Innovation: QZS-3 and QZS-4 join the Quasi-Zenith Satellite System Posted on 09 Feb 2018 in the From the Magazine & GNSS & Innovation categories.

Constellation completed
The first, or prototype, Block I QZSS satellite was launched in 2010 and, based on the positive test results from this satellite, an additional three satellites were launched in 2017, completing a four-satellite constellation. In this month’s column, we examine the recent developments of this unique and innovative navigation system. Read more»

Innovation: Orbit determination of LEO satellites with real-time corrections Posted on 24 Apr 2017 in the Featured Stories & From the Magazine & Innovation categories.

Precision on Board
Described are the results of realistic simulations carried out to precisely position a low-Earth-orbit satellite using a source of real-time GPS corrections actually transmitted by a network of geostationary satellites. Even accounting for data outages, 3D positioning accuracies better than a decimeter have been obtained. Precision on board? Not right now but likely coming real soon. Read more»
