SmartNet Broadcast Coordinate Updates – January 6, 2020
On September 17, 2019, NGS released its new ITRF2014 and NAD83(NA2011) Epoch 2010 Multi-Year CORS Solution 2 (MYCS2) coordinates, along with GEOID18. Unfortunately, this release occurred far too late to incorporate the changes into our Fall Adjustment. Now with the Fall Adjustment behind us, activities are underway to move to these new reference frames and realizations in the US to assure consistency between NGS products, the National Spatial Reference System (NSRS) and SmartNet North America. In addition to the changes in the US, we will also be take this opportunity to adopt the current NRCAN coordinate solutions for all stations in Canada.
David E. Titcomb, PLS, runs a small but thriving survey business in Falmouth, Maine, USA. Founded in 1969 by David’s father, Robert P. Titcomb, PLS, Titcomb Associates has two offices, employs three professional land surveyors and six field crews, and has provided services to hundreds of clients in Maine, New Hampshire and Vermont, including numerous engineering firms and the Maine Department of Transportation (MaineDOT). Among the company’s key business decisions has been an unwavering commitment to providing excellent service and using best-in-class technology. It’s a forward-thinking strategy that often requires making significant investments — the sort that give many small business owners pause. But David Titcomb takes a different view.
Maine Technical Source Adds Sales Staff, Expands Service into Western PA
Maine Technical Source (MTS), an authorized Leica Geosystems dealer with locations in Maine, Massachusetts, and New York, has hired Douglas Churchill, PLS, as its newest sales and support specialist. Based in the Syracuse, NY, office, Churchill will serve engineering, construction and surveying professionals in western New York and western Pennsylvania.
On April 6, 2019, the transmitted GPS week number in the navigation message will rollover from 1023 to 0. Leica Geosystems receivers will continue to increment the week number from 2047 to 2048 and will not roll back to 0 or 1024.
Note that the required minimum firmware versions have been released years ago and that they had to be loaded already to e.g. support the leap second introduction in December 2016. Therefore it is expected that not many receivers are running incompatible firmware but this News Alert’s purpose is to make everyone aware of this potential issue.
MaCORS announced some exciting news recently. They have added a new base station on Nantucket island.
Nantucket CORS (MANT)
Also announced was the following:
“We are pleased to inform you that MaCORS RTN now offers Real-Time Products that supports both the GPS L5 signal and the Galileo satellite system. Two new RTCM 3.x (MSM4) products that offer GPS-L5 and Galileo corrections have been introduced. Please note that your equipment must support this new MSM message and be capable of tracking either Galileo or GPS-L5 signals for you to utilize these products.”
SmartNet field staff are in the New England market conducting maintenance, upgrades and new installations. This deployment will make huge strides to improve geometry, spacing and GNSS correction availability in MA, RI and CT. In addition to hardware upgrades, a number of existing stations also required an upgrade to the physical monumentation to bring the installations up to SmartNet standards.
