On Friday, July 10, 2026, the International Telecommunication Union’s Radio Regulations Board (ITU/RRB) formally denied a regulatory extension requested by satellite operator Globalstar Inc..
The company had sought an administrative modification to alter its launch and deployment obligations for its French-licensed non-geostationary satellite orbit (NGSO) fleet, which operates under the HIBLEO-X and HIBLEO-4 designations.
Globalstar, which is currently navigating an $11.6 billion acquisition and corporate integration strategy with Amazon.com Inc., petitioned the international body for schedule relief by citing a historical force majeure event. The operator argued that initial hardware manufacturing timelines were severely disrupted when a major earthquake in April 2009 damaged the Thales Alenia Space electronic component fabrication facility in L’Aquila, Italy, where portions of the early hardware payload infrastructure were undergoing assembly. However, the ITU safety and regulatory board determined that the manufacturer disruption did not constitute a valid basis for a modern milestone extension, stating that the operator had failed to complete sufficient risk assessments and supply-chain due diligence regarding its contracted manufacturing sites.
Constellation Framework and Spectrum Parameters
The HIBLEO architecture functions as an integrated Mobile Satellite Services (MSS) network designed to route low-latency voice, tracking data, and emergency messaging services. The technical configurations of the under-construction and operational segments include:
- Operational frequencies situated in the “Big LEO” bands, utilizing 1610–1626.5 MHz (L-band) for user terminal uplink paths and 2483.5–2500 MHz (S-band) for space-to-Earth downlinks.
- International regulatory licensing routed through Globalstar France SAS via the French national framework and filed with the ITU.
- System deployment paths designed to integrate the legacy French-authorized HIBLEO-X constellation with upcoming replacement space stations to maintain persistent orbital coverage.
Regulatory Determination and Operational Exposure
The definitive enforcement of the original launch milestones introduces regulatory complications for the execution of Amazon’s broader Direct-to-Device (D2D) strategy. Under the terms of the pending merger, Amazon intends to fuse Globalstar’s globally harmonized L-band and S-band spectrum assets with its own Project Kuiper broadband infrastructure to support a unified network capable of servicing cellular devices directly from low Earth orbit.
While Globalstar has parallel replacement satellite builds underway with alternative contractors to update its aging second-generation hardware, the rigid milestone ruling by the ITU restricts the company’s ability to defer regulatory deadlines. Corporate legal teams must now coordinate with French regulators to satisfy active operational parameters or risk facing international spectrum coordination constraints that could limit the peak capacity of the combined system ahead of its targeted 2028 deployment window.
