A government report commissioned by Innovate UK, along with the UK Space Agency and the Royal Institute of Navigation, entitled “Economic impact to the UK of a disruption to GNSS”, comes in the wake of troubling incidents for GNSS operators, both the United States and Europe.
Last year a problem with the GPS satellite timing signal triggered alarms and caused an unknown number of outages, and in Europe earlier this year the fledgling Galileo signal crashed due to unspecified ground facility issues.

L3 Interstate Electronics Corporation announced on Tuesday (July 25) that its TruNav GPS is the company’s first Military Code (M-Code) compatible GPS receiver to guide a gun-launched spinning projectile to a target. The guided flight test was conducted at Yuma Proving Grounds by the U.S. Army as part of a series consisting of both guided and unguided rounds.

The R&S ZNLE vector network analyzer. Photo: Rohde & SchwarzRohde & Schwarz has launched the R&S ZNLE vector network analyzer to address the requirements of customers looking to perform RF measurements to characterize components such as antennas, attenuators, filters and PCBs. The new standalone instrument weighs 6 kilograms and has a footprint of just 408 millimeters x 235 millimeters, saving up to two thirds of space on the workbench compared with competitive VNAs, according to the company.

The data is an inevitable “must use” tool for high precision positioning systems used in automated driving vehicles.
While the major part of autonomous driving systems consists of sensors and image recognition technologies, satellite positioning is also a key element used for complementing the precise current position.
