Xona, GPSIA Clashing Over Xona's PNT Constellation Plans

Xona Space Systems' proposed 258-satellite positioning, navigation and timing services constellation (see 2307120002) raises technical and policy issues that need addressing, such as criteria for approving satellite networks that use spectrum allocated for radionavigation satellite services (RNSS), given the precedent that would be established in this proceeding, GPS Innovation Alliance told the FCC Space Bureau last week. It was replying to Xona's opposition to GPSIA's petition to deny. In its opposition to the petition earlier this month, Xona said its system won't degrade or reduce spectrum availability for existing GPS operations or other U.S.-authorized RNSS operations, or foreclose future RNSS operations in the U.S. It said GPSIA's push for aggregate interference protection isn't backed by U.S. rules, precedent or policies. GPSIA in its reply said Xona should do testing with actual global navigation satellite system receivers. "This would provide assurance that unanticipated effects will not manifest themselves," it said.
