L-band SATCOM (approx.)
≈1–2 GHz (system-dependent)
A general frequency neighborhood, not a single fixed channel, used by several commercial mobile-satellite systems (e.g., Inmarsat- and Iridium-class services) for beyond-line-of-sight (BLOS) command/control and payload relay links to larger (Group 3 and above) uncrewed aircraft.

Band facts
| Field | Value |
|---|---|
| Frequency | ≈1–2 GHz (system-dependent) |
| System | Satellite communications |
| Category | SATCOM — Beyond-Line-of-Sight Relay |
| Band class | UHF |
| ITU region | Global — specific channel assignments within this range are set per-system under ITU Radio Regulations Article 5 mobile-satellite allocations and national/operator frequency coordination |
| Standard | ITU Radio Regulations, Article 5 (mobile-satellite service allocations) |
Why this band matters
The general band larger, longer-range UAS use for BLOS control and data relay via commercial satellite links, as distinct from the direct-RF ISM control links used by smaller UAS.

Frequently asked
What frequency is L-band SATCOM (approx.)?
L-band SATCOM (approx.) operates at ≈1–2 GHz (system-dependent). A general frequency neighborhood, not a single fixed channel, used by several commercial mobile-satellite systems (e.g., Inmarsat- and Iridium-class services) for beyond-line-of-sight (BLOS) command/control and payload relay links to larger (Group 3 and above) uncrewed aircraft.
Why does the L-band SATCOM (approx.) band matter?
The general band larger, longer-range UAS use for BLOS control and data relay via commercial satellite links, as distinct from the direct-RF ISM control links used by smaller UAS.
