Satellite Selection

Equations

The advent of multiple constellations provides the opportunity to eliminate geometry weakness as a source of satellite-based augmentation system (SBAS) unavailability. GPS users occasionally encounter areas where an insufficient density of satellites exists to support all desired operations. This most often occurs when a primary slot satellite is out of service. However, adding one or more constellations easily compensates for this geometric shortcoming. In fact, we may now experience the opposite problem of having more satellites that can be tracked by a receiver.

Clarion to Use Furuno’s GPS Receiver with DR/GNSS Module in Navigation System

Furuno GV-86

Furuno’s GV-86 GPS receiver chip with its dead-reckoning DR/GNSS module will be integrated into Clarion’s NXR16 car navigation systems for the auto-leasing and car rental industries.

The GV-86 features a dead-reckoning-enabled GNSS receiver, which receives concurrent GPS, SBAS, and QZSS satellite signals. The dead-reckoning capability allows the unit to provide positioning while receiving multiple GNSS signals in such harsh environments as tunnels, urban canyons and underground parking, the company said.

The Emerging Legal Debate Around Japan’s QZSS

Japan’s regional and augmentation positioning system, the Quasi-Zenith Satellite System (QZSS), is a project yet to be developed. While it will become a constellation of seven satellites covering the western Pacific area, only “Michibiki,” the first satellite launched in 2010 for technological validation , is now in orbit.
