GNSS Solutions is a Shareware software in the category Miscellaneous developed by GNSS Solutions. It was checked for updates 63 times by the users of our client application UpdateStar during the last month. The latest version of GNSS Solutions is currently unknown. It was initially added to our database on. Gnss Admin January 22, 2021 News Ohio-based energy provider, Dayton Power & Light (DP&L), in partnership with Sinclair College’s National UAS Training and Certification Center, is employing a fleet of senseFly eBee X fixed-wing drones to improve its large-scale data collection and mapping capacity.
For information on how C/N 0 is computed within a GNSS receiver, refer to the GNSS Solutions columns by B. Badke (InsideGNSS, September/October 2009) and E. Falletti et alia (January/February 2010).

GNSS Solutions is a comprehensive office program with all the tools required to successfully process GPS, GLONASS and SBAS survey data. It provides optimal results from any combination of static, rapid static or kinematic data. It enables you to combine background maps with land survey projects and prepare stake out missions in the office.
US Government security requirements no longer permit CDDIS to offer data via traditional unencrypted anonymous ftp; this service was discontinued on October 31, 2020. All data are still available, however access must be via HTTPS or ftp-ssl.

IGS analysis centers currently provide station position and velocity solutions to the CDDIS on a daily basis; prior to mid-2012, these solutions were issued weekly. The analysis centers provide station position, velocities, daily length-of-day (LOD) and X, Y pole positions and rates, and geocenter position solutions. The IGS reference frame coordinator retrieves these solutions and produces a combined product, which is then in turn archived at the CDDIS in SINEX format. These combination solutions are considered the official IGS products, which contribute to the International Terrestrial Reference Frame (ITRF).
Solution summary files are provided by the analysis centers in which they describe their analysis methods and strategies and list processing statistics. Descriptions of AC analysis procedures and models used are available from the IGS website.
All operational IGS GNSS products, including the station position solutions, are available in subdirectories by GPS week. The station positions and velocity files are stored in Solution Independent Exchange (SINEX) format.
In 2009 and 2013, the IGS initiated “reprocessing campaigns” (repro1 and repro2 respectively). The IGS analysis centers re-processed the GNSS data from the global network of IGS stations (from 1994 to 2007 for repro1, from 1994 through 2012/2013 for repro2) to produce a fully consistent set of products utilizing the most recent models and updated processing strategies. These reprocessed solutions are available within the weekly subdirectory structure as outlined below, in /repro1 and /repro2 subdirectories.
