OVERVIEW

What is the CSDS RTN?

The California Surveying and Drafting Supply Real-Time Network (CSDS RTN) is a dynamic GNSS Real-Time Kinematic network that provides more reliability, more coverage, and more accuracy than traditional single-base networks. The CSDS RTN provides RTK & GLONASS corrections to your equipment in the field, enabling you to achieve up to 1 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 the same or better level of accuracy in their precision surveying & mapping applications.

How does the CSDS RTN work?

Each rover is equipped with a cellular internet connection an applicable data plan that connects to the CSVSN’s Virtual Reference System to acquire its GNSS correction signal. On the network side, the CSDS RTN utilizes a fully redundant server farm with Trimble Integrity Manager software that monitors 34 Reference Stations across California. This helps ensure accuracy and availability regardless of power outages, loss of reference stations, reference station movement due to earthquakes, etc. With the network being fully redundant and constantly monitored, it ensures you won’t lose signal when you need it most.

What areas does the CSDS RTN cover?

The CSDS RTN is available from Redding to Bakersfield (see coverage map). Currently, the available coverage area is 93,000 square miles, making the CSDS RTN California’s largest GNSS network.

What products does the CSDS RTN work with?

The CSDS RTN works with virtually all major surveying and GIS/GPS products.

NETWORK UPDATES

A new adjustment occurred on April 2, 2016.

  • The current IP address that you are using (50.201.146.130) will reflect our upcoming, new adjustment.
  • The current (previous adjustment) correction source will be moved to a new IP address: 50.201.146.163.  This source will be available until the November 26, 2016.
  • Your current username and password settings will give you access to the new and previous positional information.  If you need help with this please call CSDS and ask for Support.

* Be sure that you have control available to check and, if necessary, re-calibrate to after this upcoming adjustment.*

  • Leica Users: For those of you that are using the custom Leica mount points, those will be available to you on either system.  Use the IP address you want to connect to on the previously established 5010 port.

Please ensure your crews are using the correct mountpoint for the subnet they are working in.  If they choose one of the Coastal mountpoints but they are working in the Valley subnet and vice-versa, they can see 2-3 tenths in error on the positions they are receiving.  If you are concerned about this as having occurred, you can open the job and go to –> Review Job –> Ntrip Data Source.  The Ntrip sources that you have connected to will be listed there.

Be sure that you have control available to check and, if necessary, re-calibrate to after our adjustment.

When connecting to the new correction source servers (50.201.146.130) you will notice a change in the mountpoints you are connecting to.  The new mountpoints will be:

  • CSDS_Coastal_CMRp(04022016)
  • CSDS_Coastal_CMRx(04022016)
  • CSDS_Coastal_RTCM31(04022016)
  • CSDS_Valley_CMRp(04022016)
  • CSDS_Valley_CMRx(04022016)
  • CSDS_Valley_RTCM3104022016)

The existing mountpoints will be available on the old correction source server (50.201.146.163):

  • CSDS_Coastal_CMRp(12192015)
  • CSDS_Coastal_CMRx(12192015)
  • CSDS_Coastal_RTCM31(12192015)
  • CSDS_Valley_CMRp(12192015)
  • CSDS_Valley_CMRx(12192015)
  • CSDS_Valley_RTCM31(12192015)

*Leica Users
*For those of you that are using the custom Leica mountpoints, those will be available to you on either system.  Use the IP address you want to connect to on the previously established 5010 port.

If you will be using both correction sources, understand that there will be consequences for choosing the wrong source for the job you are working on. There will be coordinate differences and as such CSDS will is not liable for anyone performing work using the wrong source. Control using the current reference frame must be established or available in order 
to calibrate back onto to existing projects once our adjustment has been performed.  All jobs where you are using the current positions will need a site calibration once the adjustment is 
in place. RTN-Network-Coverage-Area

As always, proper survey practices are required when using the RTN.  All jobs need to have a site calibration performed.  This ensures that control and coordinates are relative to your job site.  In addition to site calibrations, checks should be performed before starting your survey and after ending your survey every day.  If you want to use the new more accurate correction source for your current jobs you will need to perform a site calibration.

If you have any questions, please direct them to your CSDS Sales Representative or call Support at 916.344.0232.

We at CSDS believe that you will be very satisfied with the new accuracies of the split networks and updated epoch date.

Be sure that you have control available to check and, if necessary, re-calibrate to after our adjustment.
