I was surprised to see that the PM2 isn't affected.  I haven't turned mine on in about a decade, but apparently they still work.

According to the email from Trimble we need at least firmware version 2.32; we have 4.84 on three R4-3 receivers and 5.35 on three R8s receivers so we should have a go for launch.

A new WNRO resource page from Unavco (the folks that run the Earthscope PBO GNSS array). They have links to info for all of the models/makes they have (or have had) in their inventory,  and results of some of their own tests (and an interesting video of one of those tests).

The sky is falling! The sky is falling!

GPS rollover is upon us!

I set 5 nails in the yard yesterday, in a line 5 feet apart.  I collected 2.5 hours of data with 5 receivers, 1 new Javad, and 4 older units.  I will download and process the data myself against a local CORS station and compare the results.  I will also upload each file to OPUS to verify their software is getting the same results as mine, and everything is 5ft apart and in a line.  Next week I will repeat the procedure and see if the results match.  I am only concerned with static work with these old receivers, so this is the testing procedure I came up with.

Anyone else go through testing their equipment?

I tested some Promark Xcm units ... dates were about 19-1/2 years off(August 1999), but everything else "appears", okay ... we shall see once I re-learn how to download the data, make Rinex files and how I used to change the dates on the Rinex files.

BTW ... I have 14 Promark Xcm's, and they look virtually brand new. I plan on giving 4-5 to a buddy in southern Ohio, might keep 2-3 and would like to find someone who could use what's left ...

I don't think you need a careful test of accuracy.  With this change, either it will process or it won't.
