Surveying in Nigeria is evolving, and one of the biggest changes is the rise of Continuously Operating Reference Stations (CORS).

For years, surveyors relied on the traditional base and rover GNSS method. While effective, it often meant carrying bulky equipment, spending 30–60 minutes setting up a base station, and being limited to about 5–10 km coverage. Accuracy was good, but it depended heavily on how stable the base was.

With CORS-enabled surveying, things are different. A CORS is a permanent GNSS receiver that streams corrections directly to your rover through the internet. That means no more base station setup, no more worrying about radio coverage, and no need to transport extra equipment. You simply connect your rover and start work immediately.

Why CORS is a Big Deal in Nigeria

CORS saves time, money, and effort. Instead of buying and maintaining both a base and a rover, surveyors only need a rover and a subscription to the CORS service. The coverage is also wider, unlike the limited range of a base; CORS networks, such as those operated by OTIC Surveys Ltd., provide nationwide reach.

Another major benefit is accuracy in difficult terrains. Whether you’re working under dense vegetation or in busy urban environments, CORS provides stable corrections and maintains precise positioning. And because these stations are permanently fixed and monitored, you can trust them to deliver 24/7 reliability.
