UK/US Deal on GPS Signal Patent Omits Galileo Version

A recently announced deal between the United States and the United Kingdom to revoke the UK’s surprise patents on a key GPS technology has a glaring omission: Intentionally left out of the agreement are patents on the European Union’s version of the technology, a signal structure important to enabling Europe’s Galileo system to work seamlessly with America’s GPS constellation.

Markets and Multi-Frequency GNSS

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.

The GNSS Merry Go Round

The whole GNSS world should have a warm spot in its heart for centripetal forces.

After all, a centripetal force — in this case, gravity — is what keeps planets in rotation around our Sun and satellites, around the Earth.

Centrifugal force, of course, is what throws us off a merry-go-round or carousel. Centripetal force is what keeps us on board.

For those on a merry-go-round, the centripetal force is not gravity, but rather the tensile strength of our arms pulling us toward the center of rotation, at right angles to the motion of our seats.

More Than Money Worries

Navigation users may benefit from GPS modernization sooner than expected thanks to an apparent shift in the schedule of the modernized GPS ground control segment still under development.

The change means that full operational implementation of the new signals will come earlier in the delayed modernization of the operational control Segment (OCS).

The GNSS Quartet

The world’s four GNSS programs aren’t exactly a classical quartet, weaving Mozart stanzas in disciplined execution.

They are more like a new jazz combo, riffing off one another while still trying to get in the groove.

Whatever image the metaphor evokes, if the world’s GNSS programs want to hit that high note of interoperability (to which they all say they aspire), the operators of GPS, GLONASS, BeiDou, and Galileo must learn to harmonize better.

AFRL Selects Surrey Satellite US to Evaluate Small Satellite Approach to GPS

The Air Force Research Laboratory (AFRL) has selected Surrey Satellite Technology US LLC (SST-US), of Englewood, Colorado, to investigate cost reduction and augmentation of the current GPS constellation through the application of a small satellite approach.

AFRL has contracted with SST-US to identify and analyze how small satellites can improve aspects of GPS system performance, such as accuracy, coverage, and robustness at costs far below those of past procurements.
