Ashtech L2 Dongles for GNSS Solutions are Near End-of-Life

The L2 dongle that enabled L2 processing in GNSS Solutions is near end of life. If you think you want one, you need to purchase one As Soon As Possible. (Like today.)

This link: [ 702081-4 ] will get you the current L2 dongle price from us.

Is GNSS Solutions dead? I think ultimately—yes. That said, it currently works well and has a great baseline processor. The current free version will do you a good turn for processing L1 vectors. At (under) $1,000 it is just-fine for processing L1/L2 vectors. It is a great deal.

What is the alternative? SPSO Spectra Precision Survey Office (PN 63700-00) MSRP $2,795 + $350 / year maintenance.

What is the difference between SPSO and TBC (Trimble Business Center)? TBC includes support for a few instruments which are not supported in SPSO and it is possible to purchase a roaming network license of TBC. I can’t quote a, but the standard version is about $2,495 and the Advanced version is about $6,495.

GNSS Solutions: Processing Static, Stop-n-Go and Kinematic Jobs with VRS


Just finished a videos showing how to process static, s&g and kinematic files against a base produced by the VRS tool in GNSS Solutions. The files were made by a PM100/PM120.

You can watch it here: http://youtu.be/Ik2_-cJc96g 

It is only 3 minutes long.

GNSS Solutions, NAD83_2011, GEOID 12A, Absolute Antenna Calibrations, Updating CORS sites

If you are using GNSS Solutions in the United States to process observations, then this information may be of great value to you:
This link [ GNSS_Solutions_NAD83_G12A ] will get you a copy of the latest version of step-by-step white paper on maximizing reference frame accuracy when using GNSS Solutions with NAD83_2011 and GEOID 2012A.
The paper also shows how to
  o update all of the Antenna Calibrations with Absolute values in one step
  o import all of the NGS CORS sites in one step
  o add GEOID12A to the available vertical datum
Plus as a bonus: the top 10 GNSS Solutions Screw-Ups (from my perspective)
Happy New Year!
