Expert Advice: The Impact of RFI on GNSS Receivers

April 1, 2015By
Dovis-Fig1-excerpt

By Fabio Dovis When subjected to very strong interference, a GNSS receiver can be totally blinded and stop working. This is often the scope of intentional jammers. However, in a number of cases the presence of interference is severe enough to significantly decrease receiver performance, but not so much as to make the receiver lose its lock on the satellite signals... read more

Spectracom Adds India’s IRNSS, Japan’s QZSS to Simulator Capabilities

March 31, 2015By
Spectracom’s GSG-6 Series multi-frequency GNSS signal simulator.

Spectracom has added capability to simulate India’s global navigation satellite system, IRNSS, and Japan’s regional satellite system, QZSS, to its GSG-6 Series multi-frequency GNSS signal simulator. The simulator is designed to be field upgradeable to simulate all current and future GNSS constellations so current customers can benefit from these features without the need for a factory return in most cases. “Spectracom understands... read more

All GNSS Attend, But Galileo Gets the Spotlight

March 30, 2015By

First and foremost, let’s give a big hand to Adam and Anastasia, the two Galileo FOC satellites that were successfully launched on March 27. Following the not-so-successful Galileo launch in August, it was imperative that this go smoothly. Although the Double-A launch occurred after the conclusion of this year’s Munich Satellite Navigation Summit, anticipation of the event set the context... read more

GNSS Constellations March On

March 25, 2015By

This week nearly all the global navigation satellite systems will push their spatial presence one or two steps further, or higher, if they perform as scheduled. Rarely if ever has there been such a concentrated period of activity in the catapult category. Are we witnessing the real dawn of the multi-GNSS era? GPS, Galileo, BeiDou, and IRNSS all have positioned... read more

Russian Company Credo-Dialogue Releases GNSS Software

March 18, 2015By

The Russian company Credo-Dialogue has released Credo GNSS 1.0, a GNSS processing software. Credo GNSS 1.0 is designed for processing of satellite geodetic measurements in differential mode. In this mode, the simultaneous operation of two or more receivers forms the baseline. The input can use the following types of data: satellite geodetic measurements and ephemeris format RINEX (2.0-3.2); satellite geodetic measurements and ephemeris formats... read more
