Anomalous GPS signals reported from SVN49

June 6, 2017By

Researchers at the Politecnico di Torino university detected spikes in the L1 signal spectrum. The origin of the spikes was identified as the transmission of a non-standard code from a non-operational GPS satellite. This story reports on signal observations performed to identify the source of the interference and the impact it could have on GNSS signal processing. read more

eLoran and Loran testing underway in late June

June 5, 2017By

The Loran sites at Havre, Montana; George, Washington; and Fallon, Nevada, will continuously broadcast from 0900 (MST) June 20  through 1200 (MST) on June 30. The sites will operate on the 5990 rate but occasionally may operate at other rates. Only the site at Fallon will operate as an eLoran site. The sites at Havre and George will operate as... read more
