The digital outputs of a four-channel antenna processing chain consisting of a four-element squared phased array and a 4-coherent channels front-end are processed to identify the presence of a jamming signal. The processing unit then implements a spatial filter to minimize jammer impact. The reconstructed signal is input to a COTS/SDR receiver designed to work in a typical railway environment.
An extensive and significant body of technical information on inertial navigation, including detailed instruction, technical papers and use cases, has appeared online. This valuable resource is openly available to engineers, designers, integrators, and specifiers working on UAVs, aerial and ground survey and mapping, construction, surveillance and reconnaissance, satellite communications, military and much more.

The third next-generation GLONASS-K navigation satellite, postponed several times, will now take place in late August or early September, according to reported statements by Russian space industry sources. This marks a long-delayed step along a road towards interoperability with other GNSS. The first GLONASS-K satellite was launched in 2011 and a second one in 2014.

Galileo will provide a High Accuracy Service (HAS) with positioning performance in the 20-cm range, disseminating Precise Point Positioning (PPP) corrections through the Galileo E6-B signal. Test results of a data encoding and dissemination scheme in different user environments demonstrate a reception time of the corrections in a few seconds in good channel conditions, and less than half a minute with severe channel impairments.
