Russia first broached the idea of erecting the domed antenna structures here nearly two years ago, saying they would significantly improve the accuracy and reliability of its version of the Global Positioning System, the American satellite network that steers bomb-bearing warplanes to their targets and wayward motorists to their destinations.
Congressional Republicans, however, harbored suspicions that Russia had nefarious motives behind its plan, which the State Department supported as a means to mend bruised relations between the two rival nations. The Pentagon and the Central Intelligence Agency sided with congressional critics, concerned about handing the Russians an opening to snoop on the United States within its borders.
The monitor stations have been a high priority of President Vladimir V. Putin for years as a means to improve Moscow’s global positioning network — known as Glonass, for Global Navigation Satellite System — not only to benefit the Russian military and civilian sectors but also to compete globally with GPS.
As the White House sought to reconcile the internal squabbling among government agencies, skeptical members of the intelligence and armed services committees in Congress intervened in recent weeks to deal a near-crippling blow to the prospect of Glonass stations in the United States.
