Besides the applications in positioning, GNSS has also been demonstrated as an efficient tool in atmosphere studies, and the first attempt in GLONASS
troposphere modeling can be found in the work of Dousa (2010).
There's no shortage of satellites for navigating with a WAAS GPS and GLONASS
receiver, left photo.
Like GPS, the complete nominal GLONASS
constellation consists of 24 satellites; 21 broadcasting satellites, and three on-orbit spares.
The SH0319D/E/W family of antennas provides wireless signal reception ranging from dual-bands to multi-bands covering GPS, GLONASS
, WLAN/dual-band WIFI, and GSM900/1800.
Nevertheless, the mixture of the observed GLONASS
frequencies are used for calibration and this method allows frequency-dependent GLONASS
PCV to be determined.
The main differentiator of SDCM with respect to other SBAS systems is that it is conceived as an SBAS augmentation that would perform integrity monitoring of both GPS and GLONASS
satellites, whereas the rest of current SBAS initiatives provide corrections and integrity just to GPS satellites.
This enhanced version of the SSU 2000 will be the first in a series of forthcoming Symmetricom products that include GLONASS
According to Qualcomm, adding GLONASS
improves GPS accuracy in "deep urban environments" by 50 percent.
In 2004, the Russian Space Agency announced a joint venture with ISRO to collaborate on GLONASS
The acquisition will help Sistema provide support to network operator Navigation Information Systems (NIS) to create the emergency response ERA GLONASS
under a public-private project.
Three areas of immediate mutual interest, highlighted in January 2003 during the EU-Russia seminar in Moscow, were examined: Galileo and GLONASS
(satellite positioning systems), launchers and the EU Global Monitoring for the Environment and Security (GMES) satellite programme, which covers areas such as environmental protection, global change, sustainable development, humanitarian aid, conflict prevention and crisis management.
