Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	10. COMMITMENTS AND CONTINGENCIES Updated Services Agreements The Updated Services Agreements set forth the primary terms for the Company to provide expanded services to the Customer and incur costs related to the Extended MSS Network, which primarily relate to the construction of new gateways and the upgrade of existing gateways as well as new satellite construction and launch services, including both the replacement satellites related to the Phase 2 Services Period and the third-generation satellites related to the Extended MSS Network. The Updated Services Agreements have an indefinite term but are terminable by the Customer at any time upon advance notice or a force majeure event, or by either party upon the occurrence of certain events of default. The Updated Services Agreements obligate the Company to comply with various commitments. Refer to Note 2: The Merger Agreement for discussion of the Mergers and the related amendments to certain arrangements with the Customer, including the SOW Amendment. Satellite Procurement Agreements In February 2022, the Company entered into a satellite procurement agreement with MDA Space pursuant to which the Company will acquire at least 17 satellites (and up to 26 satellites) to replace its HIBLEO-4 U.S.-licensed system with an amended contract price of $329.3 million for 17 of the replacement satellites. In addition, MDA Space provided a satellite operations control center for $5.0 million as well as other equipment for $4.2 million. The projected delivery dates were later than the dates specified in the satellite procurement agreement. The Company is contractually entitled to receive liquidated damages from MDA Space based upon the terms of the satellite procurement agreement due to MDA Space's failure to meet delivery milestones and the parties are discussing this matter. Any damages would reduce amounts owed to MDA Space when realized or realizable. The first set of replacement satellites was delivered in April 2026 and after certain repairs re-delivered in July 2026. The first set of replacement satellites is scheduled to be launched in August 2026. The second set of replacement satellites is scheduled for delivery later in 2026. In February 2025, the Company entered into another agreement with MDA Space pursuant to which the Company will acquire more than 50 third-generation satellites related to the Extended MSS Network. The total contract price for these satellites is $775.0 million. Launch Services Agreements In each of August 2023 and June 2025, Globalstar entered into a Launch Services Agreement with SpaceX and certain related ancillary agreements (collectively, the "Launch Services Agreements"), providing for the launch of the first and second sets, respectively, of the 17 replacement satellites that the Company is acquiring pursuant to the 2022 satellite procurement agreement with MDA Space. As a result of the delays experienced with the replacement satellites (discussed above), the Company and SpaceX established an updated launch window in August 2026 for the first set of replacement satellites. In October 2024, the Company entered into a separate agreement with SpaceX for the launch of the third-generation satellites related to the Extended MSS Network. Expanded Ground Infrastructure The Company has ground infrastructure purchase commitments with its third party antenna and other equipment manufacturers to support the Extended MSS Network. Outstanding purchase commitments to support the Extended MSS Network ground infrastructure as of June 30, 2026 were approximately $209.6 million. Funding for Phase 2 Service Period Asset Procurement Under the Service Agreements, subject to certain terms and conditions, the Company expects to receive payments equal to 95% of the approved capital expenditures under the satellite procurement agreement for the replacement satellites, launch services agreements for such replacement satellites and other ancillary equipment and launch costs (to be paid on a straight-line basis over the 12-year design life of such replacement satellites) beginning with the commencement of the Phase 2 Service Period. Funding for Extended MSS Network Asset Procurement As discussed in more detail in Note 3: Special Purpose Entity, the Updated Services Agreements provide for prepayments from the Customer for approved capital expenditures associated with the Extended MSS Network. As of June 30, 2026, the Company incurred $0.8 billion of the $2.0 billion projected spend for the Extended MSS Network. The Company will continue to incur these costs until the assets are placed into service.
