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.

Navigating in Space

Figures 1 & 2

Spacecraft in low Earth orbit (LEO), at altitudes below 3,000 kilometers, remain within the main Global Positioning System (GPS) signals’ Earth coverage. Spacecraft employing GPS at these altitudes enjoy signal availability and navigation and timing performance emulating that of terrestrial users.

SDX GNSS Simulator Covers Four Satellite Navigation Systems

SDX GNSS Simulation with Four Simultaneous Constellations

With the addition of BeiDou B1 and B2 signals, Longueuil, Canada-based
Skydel’s (SDX) GNSS simulator now covers the four global navigation
satellite systems, the company said. SDX also added Galileo signals E5a
and E5b.

With these new updates, SDX said it is now possible to create a GNSS
simulation with a four-constellation, dual-frequency test scenario on a
single software-designed radio (SDR). The SDX GNSS simulator is ideal
for engineers, designers, and research institutes, the company said.

Skydel now offers these satellite signals:

NovAtel and Stanford Sign Autonomous Vehicle Study Agreement

NovAtel has signed a contract with Stanford University for a study to determine how GNSS technology can deliver a positioning system that meets safety and accuracy requirements for autonomous land vehicles, the company said.

NovAtel said the study, to be conducted at Stanford’s GPS Research Laboratory, will build on similar aircraft research. In addition, the research will include concepts for high integrity carrier-phase algorithms, threat models, and safety monitors for improving autonomous vehicle transportation, the company said.

GNSS Notes from InterGEO

Rob Hranak, Swift Navigation vice president of business development, talks about Piksi Multi at InterGEO

This year’s InterGEO in Hamburg, Germany, featured the latest in geospatial wizardry including new navigation and positioning components and boards not only driving progress in the surveying and mapping industries, but also feeding into the wider GNSS user community.

San Francisco-based Swift Navigation came into InterGEO brandishing the all-new Piksi Multi, described as the world’s first affordable multi-band and multi-constellation receiver.

ITAR Controls on Military GNSS Receivers Updated

The State Department last week published its final rule that updates export controls on military GNSS receivers through the U.S. Munitions List (USML).

The State Department-controlled USML, governed by the International Traffic in Arms Regulations (ITAR), moves GNSS receivers out of the USML spacecraft systems and related articles category. Instead, GNSS receivers are now controlled under the guidance and navigation systems category.
