the specifications of the Flydragon FDG23 VTOL are as follows:
Wingspan: 2300mm, Fuselage: 1200mm, Material: Composite Material, ARF Weight: 3.6kg (no battery, no payload), Max. Take-off Weight: 8kg, Suggested Max Payload: 1.5kg(excluding battery), Endurance: 160 min (1x 6S 30000mAh no payload), 120 min(1x 6S 30000mAh 500g payload), Recommended Cruising Speed: 18-20m/s, Stall Speed: 12-14m/s, Suggested Take-off Altitude: 0~3000m, Wind Resistance: 5.5 m/s-7.9 m/s (12.5mph-17.5mph), Take-off/Landing: VTOL, Working Voltage: 24V, Working Temperature: -10℃-40℃
Topodrone Fixed-Wing
A Topodrone Fixed-Wing small Unmanned Aerial System (sUAS) and a multispectral camera are employed for topographic surveying. This sUAS is a commercial-grade aerial mapping camera platform designed for the Pixhawk autopilot and carries a RedEdge multispectral camera. This multispectral camera records aerial photographs in the RGB, red edge, and near-IR spectral bands. The Ground Sample Distance (GSD) is 8 cm per pixel per band at 120 m above ground and the capture rate is 1 capture per second (all bands), 12-bit RAW. This sUAS mapper weights a maximum of 2kg with an endurance of 40 minutes, a minimum airspeed of 17 meters per second, and a maximum safe survey area per flight of 1km² while flying 100 meters altitude. This sUAS mapper was enhanced by the Center of Autonomous Sensing and Sampling (CASS). A Piksi Multi GNSS Module replaces the default tuffwing GPS. Piksi Multi is a multi-band, multi-constellation RTK GNSS receiver that provides centimeter-level accuracy at a low cost. The satellite system covers a total of four global systems including the GLONASS (built by Russia), BeiDou (China) and Galileo (Europe), and regional system Japan's QZSS) the global satellite. Mission planner autopilot flight planning software was used for UAS image acquisition in both surveys.![FLEET-4.jpg](FLEET-4.jpg)

Unmanned Aerial System (UAS) coupled with a Miniaturized Radiometer
The DJI Matrice 600 Pro UAS carries a TerraradTech microwave L-band radiometer as a payload. This portable L-band Radiometer (PoLRA) can read the soil moisture from 5-10 cm and has less than 2% error. The unique antenna of this system provides a temperature correction for the full power of the beam width at 37°. The L-band radiometer is one of the most efficient and cost-effective approaches to measuring soil moisture because of its dual-polarization capabilities. The L-band radiometer is a sub-orbital system that measures soil moisture at a high spatial resolution (e.g. 6 m pixel at 10 m altitude a.g.l.) at a frequency of 1-2GHz which is the most promising approach to measuring soil moisture.
Phantom 4 Mica Sensor
The DJI Phantom 4 UAV is designed for precision aerial imaging and surveying. Integrated with a MicaSense RedEdge camera, this UAV is equipped to capture high-resolution multispectral images across five distinct spectral bands: blue, green, red, red edge, and near-infrared (NIR). Utilizing the captured spectral data, the Phantom 4 and MicaSense RedEdge system can compute the Normalized Difference Vegetation Index (NDVI). NDVI is a crucial metric for monitoring and managing vegetation health, providing insights into plant vitality, stress levels, and overall ecosystem health. This gives us insight on how vegetation is associated with soil moisture.
Mavic 3T
The DJI Mavic 3T is an advanced drone designed for professionals requiring highquality thermal imaging, surveying, and mapping capabilities. The Mavic 3T supports multispectral imaging, allowing it to capture data in multiple spectral bands. This feature is vital for agricultural monitoring, environmental studies, and precision farming, providing insights into plant health, soil conditions, and more. This allows us to have a higher resolution of the land surface temperature rather than relying on satellites with a lower resolution.
