Trimble's preparation for 2022 involves significant changes to the North American Datum, with efforts to update geodetic libraries, improve time datum handling, and work with the new NSRS 2022. Milestones include engaging with NGS, updating software to handle modern coordinate systems, and ensuring compatibility with VRS networks. Join Trimble in embracing these advancements for accurate data collection.

Biggest change to the North American Datum SINCE NAD83 WAS ADOPTED IN 1986. In 1986: NAD83 was considered to be a geocentric datum NAD83 was considered to be equivalent to WGS84 WGS84 was considered to be a static datum VRS networks didn't exist Precise Point Positioning (eg RTX) didn't exist Our software is still largely stuck in that 1986 paradigm. It is definitely possible to get excellent results - and thousands of our customers do every day - but you need to be willing to believe "little white lies".
Trimbles Focus We here at Trimble recognize the importance of providing our customers with the ability to collect their data in a modern coordinates system.
What have we been doing? Actively engaged since the beginning with NGS Attended workshops & industry days over the past few years Invited Dr. Dru Smith to Trimble Dimensions to speak to our customer to help inform them of the changes. What have we done thus far? Using Earth Orientation and Rotation Parameters (EOP) models in baseline processing to reduce horizontal and vertical errors on all baseline lengths. (On the market) Work continues to update our geodetic libraries to work with the new NSRS 2022. We are working towards improved time datum handling Possibly including HTDP integration in Trimble Business Center between now and 2022
NTRIP Casters We are working to ensure that VRS networks broadcast meta-data identifying the reference frame that their coordinates are in. We want to get that in place well before 2022, so that when networks start broadcasting 2022 coordinates, the client software can detect that. Customers can either select the appropriate correction stream, automatically apply a transformation into the user's reference frame, or alert the user that there is a mis-match. This work involves our own CMRx correction format, RTCM and NTRIP.
Milestones Released baseline processor Released simple transformation system for Australia until we have a final solution. Engaged in talks with RTCM committee to standardize the way in which their messages include support for epochs and reference datums Introduced idea to get buy in from industry
