Update 10/17/2023                                                                                                                                                                            The Alloy reciever and antenna cabeling was moved to a new location due to construction. The station was down from 9:40 AM to 11:06 AM on October 17th 2023. The position of the base station has not moved as the location of the antenna was not changed.

Update 08/03/2022                                                                                                                                                                            MTSU has been upgraded to a new Trimble Allor reciver and Zepher 3 antenna. This upgrade has impacted radio transmitions and MSU is working on a solution. 

Update 01/16/2019:                                                                                                                                                                  1.  The radio is now broadcasting RTCMv3.x which is supported by ALL manufactures on the same frequency that was broadcasting CMR+. The radio was broadcasting CMR+ which is a very outdated and legacy format. CMRx is the latest format but that would limit the MSU Reference Station to only supporting Trimble Receivers. This change in format was the most neutral format for all users of the reference station.                                            2. The Internet corrections ports and broadcast formats were changed to support ALL manufactures. PORT 5018 is now broadcasting CMRx which is used by Trimble receivers and is the best Data/SV packet in the industry. Port 5019 is now broadcasting RTCM v.3 which ALL manufactures support even Trimble.
