NTIA Files an Inventory of Complementary, Alternative and Augmentative PNT Options in FCC Proceeding on Promoting the Development of PNT

May 27, 2025
25-110

NTIA applauds the FCC's initiative on Promoting the Development of Positioning, Navigation, and Timing Technologies and Solutions. The Commission is seeking to understand and solve the challenges facing the Nation’s current Position, Navigation, and Timing (PNT) system. NTIA submits the attached “Inventory of Complementary, Alternative, and Augmentative PNT Solutions” to aid this important work.

18 GHz Band Report

May 01, 2025

As directed by the 2023 National Spectrum Strategy (NSS), the frequency band 18.1-18.6 GHz (the “18 GHz band”) was identified for study for expanded federal and non-federal satellite operations, consistent with the United States position at the International Telecommunication Union’s (ITU’s) 2023 World Radiocommunication Conference (WRC-23). WRC-23 concluded on December 23, 2023, adding co-primary space-to-space allocations for the intersatellite service (ISS) in this band.

NTIA Comments in Response to FCC Notice of Inquiry on Promoting the Development of Positioning, Navigation, and Timing Technologies and Solutions

April 28, 2025
25-110

In opening this inquiry, the Federal Communications Commission grapples with vulnerabilities in a bedrock United States Government-provided technology, the Global Positioning System (GPS). 

The Commission’s “whole of government” approach aligns with Executive Branch operations, authorities and initiatives. In these comments, NTIA highlights the key roles Federal agencies play in sustaining and improving Positioning, Navigation and Timing (PNT) services.

NTIA Comments on Facilitating Opportunities for Advanced Air Mobility

April 22, 2025
24-629
NTIA supports updating the rules of the Federal Communications Commission (FCC or Commission) in order to boost the development of new aviation sectors such as Advanced Air Mobility (AAM), including piloted and remotely piloted aircraft systems. In doing so, safety of all aviation systems, including emerging ones, must top all concerns.

Direct-to-Device Services Request for Comment

December 19, 2024
The National Telecommunications and Information Administration (NTIA) is seeking information and public comment on the potential impact on the GPS L1 signal at 1575.42 MHz of the increasing deployment of mobile devices capable of operating on satellite systems in the L-band at 1610-1660.5 MHz. Under current FCC rules, these devices are permitted to operate subject to a substantially less restrictive out-of-band emission limit than similar devices transmitting on the same frequencies and connecting to terrestrial base station systems. NTIA is seeking public comment on the risk of interference posed by this increased deployment of mobile devices capable of operating on L-band satellite systems at 1610-1660.5 MHz, as well as potential mitigation options to safeguard GPS systems while facilitating the potential benefits of direct-to-device services (D2D services).

An Analysis of Aggregate CBRS SAS Data from April 2021 to July 2024

Report ID
NTIA Report 25-575
November 18, 2024
This report presents an analysis of aggregate Citizens Broadband Radio Service (CBRS) Spectrum Access System (SAS) data reported quarterly from April 1, 2021, to July 1, 2024. The data provide insights into the growth of CBRS, the impact of dynamic spectrum sharing, the role of General Authorized Access (GAA) usage, and CBRS’s role in rural and urban wireless connectivity.

NTIA Comments on Allocations for Non-Federal Space Launch Operations

November 15, 2024
13-115
NTIA, consistent with its responsibility to ensure that the views of the Executive Branch on telecommunications matters are effectively presented to the Commission, provides these comments reflecting the views of DAF and DON in response to the above referenced Second Further Notice of Proposed Rulemaking.

2023 Commercial Spectrum Enhancement Act (CSEA) Report

October 16, 2024
This report covers the period from January 2023 through December 2023 with the funds reported reflecting expenditures for Fiscal Year (FY) 2023. As authorized by the CSEA, the Spectrum Relocation Fund (SRF) provides a centralized and streamlined funding mechanism through which federal agencies can recover the costs associated with relocating their radio communications systems or sharing the reallocated spectrum.

National Spectrum Strategy August Multistakeholder Meeting

August 07, 2024

Summary

This notice announces a public meeting for providing input to spectrum band studies directed by the National Spectrum Strategy and National Spectrum Strategy Implementation Plan, which instructed the National Telecommunications and Information Administration (NTIA) to establish a multistakeholder forum for non-Federal stakeholders to engage with the Federal agencies conducting the studies. This is the first of what NTIA expects will be a series of public multistakeholder meetings held approximately every other month.
