Controlled reception pattern antennas (CRPAs) are being used to counter the significant threats posed by malicious jammers (beam-nulling) and improve signal reception (beam-forming). Testing these systems has several defined stages, and requires powerful, flexible and very accurate test equipment. From conducted wavefront testing to realistic over-the-air scenarios, Spirent’s industry-leading solutions are powering the next generation of robust PNT technology.
Testing the electronics and software behind the antenna is a key element of effective CRPA testing. Spirent’s GSS9000 is the industry’s leading test platform – designed and built specifically for the most challenging GNSS performance and resiliency tests. Supporting all existing civilian signals, restricted GPS/Galileo signals, and the bespoke design of customers’ own non-ICD GNSS signals, the GSS9000 features:
The final stages of CRPA testing and development is often over-the-air (OTA) testing for angle of arrival (AOA) verification. Spirent’s GSS9790 builds on the leading GSS9000 platform, adding the capability to individually control up to 10 independent but synchronous transmitters using just a single signal generator, creating a realistic representation of the satellite skyplot and trajectories. In addition, the GSS9790 fully supports synchronisation with additional boxes where required, maintaining the same high-level performance. The GSS9790 features:
Spirent’s CRPA test solutions build on experience gained over more than 30 years of supporting GNSS application development by the top experts in this field. Our systems offer the proven performance and reliability that our customers demand.
