OziExplorer

Ozi instructions are always well documented, but it looks like the computer that he is using does not have an internal GPS, as he states “ GPS dongle, com 3. GPS signal ok, com 3 ok, “

Ok I will check, thanks

Ah, yes, I should have mentioned that in my reply above.

You can do it from the Moving Map menu or from the toolbar or with a CTRL S keyboard shortcut:



Then see if you can view the NMEA output.

Tried everything, will not recognise port.
I have given up now. Thanks all.

Maurice. I hadn't seen the BS 708 mouse before. I just looked it up. I notice it claims to support the following systems.

GPS, GLONASS, Beidou, QZSS and SBAS.

The QZSS in particular interests me. It is the Japanese system used to enhance accuracy. It should increase accuracy from 2- 4m, down to about 5cm.

Its path covers all of Australia, and is being trialled by the Australian Government as the new highly accurate system to augment GPS. It may be time to upgrade from the old BU 353.

Have you seen an improvement in accuracy or performance under foliage with the BS 708 compared to the BU 353?
