1.      02/06/2025             Attention InCORS network users.

As of 12:00pm, we believe that we are starting to see successful connections to the InCORS network and the servers seem to be stabilizing. We will continue to test, and monitor. IOT staff is continuing the ongoing work of investigating the root cause. We will continue to post to our website as well as notify via email of any updates. Thank you for your continued patience.

2.      12/12/2024             Attention InCORS network users.

We will be performing some routine maintenance on the network today (Thursday, December 12th, 2024) between 10:00am and 11:00am EST. Users may experience some intermittent outages during this time. The downtime should be minimal and we will notify if it will last longer than expected. We apologize for the inconvenience as we continue to keep the network at optimal performance.

3.      8/13/2024             Attention InCORS network users.

We have recently completed our network hardware upgrade and are now offering network corrections using all 4 constellations. The network solution will now include GPS, GLONASS (GLO), GALILEO (GAL) & BEIDOU (BDS).

The IP address/port has remained the same: 108.59.49.226/9000

The following new products have been added to this port for use:

RTCM 3.2 MSM4 Nearest (MSM4_NEAR)
RTCM 3.2 MSM4 iMAX (MSM4_IMAX)
RTCM 3.2 MSM4 ViRS (MSM4_VRS)
RTCM 3.1 ViRS (RTCM3_VRS) *GPS/GLO only

There will be a certain time window for testing these products. The mount points will be shown as (_TEST) until they are determined to be working as expected.

The products with “MSM4” in the mount point name use all 4 constellations.

VRS = Virtual Reference Station**

All current mount points and message types can be found by accessing our Broadcast Corrections document here on this webpage.

* User equipment must have the ability to track the additional GAL and BDS satellites enabled on their rover. For additional information to determine whether this may be beneficial to you and how best to utilize, please contact your equipment vendor or GNSS support team.

**A virtual reference station is an imaginary, unoccupied reference station which is only a few meters from the RTK user. For this position, observation data are created from the data of surrounding reference stations as though they had been observed on that position by a GPS receiver. The main purpose of a VRS station is to reduce the baseline distance between the rover and the reference station in order to efficiently remove spatially correlated errors using differential processing and to incorporate error corrections obtained from the reference stations network. - GIS Resources, knowledge archive

4.      7/19/2024             Attention InCORS network users.

A global IT outage related to updates from Crowdstrike for Microsoft Windows systems has impacted several systems around the state and caused them to be unavailable since early this morning. This includes the InCORS network servers. Our IT staff will be working diligently through the weekend until the issues are resolved. We apologize for the inconvenience as we are unable to notify users through email due to the agency systems that are down.

5.      7/8/2024             Attention InCORS network users.

As part of our continuing effort to upgrade the InCORS network, on Wednesday, July 17th, 2024 from 12pm through 4pm, EST, we will be performing server maintenance and software installations. The network will be out of service during this time period. We apologize for the inconvenience and appreciate your patience in optimizing our network.

6.      6/18/2024             Attention InCORS network users.

All stations have been upgraded. See station upgrade section below for instructions to connect to the single base products using all 4 constellations. A network solution will be coming soon and will be announced on this webpage.

7.      5/02/2024             Attention InCORS network users.

INBU - Bluffton station located at 2800 W SR 124, Bluffton, IN has been processed and added to the network. Please see the new documents reflecting the new station name (INBU) and coordinates located on this website.

8.      3/27/2024             Attention InCORS network users.

INBF - Bluffton station located at 2800 W SR 124, Bluffton, IN has been decommissioned due to building construction. We are in the
process of building a new station (INBU) on site and hope to have it in the network by the end of April 2024. At that time, we will
notify users and publish documents reflecting the new station name and coordinates. We apologize for the inconvenience.
