China’s Industry Gets with Compass Program
Inside GNSS editor Glen Gibbons provides a first-hand report
from the NaviForum Shanghai conference, where Compass received attention
from Chinese GNSS manufacturers and a high-level delegation from the
Integrating Vision Measurements for Navigation in Signal-Challenged Environments
As accurate and widely available as GNSS service is, it still cannot be fully accessed everywhere, at all times, and under all conditions. In this article, researchers investigate the feasibility of combining GPS and vision-based measurements for navigation in challenged GNSS environments, such as urban canyons and indoors.
This article concludes our series about the use of simulators and simulation techniques in developing GNSS receivers. Part Three examines various simulator designs and whether the specifications of any given simulator equpment is suitable for a particular test.
A team of European researchers continue their assessment of the potential use of S-band spectrum for transmitting GNSS satellite signals, addressing the issue of RF compatibility with nearby mobile satellite services as well as the possible use of an orthogonal frequency division multiplexing (OFDM) signal modulation.
Keeping track of GNSS progress
We are enjoying the fruits of almost invisible labor - the efforts of
those who put satellites into the sky and signals on the air.
