GNSS and Human Flight
Dressing up in a superhero costume and flinging oneself out of an airplane might sound like a good idea to a 20-something skydiver. But is it science? More importantly, can a GNSS-outfitted wingsuit be turned into a free-falling human testbed that helps design better products and applications? Andrew Levson and colleagues at NovAtel plan to find out.
First Acquisition and Tracking of IOV Galileo Signals
Europe’s GNSS program — Galileo — launched two in-orbit validation satellites in October, the first elements of the system’s fully operational constellation. In this article, a team of Italian researchers present the initial results of their analysis of the Galileo signals.
How can pseudorange measurements be generated from code tracking?
What began, in the words of the Defense Department, as a “force enhancer” has become an economy enhancer of enormous value.
Two or more modernized GNSS signals transmitted on the same carrier produce varying amplitudes that reduce the power amplifier efficiency and result in the need for aligning the group signal amplitude. Here, two Russian signals experts introduce a new symmetrized signals class that enables significant reductions in the loss factor created during this amplitude alignment. The authors also propose optimal com¬binations of three and four signals when exploiting multiple GNSS systems and offer an improved design for GLONASS L3 and L5 signals.

Learning inertial navigation and error propagation equations can be daunting for those with a GNSS background
Inertial technology, rather than being eclipsed by GNSS, has found new life on its own and in integrated systems. But engineers from both sides of the divide have much to learn about the other. This is one in a series of sponsored articles by NovAtel.
