New technologies are emerging to fill the gap left by GNSS services whose signals cannot penetrate indoor spaces. Using everything from triangulation and flickering light bulbs to the Earth’s magnetic field, start-up companies are lining up to help brick-and-mortar retailers beat back their online competition with location-inspired service.

Although delayed for a year for lack of funding — and delayed yet again by the government shutdown — research to help set GPS-protecting interference standards appears poised to get underway.
The ABC or Adjacent-Band Compatibility Assessment is part of a broad plan to draft spectrum interference standards covering all GPS civil receivers. The approach would give potential users of frequencies neighboring the GPS band clear limits so they can test and plan accordingly.

Hemisphere GNSS has launched the Eclipse P306 and P307 multi-frequency GPS, GLONASS, and BeiDou modules, the first products to incorporate the company’s new SX4 ASIC.
With 372 channels, the modules can simultaneously track code and carrier phase signals on up to 89 satellites, are are Galileo- and QZSS-ready, and can be configured to address several diverse applications through software, according to the company.

A group of top frequency experts recommended last week that the Federal Communications Commission (FCC) conduct a pilot test of the concept of “harm claim thresholds” (HCTs), an approach that requires receiver manufacturers to build devices capable of withstanding a predetermined level of interference from users in adjacent frequencies.

JAVAD GNSS has introduced the Triumph-LS, a complete real-time kinematic survey system including an 864-channel receiver capable of receiving and processing all available GNSS signals, antenna, radio modem, controller, and collapsible pole. The receiver is based on JAVAD GNSS’s new Triumph 2 chip.
Trimble BD930 GNSS ModuleTrimble has introduced its BD930 module as part of its GNSS OEM portfolio.
This small module features triple-frequency support for GPS and GLONASS plus dual-frequency support for BeiDou and Galileo constellations. Capable of receiving a wide range of commercially available GNSS signals, the 220-channel BD930 takes advantage of all available signals to provide reliable RTK centimeter-level positioning.
Spirent GSS6425 Record and Playback SystemSpirent Communications has unveiled a new system for recording real-world GNSS RF signals and replaying them in the lab.
“Record and Replay” is popular as a more rigorous — and, crucially, repeatable — approach to GPS and GNSS testing than using live signals in real time, where satellite positions and atmospheric conditions are constantly changing.

Ismael Colomina, wife Carmina, and children Jan and Eulalia on vacation in BrazilI Fell In Love With GNSS When . . .
“Two GNSS-related experiences really impressed me as a young professional and that I’ve never forgotten. The first involved adjusting a GPS-supported (GPS aerial control) aerial triangulation. By getting rid of most ground control points we managed to produce new results.
