• Deep NRS

Redundant baseline is unique algorithm of NRS; it is used to improve the network CORS usability. For VRS solution, it uses 3 stations nearest to rover to calculate network correction. But sometimes, because of poor net speed, there is 

data delay between stations and control center or stations keep offline. For VRS solution, rover won't get network 

correction. Instead, it receives physical differential correction from the first nearest station, which is usually too far 

away to provide high accurate correction. For NRS solution, there is a great improvement because of baseline 

redundancy: if the 1st nearest station is offline, NRS will choose 2nd nearest station to join calculating network

correction, rover still get high accurate network correction.

•  Web Service

Web Service with embedded Google Map or Google Earthpackage, is anmodule designed for NRS Network CORS  management and helping ordinary users get access to various online services. As a registered user of Web service, you will benefit in the following areas 

1. Examine the working status of all registered sites.

2. Download static data from base station.

3. Check the service condition for GPS devices under your account.

4. Manage data uploading from GPS device.

5. While as an administrator of Web Service, it can help you briefly

6. Enable and disable GPS device accessing to certain services.

7. Conduct access management for base stations.

8. Store raw data.
