Caring for and checking surveying instruments between calibrations
Field checks for a level, a total station and a GNSS receiver that you can do yourself, plus a short list for transport, batteries and moisture.
Robotic total station: when one-person operation pays off
What makes a robotic total station different, what one-person work looks like on site, and when a conventional station is the more sensible choice.
Optical or digital level: the differences and when each one is enough
With an optical level you do the reading, a digital one reads by itself. What that means for accuracy, wind, low light and the budget.
What RTK is and why the accuracy is in centimetres
Where the metres of error in plain GPS come from, how a base and a rover remove them, and what fixed and float on the screen actually mean.
Total station or GNSS receiver: which one for which job on site
The two instruments complement each other rather than compete. When GNSS wins, when the total station is the only option, and how to combine them on one site.
How to choose a GNSS receiver for surveying
RTK or static, IMU tilt, radio or internet corrections. What matters when picking a GNSS receiver, and where even a good one will not help.
