23/09/2020 All day
Repeat every month on theFourth Wednesday until 27/10/2021

To position aerial surveys precisely onto the National Grid coordinate system, both horizontally and vertically, often involves the marking and measurement of Ground Control Points in the survey area.  High precision GNSS technology, as sold and hired by KOREC, is ideal for this task. This course is designed specifically for those needing to use GNSS field devices to measure GCPs location precisely to National Grid in conjunction with UAS operations.

The course also reviews how additional points can be collected for QA purposes and basic topographic detail collected using the GNSS survey equipment.

Ideal for any drone operator with a need to place surveys precisely to British National Grid using the OSTN15 system.
