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 capabilities.
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.
