Hitachi Uses Trimble Grade Control System

Trimble GSC900 Allows Precision Excavation

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.

NASA to Launch Satellite-Based GNSS Hurricane Watch

NASA plans to launch the Cyclone GNSS (CYGNSS) hurricane mission aboard a Pegasus XL rocket on December 12 from Cape Canaveral Air Force Station in Florida. CYGNSS, which is NASA’s first Earth science small-satellite constellation, will help improve hurricane intensity, tracking, and storm surge forecasts, the agency said.

NOAA Expands GNSS Data Sources for Weather Prediction

NOAA Expands GNSS Data Sources for Weather Prediction

The National Oceanic and Atmospheric Administration (NOAA) will purchase data from small commercial satellites to expand its GNSS radio occultation (RO) efforts to better predict weather.

In September NOAA, through the government’s Commercial Weather Data Pilot program, awarded contracts to San Francisco, California-based Spire Global ($370,000) and GeoOptics ($695,000), of Pasadena, California, to provide RO data. This data will be used to assess whether commercially provided information can be incorporated into the agency’s weather models.

Challenges of Ray-Tracing for GNSS Applications

Q: What are the challenges of ray-tracing for GNSS applications?

A: Simulating the propagation and reception of GNSS signals in complex environments is a challenging task. Indeed, the user always has to trade off between the computation time and the reliability of the output. Moreover, the motion of GNSS satellites, atmospheric effects, and building geometry are always difficult to model.
