1.3.5.1 Classification on the Basis of Spectrum Perspective
ОглавлениеInternational Telecommunication Union (ITU) classifies unmanned aircraft broadly in three categories on the spectrum perspective. It is highly dependent on the range, cruise speed, and altitude of the unmanned aircraft. The Table 1.1 depicts the same classification [21]:
Table 1.1 UA categories on the basis of spectrum perspective.
| Category of unmanned aircraft (UA) | Weight (kg) | Maxim height/ altitude (m) | Cruise speed (km/h) | Endurance (h) | Maximum range (km) |
| Small | <25 kg | <300 m | <111 km/h | <5 h | Visual LoS <3 km |
| Medium | 25–2,000 kg | 300–5,500 m | 111–185 km/h | 5–30 h | RF LoS 150–250 km |
| Large | >2,000 kg | >5,500 m | >185 km/h | >30 h | BeyondRF LoS |
