Signal Disruptions
GNSS… it’s almost impossible to run a modern geo-related business without it. But what if a problem should occur? Whether in navigation, surveying or even agriculture, countless activities almost ...
Positioning
Positioning is the accurate determination of the location of an object in space, relative to a framework or datum. In geographic / hydrographic information positioning is always present to determine the location of whatever we are measuring.
Depending on the type of application the framework can be global or local. When used globally techniques such as GNSS are used and the framework is defined by geodetical coordinate reference systems. Local positioning can be done on a jobsite such as in construction and engineering with total station but in for indoor navigation.
What is GNSS Spoofing?
With spoofing attacks on the rise, survey-grade GNSS receivers need to be protected by interference mitigation technology utilizing the latest security techniques to ensure reliable positioning. The s...
GNSS receivers – evolution or revolution?
Satellite surveying… are there any industry professionals out there not using it on (almost) a daily basis? Over the last 30 years, GNSS has become the main positioning instrument for most applicati...
