The GPS Innovation Alliance (GPSIA) is deeply disappointed by today’s decision, which appears to ignore the well-documented views of the expert agencies charged with preserving the integrity of GPS, specifically on the critical issue of what constitutes harmful interference to users of Global Navigation Satellite Systems (GNSS). GPSIA has consistently advocated for adoption of the 1 dB Standard as the only reliable mechanism that provides the predictability and certainty to ensure the continuation of the GPS success story, with the support of the Department of Defense, the Department of Transportation and numerous other federal agencies. The 1 dB Standard for radiofrequency-based services is critical for GNSS. The FCC’s press release refers to conditions placed on Ligado’s application to prevent harmful interference and GPSIA and its members intend to carefully review the details of today’s order while continuing to vigorously advocate for promoting, protecting and enhancing GPS.
