How to Read a BR IFIC Entry, Field by Field

A single BR IFIC entry packs a lot into a small number of fields. Knowing what each one actually tells you turns a wall of technical data into a quick, useful read.

Field	What it tells you
Administration (ADM)	The national administration that submitted the filing on the operator's behalf — not necessarily where the operator itself is based, since filings go through a sponsoring administration.
Notice type	Where the filing sits in the ITU process — an early-stage API/A, a formal CR/C coordination request, or later stages. See our notification types reference for the full picture.
BR IFIC / WIC number	The publication in which this entry appeared — effectively a timestamp for when it became public, which matters for priority.
Satellite / network name	The name under which the filing was submitted. The same physical satellite can appear under several related filings over its life.
Frequency range & bandwidth	The core of any overlap check — which part of the spectrum the filing actually claims.
Polarization	Linear or circular, and orientation. Two overlapping bands with opposite polarization carry meaningfully less practical interference risk.
EIRP & antenna gain	A proxy for how much power is likely to actually reach a given direction — high EIRP toward a shared band is a bigger flag than a weak, wide beam.
Orbital parameters	Orbital position for GSO, or orbital plane characteristics for NGSO. Often the deciding factor: two overlapping bands pointed at completely different parts of the sky may never interact in practice.

A practical reading order

When triaging a list of candidate overlaps, most engineers end up reading in roughly this order: notice type first (how seriously to take it), frequency overlap second (is it real and how much), polarization and power third (does it matter physically), and orbital geometry last (does it matter geographically). Skipping straight to detailed geometry on every candidate wastes time on entries that would have been ruled out at the polarization step.
