Mike Veth: Engineering Meets the Wild Blue Yonder

Veth proudly poses with his RV-8A fuselage components securely fastened in a jig. The RV-8A is a two-place, tandem, experimental aircraft that is home-built from kit components. When completed, he plans to use the aircraft as an experimental navigation testbed.

SIDEBAR: Mike Veth’s Compass Points

Over the course of Lt. Col. Michael Veth’s 20-year career in the U.S. Air Force (USAF), certain navigation technologies may have changed dramatically, but working toward increased accuracy has remained a constant.

The PNT Boom

FIGURE 1: Potential components of a multisensor integrated navigation system

The navigation world is booming with new ideas at the moment to meet some of the greatest positioning challenges of our times. To realize demanding applications — such as reliable pedestrian navigation, lane identification, and robustness against interference, jamming and spoofing — we need to bring these different ideas together.

GNSS and Ubiquity

GNSS and Ubiquity

Chris Rizos, University of New South Wales

GNSS is in a class of its own and the positioning/navigation/timing (PNT) technology of choice for most applications. Why wouldn’t we always use it?

It is affordable, it is a mature technology with many form factors, and its level of performance spans several orders of magnitude — millimeters to meters. There are a bewildering number of permutations of user equipment, augmentation solutions, processing algorithms, and operational procedures to choose from.

However. . . .

Markets and Multi-Frequency GNSS

Markets and Multi-Frequency GNSS

FIGURE 1: Proposal to have a single chip GNSS receiver with additional pins to allow for the inclusion of an additional radio

Q: What will limit the spread of multi-frequency GNSS receivers into the mass market?

A: To set the scene, we need to define our terms of reference. By multi-frequency we mean receivers that operate with navigation signals in more than just the standard upper L-band from about 1560–1610 MHz where we find GPS L1, Galileo E1, Compass B1, and GLONASS L1. The obvious additional frequency is the lower L-band, from about 1170 to 1300 MHz, where again the same four constellations have signals.
