Say goodbye to dead zones and hello to centimetre-level accuracy! Our range of professional surveying equipment is sourced from some of the industry’s most-respected manufacturers, including top-of-the-range brands and models.

From the handheld accuracy of the SP20 GNSS Receiver to precision field data collection with the Ranger 5 Data Collector. No matter the project, SEP have you covered.

We also stock all manner of GNSS/GPS accessories, including rover rods, GPS poles, mounts, connectors and adapters.

If you’re looking for a cost-effective solution, we offer a survey equipment hire service for all customers, or you can browse our used surveying equipment for top-quality products at affordable prices.

What is the difference between GPS and GNSS?: While the terms are commonly used interchangeably, there are notable differences between GPS and GNSS systems. GPS (Global Positioning System) refers to the North American satellite system. Whereas GNSS (Global Navigations Satellite System) uses the International Multi-Constellation Satellite System, including GPS, Baidu, GLONASS, Galileo and more.
What instruments are used in GPS surveys?: GNSS/GPS survey equipment covers a lot of ground – literally and figuratively. Whether you’re conducting static or kinematic surveys you’ll have accurate results right when you need them.

We offer everything from centimetre accuracy network rovers, GIS data collectors and smart antennae, to GNSS receivers, multi-band RTK (real-time kinematic) receivers and more. Reach out to us to find the best solution for your project.
What is GIS (Geographical Information System) data?: The Geographical Information System offers data on land, buildings and vegetation. The SP20 GNSS Receiver offers GIS Software for your land survey and mapping needs.
Why choose GNSS/GPS survey equipment?: With the centimetre precision of GNSS technology, you can mitigate multipath errors, increase availability, continuity and reliability, and better operate in harsh environments. This is what makes GNSS the perfect solution for mapping and land surveys.

Our friendly and knowledgeable staff are happy to advise you on the best GNSS Surveying Equipment for your specific project.
What are the weaknesses of GNSS?: Despite utilising multiple satellite constellations, GNSS signals can still be blocked or degraded by dense foliage, tall buildings, or bad weather, leading to reduced accuracy or signal loss in certain environments.
What is GNSS used for?: GNSS is used for precise navigation, surveying, mapping, and timing applications in industries like transportation, agriculture, and construction.
