Hello everybody, now we can download and view DPOS post-processing results in details. Use free Justin Link software to check a solution.

I must be one of the laziest users you have. Where are the instructions for downloading and installing the free Justin link software?

Some how-to instructions would be helpful if anyone cares to put some together. When I tried to download projects from my LS I kept getting a "Can't import project (8)" message. Some files were transferred to the project folder (including a bunch of PNG icons), but I wasn't able to get beyond that.

Justin Link generated DPOS style report is quite similar to original DPOS one.

Inch Allah, thanks to Justin Link and opportunity to download DPOS projects, we have got US inches and feet in DPOS report
The same report as above but in US feet!

Wow, that's cool !! That's a point we established back in 1995 establishing H/V control for Lancaster County. It's also a data file we submitted to DPOS for a sanity check back in September. Occupied the station for an hour. DPOS processing using the GIODIS engine was < 2 cm compared to published value. The error ellipses were kind of high, but was curious about GIODIS processing. Used OPUS-RS processing also.

Thanks Alexy for your cool software, I'll have to download Justin Link (maybe purchase) !

DPOS processing using the GIODIS engine

The GIODIS engine is the preferred engine for very long baseline lengths (750+ km) while the Justin is preferred for the CORS baselines you typically find in the US. Is there any reason you have been using the GIODIS engine instead of the Justin engine?

I'll have to download Justin Link

Justin Link is free but Justin which includes post processing is available for purchase.

Just curious as stated above Matt. Was looking at the specs for both Justin and Giodis. May purchase in the near future if accountant will come off the hip.

Kind of off topic, but are there any plans to expand on the Justin software and make it more of an all-in-one utility? For example I have separate applications on my PC for Net Hub, Net View & Modem, Firmware Loader, RAMS, Justin, and JPS2RINWIN. Would it be possible to eventually make these one application? That would be awesome!

Jps2RIN(Win) is Justin module. We have no plan to expand Justin. This software is a base of DPOS post-processing. It's not good idea to rebuild and reload Justin on the server every time with any daily hardware update.
