IOT
Pronunciation: EYE-oh-TEE
Also written as: IOT — In-Orbit Testing
The formal verification phase conducted after LEOP in which a satellite's payload performance is measured and confirmed against design specifications.
Full Definition
IOT follows the Launch and Early Orbit Phase and involves systematic testing of all satellite payload functions—transponder gain, frequency response, EIRP, saturation flux density, and beam coverage—from the ground. Results are documented in an IOT report, which is often a contractual deliverable to the satellite operator or customer. Editors must note that in this industry context 'IOT' means In-Orbit Testing, not 'Internet of Things', and should flag the acronym if used in a mixed-technology document. IOT reports require careful editorial attention to unit consistency and tabular formatting.
Usage
Usage note: In satellite documents, 'IOT' always means In-Orbit Testing. Flag ambiguity if 'IoT' (Internet of Things) appears in the same document.
In Context
- "The IOT report confirmed that all 32 transponders met their specified EIRP levels within ±0.5 dB." — IOT summary report
- "Editors should ensure the IOT section heading is not confused with IoT (Internet of Things) references elsewhere in a converged network document." — Editorial style note
