GNSS post-processing – the online alternative When no orientation has been given (arbitrary or OSGB36 National Grid), this method can be used to establish 2 or more known stations on-site (from GNSS). This can aid in establishing secondary control (20mm+5pmm) and allow long back-sights for traverse orientations. This technique works in areas without GPRS coverage for NRTK, or if no...

Traverse Application Program (1200 & Viva): which adjustment method is used onboard? For totals-stations, the ‘Traverse’ onboard application program can be purchased; this program guides the user through the ‘traverse procedure’ and using ATR automates prism targeting for dual-face measurements.

A quick solution if satellites are not being tracked is as follows: Select Advanced Mode in CONFIGUREOperation Mode. Now, the INIT (F6) key shows in the main survey screen; when a Real-Time Rover Configuration...

SmartRover – Bluetooth or Bust? Having recently mounted GNSS PDL-SmartRovers to quad-bikes, it was found that due to the heavy vibrations encountered on the site, the Bluetooth connections between the RX’s and the ATX1230’s antennas dropped out very frequently. The solution was to use the green-ended GEV173 cable, in a backpack configuration. This physical connection proved greatly more robust. Furthermore...
