I work for OGS which is an Italian Government research insitute. OGS is an UNAVCO associate member. I’m going to buy a Topcon Net-G3A and I’d like to know if the UNAVCO version as some special options enabled (e.g. high update rate, high RTK rate,...). My second question is how to take the special discount reserved for the UNAVCO members. Last time (7 years ago) I did it directly with my local retailer. Is it still the same?

The best method or configuration for streaming data out the serial port into a “Device Server” and out to an Ethernet port?

We have just received Net-G3A receivers and are evaluating firmware 3.5 See the GRIL manual for instructions on setting up TCP streams.

Has UNAVCO tested firmware version 3.5 May,06,2010? Would be interested in #2 above as well.

As stated in the product brochure available from the links above, the Net-G3A does have an internal web server. The owners’ manual contains details as to its use.

I’d like to know if this Net-G3A has a web internal webinterface as Trimble NetR8. It needs to be charged to card or firmware region of the receiver for the first time? Kind Regards Presidente Prudente, São Paulo, Brazil
