What is IGS?

The International GNSS Service (IGS) is a global organization that provides GNSS (Global Navigation Satellite System) data and products for a variety of applications. The IGS operates a network of GNSS stations around the world, which continuously collect data from GNSS satellites such as GPS (Global Positioning System) and GLONASS (Global Navigation Satellite System). The data collected by these stations is used to generate precise orbit and clock solutions for GNSS satellites, as well as precise coordinates for GNSS stations.

The IGS provides access to this data and products through its official website (https://www.igs.org/), and makes them available to users for a variety of purposes, including navigation, surveying, mapping, geodesy, and scientific research. The IGS also provides a platform for collaboration among GNSS researchers, users, and organizations from around the world.

Overall, the IGS plays an important role in advancing the field of GNSS by providing high-quality GNSS data and products that support a variety of applications and enabling collaboration and information exchange among GNSS professionals and organizations.

How to download data from IGS?

To download data from the International GNSS Service (IGS), follow these steps:

Create an account: Go to the IGS website (https://www.igs.org/) and create a user account. This will allow you to access the data products and download them.

Browse data products: Once you have an account, navigate to the "Data & Products" section of the IGS website to see the available data products. You can choose from a variety of products, including GNSS satellite orbit and clock solutions, station coordinate and velocity solutions, GNSS receiver and antenna phase center information, and GNSS data.

Download data: Once you have chosen a data product, you can download it in various formats, such as RINEX (Receiver Independent Exchange Format) or SP3 (Satellite Position Product). To download the data, simply click on the download link and follow the instructions.

Decompress and process data: Some data products may be compressed and will need to be decompressed before you can use them. You can use tools such as WinZip or 7-Zip to decompress the data. Depending on the data product, you may also need to process it further, such as converting it from RINEX to a different format, to use it for your specific application.

Note that some data products may require you to accept terms and conditions before you can download them, so be sure to read the information carefully before downloading.

How to Rename attribute fields in QGIS & How to Rearrange attribute fields in QGIS | తెలుగులో నేర్చుకుందాం

How to Rename attribute fields &  Rearrange attribute fields in QGIS Refactor fields Refactor fields, allows editing the structure of the attribute table of a vector layer. Fields can be modified in their type and name, using a field’s mapping. The original layer is not modified. A new layer is generated, which contains a modified attribute table, according to the provided fields mapping. Refactor layer fields allows to: Change field names and types Add and remove fields Reorder fields Calculate new fields based on expressions Load field list from another layer Add Vector Layer to Layers panel to Drop field(s) Choose Processing → Toolbox → Vector table → Refactor fields Figure 178 - Vector layer with attribute table before Refactor fields Select Input Layer (Ex: Ind_adm1) Select fields to be renamed and reorder (Ex: in the below given example Name_0 has to rename as Name with Length from 75 as 100 and change order of Name_1 under Name_0 [Name after rename] ) Figure 179 - Fi...

What is Survey Of India (SOI) Framework?

What is Survey Of India (SOI) Framework? The Survey of India (SoI) framework is a geospatial reference system used in India for mapping, surveying, and geodetic purposes. The framework is maintained by the Survey of India, which is the national mapping organization of India and the oldest scientific department of the Government of India. The SoI framework is based on the Indian Terrestrial Reference Frame (ITRF) and the Indian National Spatial Reference System (IN-SRS), and is used to determine the location and height of points on the Earth's surface with high accuracy. The framework is also used to define the horizontal and vertical reference systems for mapping and surveying purposes in India. The SoI framework provides a consistent and accurate basis for various geospatial applications, such as land management, urban planning, navigation, disaster management, and environmental monitoring. The framework is also used for the production of topographic maps, cadastral maps, and othe...

What is the difference between IGS & CORS?

 What is the difference between IGS & CORS? IGS (International GNSS Service) and CORS (Continuously Operating Reference Stations) are related but distinct concepts in the field of GNSS (Global Navigation Satellite System). IGS is a global organization that provides GNSS data and products, while CORS is a network of GNSS receivers that provide real-time data for surveying, mapping, and geodetic applications. CORS stations are typically installed at permanent locations and continuously collect data from GNSS satellites, which is then transmitted to a central server and made available to users through the internet. The IGS operates its own network of GNSS stations, which it uses to generate precise orbit and clock solutions for GNSS satellites, as well as precise coordinates for GNSS stations. The data and products generated by the IGS are used for a variety of purposes, including navigation, surveying, mapping, geodesy, and scientific research. In summary, IGS is an organizati...
