Anti-jam technology: Demystifying the CRPA

April 12, 2017By
Jam-1-O

Controlled reception pattern antennas (CRPAs, pronounced “serpers”), adaptive antennas, null-steering antennas, beamforming antennas… You’ve probably heard of at least one of those terms in any discussion around GPS anti-jam technology for defense. Because they are all terms that describe essentially the same thing: a specialized antenna that helps protect GPS receivers from interference and jamming. But what exactly are they? Where... read more

Narrowband IoT (NB‑IoT) is a new way of communicating with the “things” in Internet of Things that was standardized by 3GPP in June 2016. The latest mobile broadband standard, NB-IoT is aimed at devices that need to communicate small amounts of data over long periods in hard-to-reach places. It connects devices through existing GSM and LTE spectrum networks. NB-IoT uses... read more

Innovation: Mitigating interference with a dual-polarized antenna array in a real environment

FIGURE 2. CW interference scenario.

Double Take
A diversely polarized antenna array combines signal processing in the spatial and polarization domains for significant improvement in receiver robustness against interference. The C/N0 of line-of-sight components is improved since the receiver can use the power present in the left-hand circularly polarized channels, and also interference mitigation improves. read more

Tracking RFI: Interference localization using a CRPA

Eurocontrol-airtrafficcontroller-airlines-O

A controlled radiation-pattern antenna can preserve GNSS positioning while providing at least an azimuth angle towards an interference source. If integrated with an attitude and heading reference system, only a few lines of position pointing towards the RFI source could provide a fast indication of the probable ground location. read more
