1. What is IaRTN SmartNet?

IaRTN SmartNet is Iowa's GNSS Reference Station Network. The network is based on the Leica Geosystems SpiderNet software and a system of 80 GRX1200 PRO GNSS receivers at facilities across the state. The network is designed to provide accurate, reliable, traceable and repeatable GNSS Network corrections 24/7 for the entire positioning community.


2. Is there a fee for using the network?

Currently there are no plans to charge users for access to the real-time network.


3. Who can use it?

Anyone with a network ready GPS receiver. All corrections are available thru the internet via NTRIP and TCP/IP protocols. So whether you own a Leica Geosystems rover or another make of GPS receiver you are able to gain access to the service via mobile phone technology.


4. What are the Network Terms of Use?

Please visit the IaRTN Terms of Use page for terms and conditions.


5. What type of cell phone do you need and what provider should I use?

Data services are available thru most of the major carriers in Iowa. GPRS/EDGE (T-Mobile and AT&T) or CDMA (Verizon and US Cellular) services can be used. Please select the carrier that provides the most reliable coverage for your planned area of operation. In addition to manufacturer specific cellular devices, standard cellular phones may also be used. To use a standard cell phone, please verify it has Bluetooth Dial-Up Networking capabilities and a data plan that is capable of "tethering".


6. How do I get access to the network?

Please visit the IaRTN Registration page. Once completed, we will activate your account within 24-48 hours. You will receive an email containing your IaRTN SmartNet username and password. This login is your gateway to the full suite of IaRTN services including both real-time corrections and RINEX data files.


7. How can I add additional rovers or make changes to my account?

Re-visit the IaRTN Registration page and enter the username and password you were supplied. You can add additional rovers, change contact information, etc.


8. How do I get support for my rover?

All rover support requests need to be directed to your local dealer. Leica Geosystems is not responsible for providing support for other manufacturer's equipment. If you have been advised that it is a network issue, please email us at nafta.smartnet@leica-geosystems.com


9. Where can I find out more information about IaRTN SmartNet?

Please visit the IaRTN Network Resources page for additional information!


10. What correction formats are available?

Standard formats include:
RTCM 3.1 - Single baseline and Master-Auxillary Concept (MAC) Network Corrections
RTCM 2.3 - Single baseline and iMAX corrections
CMR - Single baseline and iMAX corrections
CMR+ - Single baseline


11. What are RTCM 3.1 MAC network corrections?

Leica Geosystems, jointly with other RTCM members, has driven the development of the Master Auxiliary Concept (MAC). The RTCM 3.1 MAC network message is the ONLY internationally accepted standard for network RTK corrections. The IaRTN already uses these official correction standards. Please click here for additional information.


12. Where can I get connection information?

Assuming you have received your activation information you can find connection information for your particular rover here. Or you can find a complete list of all real time products here.


13. What is the RTK (Real Time Kinematic) accuracy?

Assuming the standard GPS RTK protocols and best practice methods are employed for maximum precision i.e. good satellite coverage, good geometry of precisions, low multipath environments etc, IaRTN typically achieves an RTK accuracy of 1-2 cm horizontally and 2-3 cm height.


14. What is the established datum for IaRTN SmartNet?

IaRTN SmartNet is on NAD(83)(CORS96)(Epoch 2002.0000).


15. Where can I get a map of the stations?

You can always visit smartnet.iartn.com and go to "Site Overview" to see a map of the stations that are part of the network. We also have a Google Earth interface available for download here.


16. Where can I get a list of stations with their locations, NGS and RTCM identifiers?

You can download the complete list of stations with their NGS and RTCM identifiers along with the city they are located in here.
