A jammer-hunting UAV employs a radio frequency (RF) detection system and a navigation control scheme. The RF detection component uses a directional antenna and the unmanned aerial vehicle’s (UAV’s) ability to rotate to determine a bearing to the jammer. The navigation control scheme selects a trajectory for making bearing measurements that enable rapid jammer localization, based on three bearing calculation methods:... read more
The last Block IIF satellite, launched on Feb. 9, is active. “All-in-view” tracking stations of the International GNSS Service (IGS) network have been receiving its signals since Feb 10. The satellite’s designation is PRN32/SVN70. That PRN is already included in the analysis by the Center for Orbit Determination in Europe (CODE). The IGS orbit products will now cover 57 satellites (32 GPS plus 25... read more
