CSDS Real-Time Network
What is the CSDS RTN?
The California Surveying and Drafting Supply Virtual Station Network (CSDS RTN) is a dynamic GNSS Real-Time Kinematic Network that provides more reliability, coverage, and accuracy than traditional single-base networks.
The CSDS RTN provides RTK corrections to your equipment, enabling you to achieve up to one-centimeter accuracy. With no need for a station or rover radio, CSDS RTN users are able to reduce their hardware costs by up to 50% while achieving better accuracy to your precision surveying & mapping applications.

What areas does the CSDS RTN cover?
CSDS RTN services are available over two networks:
- Northern California, which spans from Redding to Bakersfield,
- Southern California, which spans from Lancaster to Imperial Beach.
Our service area currently covers 105,000 square miles, making the CSDS RTN California’s largest GNSS network — and it's continuously expanding!
How does the CSDS RTN work?
Our network is fully redundant ensuring no signal is lost. We utilize dedicated technology that manages and monitors over 60 reference stations across California. This helps ensure accuracy and network availability regardless of power outages, loss of reference stations, or reference station movement due to seismic activity.
What products does the CSDS RTN work with?
The CSDS RTN works with virtually all major surveying and GIS/GPS products.
How can I utilize the CSDS RTN?
The CSDS RTN subscriptions are sold by California Surveying & Drafting Supply. Call 1 (800) 243-1414 or email [email protected] to find out which solution is best for you.
Benefits
The real-time and post-processed VRS correction services provide a number of significant advantages to users over single station RTK.
Hardware Costs:
- 50% savings over conventional RTK as VRS only requires a rover receiver and cellular/IP connectivity. No base station investment or maintenance costs.
Efficiency of Deployment:
- Multiple crews can be deployed at one time and work simultaneously.
Productivity Improvements:
- Begin working immediately.
- No need to investigate base station sites.
- Simply Connect - Correct - Measure. It's that easy!
Services
- Real-time data is available in a variety of subscription terms for versatility of use
- Subscriptions are also available with the rental of an RTK rover
- Post-processed data is available as a yearly subscription
After subscribing to post-processed services, go to www.csvsn.com and click "User Web Portal" to log in to your account to access and manage data files.
For real-time services you will need a valid CSDS RTN account, cellular/IP connectivity and GNSS equipment. Virtually any data-enabled modem integrated within a guidance device or as a stand-alone component can be used.
Once configured, the CSDS RTN service is very simple to use. Your local CSDS Real-Time Network's technical support representatives are always happy to assist users.
How Virtual Reference Station Networks Work
CSDS VRS Now provides positioning professionals with instant access to Real-Time Kinematic (RTK) and Post-Processing (PP) corrections utilizing a network of permanent (fixed) reference stations. With no base station or setup required, it is cost-effective, efficient and simple to use GPS/GNSS positioning based on a set of reference stations. Simply Connect. Correct. Measure.
