The GPS Innovation Alliance (GPSIA) sent a letter to FCC Commissioner Michael O’Rielly on July 30 regarding Ligado Networks. The letter highlights what appears to be different characterizations of the engineering information in the FCC’s record, and suggests that these contrasting statements “support a careful re-examination of the bases of the Ligado Order and a stay of the decision while that occurs.” “GPSIA appreciates your continued interest and efforts in this proceeding, and your willingness to consider whether a stay of the Ligado order may be appropriate,” the letter states. “As the record in this proceeding makes clear, sound technical analyses were conducted on Ligado’s network by DOT — a neutral third-party U.S. government expert on GPS. Further evaluation of those analyses should prompt the Commission to set aside the Ligado order so that its understanding of the DoT ABC Report can be better aligned with the authors of the report.” Read the full text of the letter. Hold on Third FCC Chairmanship. In a related report, the chairman of the Senate Armed Services Committee Sen. Jim Inhofe (R-Okla.) on July 28 placed a hold on the nomination of O’Rielly to another five-year term chairing the commission. Inhofe said he would block O’Rielly until the nominee “publicly commits to vote to overturn the current Ligado order,” according to a report from Space News. “Over the past few months, I have sent letters, held hearings and called countless officials to highlight what we all know to be true: the FCC’s Ligado order is flawed and will lead to significant harm to our military and the thousands of individuals and businesses that rely on GPS,” Inhofe said.
