A
CRITICAL REPORT - NEARLY 17,000 SATELLITES IN ORBIT AND THE GROWING SPECTRUM CHALLENGE
CREDITS & SOURCES: CRITICAL COMMS / WIRELESS INSTITUTE OF AUSTRALIA (WIA) / IARU
REGULATION, RADIO SPECTRUM, AND SATELLITE COMMUNICATIONS TECHNICAL BULLETIN
ISSUE DATE: OCTOBER 20, 2026
VALID: OCTOBER 20, 2026 ONWARDS
ISSUED VIA BPQ32 NODE HP2DFA-5 IN PANAMA
======================================================================
1. ORBITAL CONGESTION OVERVIEW (LOOK UP SPACE BAROMETER)
======================================================================
ACCORDING TO A REPORT BY *CRITICAL COMMS* DRAWING ON THE FOURTH EDITION OF THE
*SPACE BAROMETER*, ACTIVE SATELLITES ORBITING EARTH HAVE REACHED **16,819**, A 29INCREASE OVER THE PREVIOUS TWELVE MONTHS.
- **LAUNCH VOLUME**: 4,737 SATELLITES LAUNCHED OVER THE REPORTING PERIOD.
- **TRACKED OBJECTS**: OVER 34,000 OBJECTS (SATELLITES, ROCKET STAGES, AND DEBRIS).
- **CONSTELATION DOMINANCE**: SPACEX STARLINK LEADS WITH 11,041 ACTIVE SATELLITES
(INCLUDING ~640 DIRECT-TO-CELL UNITS), WHILE CHINA RAPIDLY EXPANDS TO 1,434.
======================================================================
2. IMPLICATIONS & THE AST SPACEMOBILE PRECEDENT
======================================================================
THE RAPID EXPANSION OF COMMERCIAL CONSTELLATIONS RAISES SERIOUS CONCERNS FOR
SPECTRUM MANAGEMENT AND FREQUENCY COORDINATION:
- **FCC RULING**: IN APRIL 2026, THE US FCC AUTHORIZED AST SPACEMOBILE TO CONDUCT
EMERGENCY TT&C OPERATIONS USING FREQUENCIES WITHIN THE **430–440 MHZ AMATEUR BAND**
OUTSIDE THE UNITED STATES.
- **IARU WARNING**: THE INTERNATIONAL AMATEUR RADIO UNION EXPRESSED CONCERN OVER
THE PRECEDENT SET BY THIS DECISION REGARDING COMMERCIAL ENCROACHMENT.
- **70-CENTIMETER THREAT**: THIS DEVELOPMENT DIRECTLY THREATENS REPEATERS, SATELLITES,
AND WEAK-SIGNAL EXPERIMENTATION ACROSS THE VITAL 70-CM UHF SPECTRUM.
======================================================================
3. BEYOND MERE LEGAL FREQUENCY ALLOCATIONS
======================================================================
WHILE RETAINING FREQUENCY ALLOCATIONS IS IMPORTANT, THE REAL DANGER LIES IN WHETHER
THOSE FREQUENCIES REMAIN USABLE AMID GROWING UNWANTED EMISSIONS, AGGREGATE
INTERFERENCE, AND RECEIVER OVERLOAD FROM ADJACENT OR OVERLAPPING COMMERCIAL SYSTEMS.
- **ADVOCACY IMPORTANCE**: WITH WRC-27 APPROACHING IN LATE 2027, EFFECTIVE ADVOCACY
THROUGH NATIONAL SOCIETIES (LIKE WIA) AND THE IARU IS MORE CRITICAL THAN EVER.
