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.

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.

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.

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.

The Munich Satellite Navigation Summit and exhibition will take place at the Residenz Muenchen in Munich, Germany on March 14 – 16, 2017.
Register here. Early bird rate until January 17, 2017.
The theme for this year’s summit is “GNSS: Is It Time for Backup?”
The technical program includes plenary discussions and updates on the
main activities in worldwide satellite navigation systems, including:
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 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.
