8 GENERAL MSRN RTK USAGE

9 NGS Coordinate Change  MIDOT has not switched to NA2011  Previously scheduled for January 2012  Date pushed back to January 2013  Michigan's CORS Range of Shift is 39mm to 3mm  No Historic Coordinates will Remain in MDOT Servers  Working on State-wide or Zone Transformations by creating RTK managed products

10 MICHIGAN MSRN – COORDINATE SHIFT

11 MSRN TRANSFORMATION  Create after overwhelming response from the Surveying Group  Users wanted a way to work with NA2007 to finish existing projects for state and local agencies  MIDOT Projects can have 3-4 year lifespan  Current testing to solutions  State-wide  Local Zone (Michigan South 2113)  Created with help from Henri Ayers from Leica Geosystems

12 Transformation Report – State-wide

13 Transformation Map – State-wide

14 First Test Area

15 First Test Area – Results for Test 1

16 GLONASS/GNSS UPDATES  MIDOT network  40 receivers owned by County Partners  Only 4 county sites are GG capable  55 receivers owned by MDOT ( 7 on the Shelf )  24 Receivers are GG or GNSS capable  MIDOT has purchased the necessary parts to upgrade all its own receivers  Current Problems - MIDOT wants to upgrade to a GNSS system but funding for county owned site disappeared after some political changes inside the state.  MIDOT want to include network product for GNSS system, but due to inconsistencies in the receiver types we are unable to run any network solutions.  Possible take over of county sites by MIDOT?  GNSS Antenna Upgrades – The possible development of a standard by NGS to upgrade antiquated Antenna technology? Possibly from AT504’s to AR25’s?

17 Sites Added to MSRN by Year

18 Continuously Operating Reference Station (CORS) Typical Installations – Concrete Pillars with an Earlconic

19 Continuous Operating Reference Station (CORS) Typical Installations – Building Mounts

20 PARTNERSHIPS  Existing Partnerships  All the Michigan counties who purchased sites through Remonumentation funds  INCORS to Share Data (Network)  Shared Location with NOAA COOP water level gauges and MIDOT CORS, as with the case of Mackinaw city (MIMC) - Data from site is shared multi agency and used by MDOT, NOAA, NGS, and the Canadian Government.  Statewide Surveyors – helped with county sites that were in danger of being shut down due to county funding issues. (MILI, MIMO, MIDD)  Local business owners – MICO is hosted by a local Gas company chain  Potential Partnership  WisCORS to provide coverage along Michigan – Wisconsin border (Network and Single Baseline?)  Ohio CORS to provide coverage along Michigan – Ohio border (Network and Single Baseline?)  Possible Coast Guard sites? “ADMIRAL”

21 SERVERS CORS Diagram  MIDOT is currently working on migrating its services to a new location away from State managed systems.  This transition will be seamless for the users of the MSRN

22 SERVERS  MIDOT will keep it’s site name, but plans to off the services of our RTN software provider.  The GOAL it to become more transparent and Real-time display of site outages for users of the MSRN.  The ability for users of MSRN to add accounts, and self manage accounts.

23 SERVERS  MIDOT will keep it’s site name, but plans to off the services of our RTN software provider.  The hope it to become more transparent and Real-time display of site outages for users of the MSRN.  Also add user self managed accounts

24 FUTURE?  MIDOT management is working on a separate funding from its current system to maintain its system.  Changes in client products  Upgrade the MSRN to complete GNSS coverage rather than just GG only system compatibly.  Still be free to MSRN users!
