There are many good reasons for getting excited about highly automated vehicles, or HAVs, which is the acronym used by the National Highway Traffic Safety Administration (NHTSA). HAVs can make driving more fuel- and time-efficient. They can significantly reduce traffic congestion and emissions by driving a precise speed, minimizing lane changes, and maintaining an exact distance to neighboring cars. They can also increase accessibility and mobility for disabled and elderly persons.By Inside GNSS

Q: Is it possible to build a low-cost system to detect and locate a single GNSS jammer in near-real time?
A: GNSS jammers are an ongoing threat to the reliable use of GNSS. The problem of geolocating GNSS jammers can be addressed using a time-difference-of-arrival (TDOA) processing technique; however, this problem is quite different than geolocating jammers in other radio frequency systems. The two main differences are:
(1) No GNSS are available to use as a timing reference.By Inside GNSS
Spirent Communications plc has announced the availability of PT TestBench — software designed to help technology, system and application developers build more accurate positioning functions more quickly. According to the company, the testing, analysis and reporting package automates testing of GPS and other global navigation satellite system (GNSS) receivers, so higher quality systems are brought to market faster and more reliably.By Inside GNSS
The U.S. Air Force Space and Missile Systems Center (SMC) says it continues to work on GPS III ceramic capacitor testing and plans to have an updated launch schedule published late next month.
As Inside GNSS reported, the first GPS III satellite’s delivery, originally scheduled for August, was delayed by four months because of a Lockheed Martin subcontractor’s failure to test a ceramic capacitor.By Inside GNSS
Trimble has announced that the Hitachi Construction Machinery’s ZX200X-5B semi-automatic excavator is now available in Japan with the GCS900 Grade Control System.
The system uses GNSS, laser, sonic, or total station technology, to position the heavy machinery’s blade or bucket in real-time, for significant reduction in material overages and improving the contractor’s productivity, the company said. The unit makes design surfaces, grades, and alignments accessible to the operator inside a cab, Trimble said.By Inside GNSS
