CSDS Real-Time Network
California's Most Reliable Network
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.
What is the CSDS RTN
Achieve one-centimeter accuracy
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.
More Coverage Where You Work
Six New Stations Are Now Live In Southern California
The CSDS Real-Time Network now covers more ground than ever. Six new stations extend high-precision coverage across Santa Barbara County, Ventura County, Western Los Angeles County, and Western Kern County.
The new stations also link our Northern and Southern California networks, so you can move between jobs across more of the state and keep reliable corrections the whole way.
What's New
- 6 New Stations - Live now
- New Coverage -Â Across Santa Barbara, Ventura, western LA, and western Kern counties
- Northern and Southern California Networks -Â Are now more closely connected
- 116,500 square miles of Coverage -Â Supporting one of California's largest privately owned GNSS networks focused on the surveying, construction, infrastructure, agriculture, and utility markets
Benefits
Why Surveyors Choose the CSDS RTN
Our real-time and post-processed VRS correction services give you clear advantages over single-station RTK.
Lower Hardware Costs
You need only a rover and a cellular/IP connection, so you save about 50% compared with conventional RTK, and there's no base station to buy or maintain.
More Efficient Erews
Several crews can work at the same time, anywhere in the network.
More Productive Days
You don't have to scout base station sites, and you can start working right away. Simply Connect, Correct, Measure.
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.
