New GLONASS-M Satellite Begins Commissioning

New GLONASS-M Satellite Begins Commissioning

A modernized GLONASS satellite launched on last week has begun its commissioning phase in slot 18 of the Russian GNSS constellations orbital plane 3. It was the first successful GLONASS launch since the loss of three spacecraft in the crash of a Proton rocket last July.

Telemetry communications were established shortly after the GLONASS-M spacecraft (designated GLONASS number 754) reached its orbit following its launch March 23 (2:54 a.m. Moscow time on March 24), from Plesetsk space center on a Soyuz-2.1b rocket.

ESNC 2014 GNSS Innovation Competition Launches at ENC 2014

ESNC 2014 GNSS Innovation Competition Launches at ENC 2014

The European Satellite Navigation Competition (ESNC) 2014 will officially kick off on April 15 at the European Navigation Conference (ENC) in Rotterdam, The Netherlands, but the 11th round of the annual event opens Tuesday (April 1).

Launched by Anwendungszentrum GmbH Oberpfaffenhofen in 2004 with three partner regions, the ESNC has grown into a network of GNSS innovation and expertise with more than 20 regions taking part worldwide. Since 2004, the ESNC has received almost 2,400 submissions from 4,263 teams and named 204 award winners.

u-blox Releases 4-System Antenna Module

u-blox CAM-M8Q module

Swiss-based u‑blox has introduced the CAM-M8Q GPS/GLONASS/BeiDou/QZSS antenna module. The module integrates a u-blox M8 satellite receiver IC plus SAW filter, LNA, TCXO, RTC, passives, and a pre-tuned GNSS chip antenna in a 9.6 x 14.0 x 1.95 mm package.

According to the company, the surface-mount antenna module combines low power consumption with high-sensitivity, high jamming immunity, and concurrent GNSS operation (GPS/GLONASS, GPS/BeiDou, or GLONASS/BeiDou), offering a drop-in solution product designers and system integrators.

EGNOS Capability Enhanced with Addition of New Generation of Satellite Transponders

On Saturday (March 22, 2014) two geostationary L-band transponders, GEO-2s, were successfully launched on board the SES ASTRA 5B satellite from the European Space Port in Kourou, French Guiana.

The new generation transponders will provide higher accuracy positioning signals to both civil and professional users of EGNOS-enabled receivers and ensure the continuity and quality of the European Geostationary Navigation Overlay Service (EGNOS) open service and safety-of-life services for the next 15 years, according to the European GNSS Agency (GSA).

GPS Modernization Stalls

GPS Modernization Stalls

With the optimism of college-bound seniors touring the Ivy League, GPS managers have been weighing options to dramatically change the GPS constellation. Now, after studying the costs, considering the benefits, and assessing the funding climate, officials have made the starkly fiscal decision to stick close to home and take a few extra years to finish.

New GNSS Signals

New GNSS Signals

A. J. Van Dierendonck

The world’s GNSS systems are entering a phase of transformation — modernization of existing systems (the U.S. Global Positioning System and Russia’s GLONASS) and development of new systems (China’s BeiDou and Europe’s Galileo) that benefit from the lessons learned from the original GNSSs.

Notable among the modernization initiatives is an interest in implementing new satellite signal designs. These include the GPS L5, L2C, and L1C signals as well as those signals designed for Galileo and BeiDou. GLONASS designers are also working on modernized signals.

Who’s Your Daddy?

Who’s Your Daddy?

In this article, we will take a look at the various GNSS signals from the perspective of their cost-benefit tradeoffs. First, we’ll look at the evolution of consumer GPS architecture to date — where acquisition speed and sensitivity have been the main drivers of receiver architecture. That architecture has evolved rapidly to take full advantage of the characteristics of the GPS C/A code.

Galileo Works!

Galileo Works!

The objective of the IOV phase was to launch the first four operational Galileo satellites and to deploy the first version of a completely new ground segment. During this phase, the European Space Agency (ESA) needed to validate — in the operational environment — all space, ground, and user components and their interfaces, prior to full system deployment. With the assistance of industry partners, ESA had to analyze the performance of the Galileo system and its components with the objective to refine the full operational capability (FOC) system.
