Hello everyone.
After I successfully used one of the China CHC DGPS (Dual-frequency chcx91 gps rtk) to acquired data.

Processing the data seems very challenges for me because I am unable to installed the data processing software that came with it (Dual-frequency chcx91 gps rtk) on my computer running window 8.1

Anyone who has successfully used it or have solution idea should help me out.

Thank Nick.
I will like to know the step-by-step procedures to installed the GNNS Solution (post-processing software) for China CHC DGPS.
The software dongle came with the instrument but there is a problem when installing the software dongle to a computer with window 7, 8.1 to process acquired field data.

Probably it seems there is driver for software dongle to be installed first before the software dongle could be successfully installed.

I am a bit confused!

If you have used the China CHC post-processing software before, please kindly explained how to go out the installation of the software dongle.


 u need to change ur data to rinex file so that gnss can process it
